In the bottom of the 6th inning, Jorge Posada singled and then advanced to second on a Melky Cabrera ground out. As the YES replays showed, Posada grabbed his left hamstring while nearing second base. While he was safe, he would be removed from the game for Hideki Matsui in the bottom of the 8th. The news from the clubhouse is not good: Posada has reportedly reaggravated his strained his left hamstring, and he will go for an MRI tomorrow. Since the Yankees are carrying only Jose Molina, I would expect a roster move in a few hours.
