Roy Oswalt retires after 13 seasons
Oswalt was a dominant force for the Houston Astros in the early 2000s, finishing in the top 5 in National League Cy Young voting 5 times in 6 seasons between 2001-06.
He closed out his career with shorter stints in Philadelphia, Texas and Colorado, where he wasn't quite the same ace that he had been in Houston, but still somewhat impressive.
He finishes his career with a 163-102 record and a 3.36 ERA, good for 8th among active pitchers before his retirement.
Oswalt had a very good career, and while he may not have punched his ticket for Cooperstown, he was an ace for the Astros for years and should be very proud of what he has accomplished.
