The Venezuelan Outfielder, Richard Hidalgo, had his best years in Major League Baseball playing for the Houston Astros.  Hidalgo had a major season in 2000 when he smacked 46 Home Runs with a Slash Line of .314/.391/.636, but knee injuries prevented him from getting anywhere near that again.

An excellent selection from the Expansion Draft, Turk Farrell was converted to a Starting Pitcher and was an All-Star in his debut season for Houston.   Farrell would make two more All-Star appearances, and while he has a losing record as an Astro, it was not like he had a lot of help around him.

Roger Clemens was only a Houston Astro for three years, but when he arrived at age 41, he showed everyone that he was far from done yet.  Clemens made an immediate statement in 2004 when he went 18 and 4 and become one of only a handful of pitchers to win the Cy Young Award in both leagues.  Clemens would finish 3rd in Cy Young voting in his second season winning the ERA and FIP title.  His tenure was brief, but his stats were phenomenal.  With Houston, "the Rocket" went 38-18 with 505 Strikeouts and a 2.40 ERA.

Doug Rader was known for his defense and he was a five-time Gold Glove winner at third base.  Playing his first nine seasons in Houston, Rader did not always hit for the best batting average or on base percentage, but he did hit over 100 home runs as an Astro and 1,060 Hits.
