1
Brandon Macchi Card
Outfielder
34th Round Pick in the June 2001 draft 
1
James MacDonald Card
Pitcher

Led the 1978 Daytona Beach Astros, the 1980 Columbus Astros, and the 1981 Tucson Toros in Wins. And for 1980, anyway, leading the Columbus Astros was also good enough to lead the entire Southern League
4
Jim MacDonald Cards
Pitcher

18th round pick in June '09 out of Boston College began his pro career at Tri City. Named an NYPL midseason All-Star, MacDonald led the V-Cats in saves and games finished
6
Jeff Mackor Cards
Catcher
High A Salem's Defensive Player of the Month for August 2004 had his best offensive year in 2006, hitting .272 with a .711 OPS. Mackor also caught Roger Clemens on June 6, 2006, taking a special one-game demotion from Salem to Lexington so that he could play the part of the Rocket's backstop as he readied himself for his last season with the Astros. Mackor was then promoted to Corpus in 2007, but only played 26 games, and only hit .219.

8
Lance Madsen Cards
Infield

Hit three home runs in a single game while playing for the Auburn Astros 8/28/1989, then the following year, led the Osceola Astros in triples with eleven.

1
Gary Majewski Card
Pitcher

Five-year major league veteran signed a minor league contract in December 2009 and spent most of 2010 with Round Rock, although he did pitch in two games for Houston, in which he posted a 22.50 ERA
12
Scott Makarewicz Cards
Catcher/Coach
1990 Florida State League All Star actually had a better year in '92 for Jackson, when he hit .287 with 15 doubles and 7 homers for the Generals--but instead the Texas League All Star nod went to teammate Tony Eusebio. Later traded by the Marlins with Jay Powell for Ramon Castro 
2

Led the 1997 Quad City River Bandits in saves with 9, and pitched three years for the Kissimmee Cobras. 
25
Rob Mallicoat Cards Pitcher 
A savage arm injury ruined what could have been an outstanding major league career. I mean, folks were saying he could've gotten guys out in the majors when he was still pitching at single A
4
Chris Maloney Cards
Manager
New Orleans manager from 2002 - 2004 and AAA All Star game coach in 2004 is also the son of Jackson General/Round Rock Express magnate Con Maloney--whose parking space I saw at Jackson one year

4

8
Monte Mansfield Cards
Pitcher
Led the 2000 Martinsville Astros with a 2.22 ERA and 15 games finished; went 9 - 3 with a 3.20 ERA and 9 saves for what appears to have been the 2004 Salem Avalanche bullpen by committee, and has since been a solid middle reliever for the first two Corpus Christi Hook squads.
2
Felix Mantilla Cards
Infield/Outfield 1965 All Star for the Red Sox was second to Ashburn among regulars on the 1962 Mets in average. Hit .219 for the '66 Astros to cap his career

Outfield

In his only year in the Astros organization, tied for the club lead in steals with the 1996 Kissimmee Cobras
53
TOMMY MANZELLA Cards Infield Third round pick in the June 2005 draft was named the system's best defensive infielder and best infield arm by Baseball America prior to the '06 season. After a disappointing offensive season at Tri-City in '05, Manzella posted average numbers at Lexington in '06. In 2007, he posted disappointing numbers at Salem, but got a promotion to AA Corpus anyway and did well there. Began '08 At Corpus and hit .299 with a .724 OPS through 54 games before receiving a promotion to AAA Round Rock, where he hit .219. Won two Defensive Player of the Month awards for Round Rock in '09, and led the team in doubles and total bases, before being named team MVP.

1
Mike Marshall Card
Pitcher

Semi-legendary righthander who would one day throw 200 innings as a reliever for the 1974 Dodgers was purchased from the Seattle Pilots in November 1969. With an 0 - 1 record and an 8.44 ERA in June of 1970, the future inventor of the Maxline screwball found himself traded to the Expos for Don Bosch
1
Violenny Marte Card
Pitcher
Dominican summer league veteran was 0 - 2 with a 5.06 for Martinsville in 2003 
1
Steve Martin Card
Pitcher
Astros I'm sure hope this 37th round pick in the June 2011 draft won't be so wild and crazy
10
Tom Martin Cards
Relief Pitcher 
Provided excellent relief work in 55 games for the 1997 NL Central division champions, going 5 - 3 with a 2.09 and a couple saves. Threw in 20 games for the '05 Round Rock Express.
3
David Martinez Cards
Pitcher
Three-year veteran of the Venezuelan Summer League played at Greeneville Tennessee in 2009, and was 1 - 4 with a 4.50. Promoted to Tri-City for 2010, he posted a 5 - 2 won/loss record to go with a 57:11 K/BB ratio. Tri-Ciity Pitcher of the Month for August 2010. 37 Games with 5 Wins and 2 Saves at Lexington in 2011

