Matt Kemp set for MRI on hamstring

LOS ANGELES -- 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."

Kemp, who broke a bat over his knee in the dugout before heading to the clubhouse, will undergo an MRI on Thursday to determine the extent of the injury. Both Dodgers manager Don Mattingly and Kemp said they believe Kemp will take another stint on the DL.

"It wasn't [Mattingly's] fault my hamstring flared up," Kemp said. "I was frustrated because I love to play the game. I can't be mad at Donnie B. It was just the frustration of being out."

Kemp spent 15 days on the DL with a left hamstring strain he originally suffered May 13 against the Colorado Rockies. He appeared to be fine during a two-game rehabilitation stint with Triple-A Albuquerque earlier this week and during his first game back from the DL on Tuesday night against the Brewers.
