No future Astros, only former Astros with birthdays today ~
1B/3B/OF Aubrey Huff (36)
A fifth round pick by Tampa, Huff came to Houston in a July 2006 trade for Mitch Talbot and Ben Zobrist. In 68 games for the Astros in 2006, he hit .250/.341/.478. He went on to play for Baltimore where he earned a Silver Slugger, Detroit and San Francisco where he earned World Series rings in 2010 and 2012.
LF Keith Lampard (67)
Drafted by Houston in the second round in 1965, Lampard played in 62 games for the Astros in 1969 and 1970, hitting .238/.289/.393. In nine seasons in the minor leagues, he hit .289/.316/.470.
RHP Marc Valdes (41)
Originally drafted by the Marlins in the first round in 1993, Valdes came to Houston in a May 2000 trade with Tampa. In 53 appearances for the Astros in 2000, he was 5-5 with a 5.08 ERA and a 1.659 WHIP. After playing, he became a coach in the Mets organization. In 2012, he was the pitching coach for the Brooklyn Cyclones of the New York-Penn League.
MGR Cecil Cooper (63)
As manager of the Houston Astros for parts of 2007 and 2009 and all of 2008, he compiled a 170-170 record. Of all the things I could remember Cooper for, I actually most remember him for his freakishly large hands.