3
Eric Martinez Cards
Infield
1991 New York-Penn League postseason All Star at DH won his club's triple crown, pacing the Auburn Astros in average at .320, in RBI with 58, and in homers with 9. Mysteriously did not progress, however, and was out of the system after 1992 
2
Ernest Martinez Cards
Infield

University of Central Florida graduate signed as a free agent could not cut the mustard at Auburn in 1992, hitting .219
26
JD MARTINEZ Cards Right Field 20th round pick in 2009 out of Nova Southeastern University not too far from the Astroman hit .403 with 5 homers in 19 games at Greeneville before getting a promotion to Tri-City, where he hit .326 with 7 in 53. South Atlantic League MVP in 2010 despite having been promoted to AA Corpus in July, and organizational Player of the Year to boot. Played at AA Corpus in 2011, at least until getting called up to the majors on July 29th, and doubling in his first major league at bat
2
Louie Martinez Cards
Pitcher
Juan Luis evidently preferred Louie and went 2 - 2 with a 6.75 for the '91 Auburn Astros 
8
Marty Martinez Cards
Catcher/Infield Infielder acquired from the Braves in exchange for Bob Aspromonte hit .308 in 78 games for the 1969 team that fell just a little short of winning the first NL West division title. Tailed off from there, though, and was traded to the Cardinals in November of '71 for future Replacements guitarist Bob Stinson 
5
Ronnie Martinez Cards
Pitcher
Led the DSL in ERA for 2002; 6 - 4 with a 2.39 for Martinsville in '03, and led the T-City Valley Cats in strikeouts for 2004. Went 11 - 2 with the '04 ValleyCats, and was named New York Penn League MVP. In '05, he co-led the SAL in wins while pitching for Lexington. Pitched at three levels in 2006, reaching AA Corpus Christi, but struggled once he got there. Pitched only at Corpus in '07, but the ERA was high
1
Randy Martz Card
Pitcher

Righty was 17 - 19 in the majors and spent his last professional year with the '85 Tucson Toros
1
Larry Mason Card
Pitcher
1963 signee spent five years in the Astros' chain, having his best year at Salisbury in 1965, when he was 6 - 2 with a 1.83. Played another three years in Mexico and was rediscovered by TCMA in 1981 
4
Roger Mason Cards
Pitcher Pitched 1-1/3 innings for the 1989 'Stros with a 20.25 ERA, but was 7 - 12 with a 3.54 for that year's Tucson Toros. Would end up throwing over 400 innings in the majors for seven different teams 
16
John Massarelli Cards Catcher/Coach/Mgr
8th Round Pick in 1987 hit .276 in 1917 at bats in the Astros minor league system, was a 1988 postseason All-Star in the New York-Penn League, and played in the 1990 midseason Florida State League All Star game. Finished his playing career in Taiwan before returning to the Astros to coach, and ultimately manage, at Michigan, Auburn, and Salem
3
Chuck Mathews Cards
Pitcher

Went 32 - 16 in the first three years of his career (7 - 3 at Auburn in 1983, 13 - 7 at Daytona Beach in 1984 and 12 - 6 at Osceola in 1985), with good ERA's, then had a 5 - 6 record with a 6.01 at Columbus in '86, and was thereafter out of baseball.
6
ED MATHEWS Cards
3rd Base Last hurrah for the 'Stros in 67, and hit .238 in 101 games before being moved on to his final resting place in Detroit in a deal that saw a return of Fred Gladding 
1
Terry Mathews Card
Pitcher
6 - 5 with a 3.67 for the 1993 Jackson Generals, before moving on to the Marlins and their Edmonton affiliate
4
TJ Mathews Cards
Pitcher 
Oakland and St. Louis thought he might end up being their closer; Houston in 2002 would've been satisfied with anything more than the 18-2/3 innings he gave them before breaking down
12
Ron Mathis Cards
Pitcher Led the 1983 PCL in shutouts while pitching eight complete games over 182 innings. Named the fifth starter in Houston at the end of '85 spring training, he went 3 - 5 in 23 games before being sent back down to Tucson. Spent '86 entirely at AAA and most of '87, too, going 10 - 7 to earn a 12-inning, 0- 1 callup to the dome at the end of the year. 
19
David Matranga Cards Infield 2001 Texas League and AA All-Star got his first callup to Houston in 2003, and homered in his first major league at bat, on June 27 of that year. 
67
Kazuo Matsui Cards 2nd Base One of the first signings in the Ed Wade era began 2008 on the DL but made an impact once he got going, with a game that included patient approach, skillful bunting and defense that certainly looked better than his NL position-high error total might have suggested. Then came a second DL stint . . . . After a 2009 in which he played in only 132 games and OPSed .659, Matsui found himself released in May 2010
1
Mick Matuszak Card
Trainer

