Kemp, who just two seasons ago finished runner-up to Milwaukee's Ryan Braun in the NL MVP voting after hitting a career-high 39 home runs with 126 RBIs and a .324 average, is batting .251 this season with two homers and 17 RBIs in 51 games, and has struck out 60 times in 191 at-bats following offseason shoulder surgery.
The arbitrator's decision last week to overturn Braun's suspension marked the first successful appeal of a suspension under Major League Baseball's anti-drug policy.
