It might be worth it for the Tigers to make a play for Astros pitcher Roy Oswalt, according to the Detroit Free-Press. The team has struggled this season because of the inconsistency of their pitching. They are counting on Max Scherzer, who they recalled on Sunday. Oswalt is on the hook for $23 million through 2011. The Free-Press writes that the Tigers have the prospects needed to acquire Oswalt from Houston.