Trained for the 1991 Auburn Astros, replacing Mark Copeland, who had trained in 1990
12
Jason Maule Cards
Infield

Average years in his debut at Auburn in 1999, and his followup at Michigan in 2000, but had a monster breakout in 2001 for the BattleCats, when he led the Midwest League in runs and OBP, and was second in average, while also stealing 56. After hitting .263 at Round Rock for 2002, was lost to the Yankees in the AAA phase of the 2002 Rule V draft
17
DERRICK MAY Cards Outfield 1996 Opening-Day rightfielder was author of fifth Pinch Hit Grand Slam in team history 9/5/95 vs. the Reds at the Dome 
13
LEE MAY Cards
1st Base 81 homers in three years and '72 NL All-Star, but only John Bateman in team history had more at bats with a higher strikeout-to-on-base ratio. That would make him also a: 
12
MILT MAY Cards
Catcher 
Acquired from the Pirates for Jerry Reuss after the 1973 season, May hung around long enough to drive Bob Watson in for baseball's reputed millionth run, then was dealt to the Tigers with Dave A Roberts and Jim Crawford for nobodies like Terry Humphrey, Mark Lemongello, Gene Pentz, and Leon Roberts. Milt May was also with the 'Stros long enough to be confused with Lee May on the 1975 Hostess issue
2
Johan Maya Cards
Infield
Hit .239 in his stateside debut at Martinsville in 1999, was brought back for 2000 at Michigan and hit .206 
4
JOHN MAYBERRY Cards
1st Base Another soon-to-be-great player traded away by the incredibly dense Spec Richardson: Mayberry hit .300 in minor league stops at Greensboro in 1968, at Cocoa the same year, at Oklahoma City in 1969 would of course be replaced by Tal Smith as GM after the 1975 season, the worst in team history. 
3
LEE MAYE Cards
Outfield Acquired early in '65 from the Milwaukee Braves in a deal that sent away Ken Johnson and Jim Beauchamp, Maye would lead off on Opening Day of 1966, and hit .288 that year in 115 games, the highest average among regulars. His career as an R & B singer is discussed here, at www.group-harmony.com, and you may view his 1966 Topps # 162 by clicking this 
1
Cesar Mayora Card
Pitcher
Righthander was 2 - 3 with a 4.54 for the '05 Greeneville Astros then pitched at Greeneville again and at Tri-City in 2006
20
Edwin Maysonet Cards Infield 19th Round Pick hit .275 in his debut for the 2003 Tri-City Valleycats. The following year at Lexington, he led all Astros--minor or major league--in triples with 10. By 2007, he had reached AA Corpus, and had acquired a nice reputation as a plus fielder. Round Rock's starting shortstop for 2008, and hit .271. Got 7 ABs in a September callup, getting his lone hit September 17, in a 14 - 2 loss to Florida. Maysonet performed better by far in Houston than in Round Rock for 2009, seeing a couple weeks of decent playing time for Houston when Kazuo Matsui was placed on the DL with a bad hamstring in late May. Expected by some to make the 2010 squad out of spring training, Maysonet was instead assigned to Round Rock. Missed most of May and all of June with hamstring injury and was thus not in the equation when Matsui was released May 20. Ended up playing 90 games for RRx and hitting .248
1
Josh McAfee Card
Catcher
Acquired straight up for Brian Dallimore from the D-Backs in April, 2000, McAfee hit .155 for the Kissimmee Cobras that year, backing up Brandon Buckley and Scott Chapman 
1
Steve McAllister Card
Infield
1981 Gulf Coast League All-Star for the Astros Orange squad hit .273 that year, .248 the nest at Asheville, and .197 at Daytona in 1983, then was released 
2
Jason McCarter Cards
Pitcher
Best season was his last one in the Astros' organization, as in 1998, he threw 70 innings and notched four saves for the Quad City River Bandits
3
Tim McClaskey Cards
Pitcher

June 2003 free agent signing finished the year and came back for 2004, eventually pitching in 49 games for the Express, winning 12 and losing 13. Pitched in the organization again in 2005, and finished first in WHIP and second in innings pitched for AA Corpus Christi
4
Todd McClure Cards
Pitcher
1988 Florida State League All-Star was traded to the Minnesota Twins on December 4, 1988 for Mark Portugal. Portugal would win 52 games for the big league Astros, and McClure would be out of baseball by 1990. 
1
Tom McCraw Card
Coach Having seen the rotund and nearly immobile McCraw on the bench, you'd probably be surprised to hear that a young McCraw finished second in the American League in triples and tenth in stolen bases for the 1968 season as a member of the Chicago White Sox. As hitting coach for the late 90's Astros, became something of a tutor to Derek Bell after Derek had faded 
1
Justin McCray Card
Infield

