Matt Kemp, who didn't look to be running full speed as he scored from first base on a first-inning double by Andre Ethier, left the game before the start of the second inning in Dodger Stadium after apparently aggravating his hamstring, and was replaced by Tony Gwynn Jr. in center field.
Kemp, who was in his second game since returning from the disabled list for a left hamstring injury, was captured by television cameras breaking a bat over his leg in apparent anger before disappearing from the dugout into the clubhouse.
UPDATE: The Dodgers announced, via Vin Scully on television and via Twitter, that Kemp did reaggravate his left hamstring and will undergo an MRI test tomorrow.
