Mets shortstop Jose Reyes left Saturday afternoon's game against the Yankees with a tight left hamstring. Reyes is expected to undergo an MRI on Sunday to determine the extent of the injury. He doesn't think he will miss significant time, but noted after the game that he still felt tightness and pain in the hamstring. "It changes the look of the team, for sure. No question," manager Terry Collins said. "We've got to find somebody to step in his role and step in his place. We don't expect them to do what he does." Reyes suffered the injury while hustling down the line to beat out an infield hit in the bottom of the first. The shortstop said he felt "something weird" in his hamstring halfway down the baseline. He attempted to steal second later in the inning but stopped short and turned back to first.