Hit .287 in 61 games for the '90 Asheville Tourists, but only walked 7 times and homered twice
1
Ryan McCurdy Card
Catcher
NDFA was third catcher at Tri-City in 2011, and hit .324 while OBPing (.388) higher than he slugged (.382)
3
Jim McCutcheon Cards
Pitcher
Not sure why the man has a Quad City card, as it appears that all McCutcheon did in 1993--his last year in baseball--was go 1 - 2 in 16 games with a 7.30 for Asheville, and Asheville only 
2
Danny McDaniel Cards
Pitcher
Lefthander pitched a year in the independent Northwestern League before getting another chance in the 2003 Carolina League. Signed by Salem, he went 5 - 1 to earn a shot with Round Rock in 2004. The Austin native responded with a 4 - 3, 3.36 season for his hometown Express 
1
Von McDaniel Card
Infield

A phenom for the 1957 Cardinals--One month out of high school, he 2-hit the 1957 Brooklyn Dodgers in his first major league start--McDaniel saw his pitching career derailed by a sore shoulder (and an infinite ERA for the 1958 Houston Buffaloes). Switching to the infield for the 1959 season, McDaniel then played three years for the Oklahoma City '89ers between 1962 and 1964, hitting .247, .215, and .195, respectively, before his release.
1
Jim McDonald Card
Infield

Not to be confused with Jim MacDonald, the 1980 Southern League wins leader, this McDonald hit .286 with 5 homers and 41 RBI's for the '82 Tucson Toros and .270 with 2 and 21 for the same-year edition Columbus Astros
4
Mike McDowell Cards
Pitcher
5 Round Draft Pick in 1989 out of Eastern Washington bucked the odds for a couple years, getting as high as Burlington in 1991 
1
Joe McEwing Card
Infield Super Joe was purchased from Kansas City on the eve of the 2006 season, then spent most of the year at Round Rock, and was named Express MVP after the season
3
Leon McFadden Cards
Shortstop 
[McFadden had] grown up in Los Angeles in a mixed neighborhood and never had a single racial encounter until he was a baseball player in Georgia [probably as a member of the 1964 Durham Bulls]. The team bus stopped at a restaurant and all the players piled in. The man behind the counter asked McFadden if he'd like to come back and eat in the kitchen.
'I really didn't think anything about it at first,' McFadden said. 'I thought maybe they had another room in the back, someplace more comfortable. It just didn't register. So I said No thanks. I'll sit here.'He was soon enlightened by the [Billy Goodman.'I was angry. I had a package of crackers in my hand and I just threw them down, walked out and sat in the bus.' After a while his teammates came out bringing him food, and he got angry at them for that. 'I realized later that they were just trying to be nice to me. But when that kind of thing happens, you don't think straight. I was so hurt and so angry I could feel the tears in my eyes. I didn't know whether to cry or punch somebody.'
2
Chris McFerrin Cards
Pitcher
The 1997 Media Guide says:Had a hand in 24 of Auburn's 37 victories in 1996 as he was 4 - 2 with 20 saves in 33 games. He tied for first in saves in the New York-Penn League while his appearances tied him for second.
1
Randy McGarvey, Jr. Card
Catcher
.238 at Tri-City in 2003
1
Clint McGill Card
Catcher
Signed as an NDFA at the age of 23 in February of 2005, and made his professional debut with single A Lexington that April--probably an interesting story in there somewhere. 
6
Brian McGlone Cards
Shortstop

5th Round selection in the June 1990 draft played three years in the early '90's, hitting both his homers at Auburn in 1991

Nate McGlone Card
Coach
Strength and conditioning coach at lancaster in 2011

Catcher
No relation to Campbell, we believe 
1
Doug McGraw Card
Pitcher

December 1993 Rule V pick up from the White Sox organization pitched in '94 for Osceola, and was mistakenly given the back of Jimmy Lewis' 1994 card by the people at Classic.
2
Terry McGriff Cards
Catcher 
Primary catcher at Tuscon in 1991 who had five at bats for the big club in 1990, and also happens to be Gary Sheffield's godfather
2
Joe McIntosh Cards
Pitcher
Ambidextrous pitcher traded with Larry Hardy--in Tal Smith's fourth move after taking over for the axed Spec Richardson--in December of 1975 for Doug Rader never pitched for the big club, and wouldn't even pitch in the minors for them until 1979, for Gulf Coast 
1
Larry McIver Card
Outfield
A member of the 1981 Astros Orange Gulf Coast entry, and the 1982 Auburn Astros 
1
Matthew McKee Card
Batboy

