Yankees C Posada leaves with right calf tightness
Jorge Posada has left the New York Yankees' game against the Baltimore Orioles with tightness in his right calf.
It was unclear when Posada was injured, but the Yankees announced he would have an MRI on Monday night. Francisco Cervelli replaced him behind the plate before the start of the sixth inning.
Posada missed two straight starts last week with a swollen right knee after he was plunked by a pitch from Baltimore pitcher Jeremy Guthrie, who also started Monday night's game.
