Our friends in ESPN Stats & Research offer some interesting info on Dustin Pedroia.
Pedroia twisted his right knee on May 15 against the Tigers, and since that time his production has dropped off considerably.
The Sox second basemen is hitting .167 and slugging .208 since the date of his injury. Before the injury, Pedroia was hitting .297 with a .547 slugging percentage, including all eight of the HR that he has hit this season.
The splits are even more dramatic when looking at his performance against fastballs (see accompanying chart).
