LHP Frank Riccelli (60)
A first round pick by the Giants in 1971, Riccelli came to Houston in a June 1978 trade with the Cardinals and pitched in 13 games for the Astros in 1978 and 1979 with a 3.60 ERA and a 1.640 WHIP.
C Brian Esposito (34)
A fifth round pick by the Red Sox in 2000, Esposito came to Houston as a free agent in November 2008. He played in three games in the major leagues (two for Houston in 2010) with three plate appearances and he is still looking for that elusive first major league hit. He played most recently in the Cubs organization.
