Jason Varitek, C
Varitek has been struggling at the plate all season. He heads into the break with nine homers and 40 RBIs, and is hitting .232 -- far below his career average of .269. He is just 3 for 28 in July. Varitek, however, has been instrumental in handling the pitching staff. The revolving door on the mound has kept him busier than usual. The backstop has caught for 10 different starting pitchers so far this season.
