The Houston Astros have always had a team that was based on strong pitching. From the 1980s with Mike Scott, J.R. Richard and Nolan Ryan to their most recent World Series run with Roy Oswalt, Roger Clemens and Andy Pettitte.

I have compiled a list of who I think are the top 15 starting pitchers in the history of the Houston Astros.
