Coming up on just 63 years, the Houston Astros have a relatively short history compared to other MLB franchises. Originally named the Houston Colt .45s upon their inception in 1962, the franchise became the Astros in 1965.
In that short time span, they've had their fair share of legendary players, from the great Nolan Ryan to the killer B's led by Craig Biggio and Jeff Bagwell, to a current legend like Jose Altuve; the Astros have had more star power than many clubs with a longer history.
Officially, there are 10 retired numbers in the Houston Astros' history, with Billy Wagner's number 13 being the most recent entry following his selection to the Hall of Fame earlier this year.
