Kevin Youkilis, 1B

Fast fact: Hit .342 with runners on base, .242 with the bases empty.

Lowdown: It's happened every year, but never more significantly than in 2007: After first-half stats of .328 average, .921 OPS, and 40 strikeouts in 293 at-bats, Youkilis sank to .238, .747, and 65 in 235 at-bats in the second half. With the addition of Sean Casey, the team might get Youkilis some of the rest he clearly needs as the season goes on.