The snivelling kid
3
Mickey McKee Cards
Infield

Possessor of an undergraduate degree in mechanical engineering from Tulane, and another member of that 2001 Lexington Legends squad that may have been the most dominant minor league team in franchise history
2
Ron McKee Cards
GM
SAL Executive of the Year in both '84 and '90 had his snivelling kid put in the '89 Asheville ProCards set 
9
Ryan McKeller Cards
Pitcher
Had a predeliction for giving up the long ball at Martinsville in 2003, with 4 in 37-2/3 innings, but otherwise had a fine 3 - 0, 3.58 campaign. Led the 2004 Tri-City ValleyCats in earned runs and was second in innings pitched. Despite 4.00 ERA's at two stops in 2005, was still considered to have a bright future by those in the organization, as he was invited to the Ryan camp prior to the 2006 season. Finished 24 games for the '07 Salem Avalanche, while compiling a praiseworthy 2.84 ERA. 4 - 6 with a 5.89 at AA Corpus in 2008. Split '09 between AAA Round Rock and Corpus, striking out 78 while walking 25 in 81-1/3 IP 
1
Jim McKnight Card
Infield

Hit .295 with 32 RBI for the 1981 Florida State League Champion Daytona Beach Astros
23
Tony McKnight Cards Pitcher 1995 Number One Pick and team leader in ERA for the 1999 Jackson Generals was moved out by the Hun at the trade deadline in 2001 for what turned out to be a remarkably mediocre Mike Williams. McKnight left behind a 5 - 1 career record with a 3.91 ERA for the Astros, which included a four-hit complete game shutout vs. his future Bucs teammates, pitched September 27, 2000.
4
Bo McLaughlin Cards
Pitcher Number One pick in the June '75 draft--while also spending time at AAA Memphis and Charleston--went 9 - 15 with a 3.90 over four years and 203.1 innings with the big club. Possessor of two 1 - 0 complete game shutouts for the 'Stros (one over ten innings, McLaughlin was traded to the Braves in May of 1979 for reliever Frank LaCorte 
1
John McLaren Card
Coach/Catcher
Beginning in 1970, spent seven years in the Astros' minor league system, at Covington, Columbus, Sumter, Cocoa, Iowa, Dubuque, and Memphis. But although he played and scored a run in game three of the triple header, his biggest regret may be that he didn't catch Eleno Cuen's no-hitter for his 1972 Cocoa Astros
1
Tio McLean Card
Pitcher
Pitched in 10 games for Greeneville and Gulf Coast in 2009
2
MARK MCLEMORE Cards
2ndBase 
Opening Day Starter in 1991 didn't learn to hit 'til after he left Houston; he's a lifetime .259 hitter with a .349 career OBP, but managed no better than .148 with a .221 before his July release that year
47
Mark McLemore Cards Pitcher Fourth round pick in the 2002 draft got knocked around at Tri-City that year, and at Lexington the next, .jpg 
3
Don McMahon Cards
Pitcher Durable right handed reliever would pitch 1310 innings before he was through, and pitch for seven teams, but only the 1963 Houston Colt .45's ever allowed McMahon to start a game. Actually, they allowed him to start two for them, and he lost both. But was 6 - 8 otherwise over most of two season with the Colts, and had a 2.81 ERA in 100 games 
3
Craig McMurtry Cards
Pitcher 
1994 AAA All-Star would break picket lines during the 1994-95 strike--McLane is on record as saying that McMurtry would have been the team's 1995 Opening Day Starter had the strike not ended--then pitch in 11 games for the big club the following year. Which made his teammates about as happy as you might think. . . .
18
Buck McNabb Cards Outfield
1991 Second Round Draft Pick and '92 Midwest League All-Star was perhaps the best minor league player from the early to mid nineties farm system never to get a big-league at bat
2
Patrick McNair Cards
Pitcher
43rd Round Pick in the 2001 draft had five saves over 70 innings for the 2002 Lexington club
33
Aaron McNeal Cards 1st Base
Next Big Thing--who led the 1999 Midwest League in homers and was named both the league and the BattleCats' MVP--became trade bait after a wrist injury sustained while with Round Rock in 2000 dampened his power stroke. The player McNeal was traded for--Shortstop Cristian Berroa--hit .325 in his one year for the BattleCats in 2001, didn't get a minor league card for some reason, and was lost to the Rockies in the 2001 Rule V draft.

