One day after coming off the 15-day disabled list, Los Angeles Dodgers All-Star center fielder Matt Kemp aggravated his left hamstring while scoring from first base on a first-inning double by teammate Andre Ethier on Wednesday night against the Milwaukee Brewers.

Kemp's stride slowed noticeably as he came around third base. He left the game immediately and was replaced in center field by Tony Gwynn.

"I don't know what happened," Kemp said. "It's just kind of gave out. It's definitely frustrating, having just come back, and now I will be sitting out a while. ... I tried to hide it, but there really was no hiding this."
