Mike Lowell, 3B
Mazz's grade: B
Clearly, the hip injury has been a major factor, but we all know the rules: If youre on the field, youre expected to produce. At the All-Star break, Lowell was batting .297 and was on pace for 22 home runs and 95 RBI; since that time, hes batted .225 with four homers and 16 RBI. More and more, he seems doubtful for the playoffs. That could be a big blow.