Geoff Meadows Card
Pitcher

Shown as Jeff on his 1982 TCMA Auburn Astros #7, although the Doyle database shows "Geoff." Anyway, 0 - 2 with a 9.50 for the 1981 Astros Blue Gulf Coast squad, and 2 - 5 with a 5.49 for the team with whom he makes his card appearance.

Louie Meadows Cards Outfield Make no mistake: he's no Mike Fischlin. But Meadows, after hitting .300 in the minors three times, remains one of only 18 non-pitchers with over 100 major-league at-bats for Houston to finish with an average under .200

Dave Meads Cards Pitcher
The organization isn't showing a great deal of faith in you when they lend you out to an independent club for your second professional year--as the Astros did with Meads in 1985, when they let him pitch the South Atlantic League season with the unaffiliated Gastonia Jets. But Meads struck out 130 while walking only 30 in 146 innings for Gastonia, and the Astros made sure not to lend him out for 1986. And a 4 - 3 recordwith the '86 Asheville Tourists got him to AA Columbus by the end of the Southern League campaign. Meads made his major league debut April 13 of the following year, and got his first win ten days later, when, relieving Danny Darwin with an Atlanta Brave on second with two outs in the top of the seventh, he struck out Ken Griffey on three pitches. Meads was done for the day, but the Astros rallied in the bottom frame, and he had the W.

Tomas Medina Card
Pitcher

Tomas also enjoys soccer, music, and pizza, says the back of his 1997 Auburn card. I guess they were stumped for better material, as the ERA's--in the DSL, in the GCL, in the FSL, and in the New York-Penn--were very high.

ROMAN MEJIAS Cards
Outfield
Until Jeff Bagwell connected twice on the first day of the season, 2003, Mejias had been the only player to homer twice on Opening Day for the Houston National League club, doing it in the Colt .45's inaugural game on Aril 10, 1962. Mejias was easily the greatest offensive force for the first year club, but would be traded to Boston in November of '62 for two-time AL batting champ and big-time disappointment Pete Runnels.

Hector Mercado Cards
Pitcher
Without a doubt Mercado's most notable year within the Astros chain was 1994, when he notched a decison in each of his first twelve starts while posting a 2.35 ERA over that span. Unfortunately, FSL All-Star nod notwithstanding, the record was only 5 - 7 at that point, and he kinda fell apart from there, finishing 6 - 13 with a 3.95

48th round pick broke out at Lexington in early 2009, converting his first 9 save opportunities, and posting a 19:3 K/BB ratio. Promoted to AA Corpus shortly thereafter, and did OK. Began at Corpus in 2010, and led the Hooks in games finished and saves. 7-game promotion to Round Rock didn't go so well

Tony Metoyer Cards
Pitcher
Began his career as a third baseman with Auburn in 1984, hitting only .175, then converted to pitcher. Threw for three more years in the Astros chain, his best year being 1987, when he went 7 - 3 with a 2.72 for a very good Osceola staff. Pitched in 1988 for the unaffiliated Carolina League Virginia Generals, and in 1989 for the unaffiliated Miami Miracle of the FSL. For 1990, he was off to Taiwan, where he pitched for seven years. He then closed his career by pitching for four years in the Mexican League, and has more recently coached for Baseball USA

CARDS I HAVE PLAYER POSITION REMARKS

Dan Miceli Cards
Pitcher I guess there are some that feel his scathing, small-minded critique of John Boles DIDN'T lead to that worthy man being fired as manager of the 2001 Marlins, but I'm not buying that s&^ here. Still, Miceli acted the team player in his stay as an Astro, and was rather valuable as a setup man in 2004 after the departure of Octavio Dotel and the promotion of Brad Lidge to the closer's role. Struggled in the playoffs, to put it mildly, however.

David Miller Cards
Pitcher
The tallest player in Tri-City ValleyCat history (surpassing the previous holder of this distinction, Evan Englebrook) was 2 - 0 for the V-Cats in 2007, and 3 - 2 in 2008 before being released in November. On June 21, 2008, Miller threw four hitless middle-relief innings to combine with starter Shane Wolf and finisher Ashton Mowdy in posting the first no-hitter in ValleyCat history in a 10 - 0 shellacking of the Oneonta Tigers

Not the Dodgers guy at one time on everybody's hot list, but the guy acquired on December 15, 1999 along with Adam Everett for Carl Everett. Although he had a 90+ fastball and a good curve, a 2002 injury set him back, and 2003--with ERA's over 5.00 at Round Rock and New Orleans--was his last year in the organization

ORLANDO MILLER Cards Shortstop Acquired from the Yankees on March 13 of 1990 for Daven Bond and ex-Olympian David Silvestri, Miller was immediately fallen in love with by the card companies upon his acquisition by the Astros. And a 1990 Sally League All Star pick seemed to confirm everything. But the defense was horrendous throughout the minors, and got no better once he got to the majors, where he hit like he had for the most part in the minors: in the .260's. Nevertheless, Miller, before his trade to the Tigers in December of '96, became one of only eleven Astros in the nineties to have hit 20+ doubles in back-to-back years during the decade.

