Oakland A's 3B Danny Valencia exits game with 'left hamstring tightness'

Oakland A's third baseman Danny Valencia did not take the field for the bottom of the second inning after running the bases in the top half in Monday's contest against the Boston Red Sox. He was diagnosed with "left hamstring tightness," the beat writers are tweeting out. Valencia returned from the disabled list last Saturday from a strain in that same hamstring. There is no word on whether Valencia will miss any time as a result of Monday's injury.

Valencia appeared to be in pain after running to first base on an infield single but remained in the game to score a run after a visit from A's manager Bob Melvin and a trainer. Chris Coghlan entered the game at third base in Valencia's place.

Valencia didn't look right when he ran out single, nor comfortable the rest of the way around the bases. If hamstring again, that's trouble.
