Matt Kemp hasn't been driving the ball this season, which may indicate that he's still building strength in his shoulder.
The outfielder had offseason labrum surgery on his left shoulder.
Kemp hasn't done much on inside pitches -- through Wednesday, he was 6-for-27 (.222) with one walk.
During his MVP-caliber 2011 season, he hit .402/.447/.698 with 14 home runs on inside pitches.