Relief Pitcher 5 - 2 with a 4.02 over the 1998 and 1999 seasons for the big club. Was especially good in '98, when he appeared in 37 games, going 2- 0 with a save, and actually made a spot start, on September 15, 1998, in an 8 - 4 loss to the Mets that wasn't his fault. Acquired by the Astros in the first Ausmus deal, Trever was sent to the Phillies at the end of spring training 2000 for human blowtorch Yorkis Perez. Returned to the Astros fold in 2006 and with the departure of Mike Gallo , became the club's lone lefty specialist for 2006. Joined by Mark Mclemore in that role for '07, Miller most distinguished himself that year by appearing in a major-league record 76 games without a decision--though he did notch one save.

Catcher 
The desperation of the mid 80's Astros to find someone, anyone who could take Alan Ashby's place has been written about elsewhere, but sure is interesting to note that when Mizerock got his first major league at bat in 1983, he had:a) never hit higher than .257 in the minorsb)somehow managed to be named to the 1982 Southern League All Star team despite hitting .229.After hitting .185 during the Astros' 1986 Division championship year, Mizerock was released on October 24, and was thus already history when his two 1987 cards hit the streets. . . Both Robbie Wine and Mark Bailey would survive the 1987 season, but would not get through the '88 campaign, and Craig Biggio would make his debut June 25 of that year, effectively ending the "masquerade."

Dave Mlicki Cards
Pitcher Super Dave was acquired from the Tigers on June 23, 2001 in exchange for faded 20-game winner Jose Lima. Went 7 - 3 the rest of the way, and got the nod for (and the losss in) game two of the NLDS vs. the Braves. 4 - 10 in 2002, Mlicki was not invited back for '03. Still, one of only three Astro pitchers with five innings or more pitched to have a postseason ERA of 0.00

Doug Mlicki Cards
Pitcher
Brother to Dave was drafted in the 12th round by the Astros in 1992, and got as high as AAA Tucson in 1996. His 1995 Signature Rookies Authentic Signature # 37 notes that the curveballer Mlicki led the '93 Osceola squad in innings pitched, walks, and strikeouts, and that he had "established himself as Houston's best pitching prospect, outside of Billy Wagner."

Three starts, 13.7 IP, and 12 Earned Runs later, he was on the DL for the remainder of the season. Returned as bullpen help in '07, and didn't do half bad. Re-signed for '08, Moehler made a couple emergency starts early on, and comported himself fairly well.

Joe Moeller Card
Pitcher
Drafted by the Astros from the Los Angeles Dodgers in the 1967 rule V draft, Moeller was returned to the Dodgers nine days before the start of the 1968 season, and thus became one of the few '60's era players (along with Manny Mota and the ever-hated Donn Clendenon) to have an appearance on a baseball card as a Houston player but to have never appeared in a regular season game

Montalvo himself gave up a triple, and an earned run. After that Montalvo went back to Tucson, where he played the remainder of '86 and two more years.

The Mets showed about as much faith in Mora's ability as the Astros had, and traded him with others to altimore for Mike Bordick. Mora has been a three-time All-Star for the Orioles, and finished 18th in MVP for 2004

Jorge Moreno Cards
Infield

Third round pick out of Fresno State in 2006 hit .180 at Tri-City that year, and didn't improve the average much at Lexington in '07, though he did boost the slugging a good deal with ten jacks. Split '08 between Lexington and Salem, while also missing time because of a broken bone in his hand when he was hit by a pitch. Played at Lancaster and at Corpus in '09, hitting .233, then lost to the Nationals in the December Rule V draft

OMAR MORENO Cards

Outfield
Appeared in 37 games at short, 6 games in the outfield, and a bunch more as a pinch-hitter for the 2000 Texas League champion Round Rock Express. Hit .295 that year and was invited back for 2001, although he was not able to repeat his performance (.183) for the 2001 League runners-up

JOE MORGAN Cards 2nd Base
Two stints with the 'Stros but wearing a Reds cap in the Hall. Which kinda makes sense, as contrarians aside, he really was much better after he left the Astros

Alvin Morman Cards
Pitcher 29 - 12 as a farmhand in three seasons, and 4 - 1 as a Houston Astro, although the ERA didn't always match. An amazing 8 - 0 with a 1.55 in 1992 for the Asheville Tourists, and 8 - 2 with a 2.96 the following year for Jackson. After giving up 8 homers in 42 innings for the 'Stros in '96, however, was traded to Cleveland for Jose Cabrera.

Jose Mota Cards
Outfield
No relation as far as I know for this outfielder who got as high as the Florida State League for two years in the late '70's. Mike Lally, a teammate of Mota's with the '75 Covington Astros, says that Mota "could absolutely fly on the basepaths," though Lally also remembers that Jose was also picked off quite a bit.

Manny Mota Card
Outfield
Acquired from the Giants with Dick LeMay for Joey Amalfitano in November of 1962, Mota spent spring of 1963 at Geronimo Park at Apache Junction but was traded to the Pirates five days before of the start of the 1963 season for health food freak Howie Goss, and thus accumulated exactly 0 of his 150 career pinch-hits in a Houston uniform.

15th Round Draft Pick in 2001 had his best year at Michigan in 2002, when he was third on the club in homers (10) and doubles (25). Played for the Salem Avalanche in 2003, but only hit .235, and was, evidently, released

Tony Mounce Cards
Pitcher
Began the 1995 season for Quad City by spinning 19 consecutive scoreless innings, and ended it by leading the league in wins with 16. Went on to finish second in ERA in the Florida State League for the 1996 Kissimmee Cobras, but couldn't make a seamless transition to higher-level minor-league ball. Despite being named a 1997 Midseason Texas League All-Star, he finished the year with a 5.03 ERA. After that, it appears he was not considered quite so highly within the Astros organization. Released some time after the 2000 Media guide went to press, Mounce has most recently been signed by the Yakult Swallows of the Japanese Central League.

JAMES MOUTON Cards Outfield 1993 Pacific Coast League MVP for the Tucson Toros led off Opening Day in '94, but never quite bellied up with the OBP or the Stolen Bases. But the K's were really the problem. I guess it's pretty logical to say that it's OK to strike out a little bit if you've got the extra bases, and if so, the contrapositive also holds. So you might then finger the worst offenders by calculating:
(Total Bases - Strikeouts)/Plate Appearances).
Figuring minimum 1000 plate appearances, and through the end of 2003, Moises Alou (at .404) leads the Astros all-time in this particular stat--and he's got more than a 100 point lead over his second-place uncle Jesus. James Mouton, on the other hand, is fourth-worst on this list, ahead of only defensive wizard Tim Bogar, Eric Anthony (who did hit a few homers, but struck out so prodigiously that they were nullified for all intents and purposes), and Mark Bailey. So in the end the promise was belied, and Mouton was an unlikely

Pitcher
19th round pick in the June 2008 draft finished tied for second on the Tri-City ValleyCats in strikeouts with 48, and, on June 21st, despite walking the bases loaded in the ninth, closed out the first no-hitter in Tri-City history, finishing what Shane Wolf had started and David Miller had handed to him. Fine 33:8 K/BB ratio at Lexington in 2009. Rated as having the best curve in the organization by Baseball America prior to the 2010 season. 2 - 3 with a 4.91 for Lancaster in 2010

Josh Muecke Cards
Pitcher
Fifth round pick was 3 - 3 with a 4.14 in 2003 as a starter for Tri-City, then went 9 - 1 mostly out of the pen in 2004 for Lexington. Won ten games in 2005, and was Carolina League Pitcher of the Week May 22. A wrist injury on Opening Day while pitching for Corpus in 2006 presaged a poor year, but Muecke returned to lead the Hooks in innings pitched and wins for 2007. 8 - 13 with a 4.89 for Round Rock in 2008, but named to the AAA All-Star team, and pitched a scoreless inning in the game, held July 15 in Louisville. Became a free agent after his year at Round Rock in '09, when he was 7 - 11 with a 4.90 for the Express.

Radical move made by Garner and Purpura in the Spring of 2006 to install Munson -who had previously played all of one inning as a major leaguer behind the plate--as the team's backup catcher didn't really work out, but it wasn't a disaster, either.

2004 NCAA Division II Pitcher of the Year at Texas A & M Kingsville jumped to rookie ball after June, and was only 2 - 3 with a 6.43 for the Greeneville Astros, but had a very nice 20/6 strikeout to walk ratio. After a 2005 at Lexington which featured an ERA over 7.00, Murdy returned to the SAL and finished second on the club in innings pitched and third in appearances, all while maintaining a solid 3.38 ERA. Released, however at the end of March '07
