Jason Giambi's first triple in six years, since 2002, chased Scott Feldman with two outs in the sixth inning.
He leaves with a 2-1 lead and Frankie Francisco will try to hold it against Jorge Posada.
Giambi's three-bagger was driven deep to right center. It just ticked off the tip of Josh Hamilton's glove and Hamilton slammed into the fence and went sprawling on the warning track.
The ball bounced away from centerfielder Marlon Byrd and the slow-footed Giambi was able to "scamper" all the way to third. He was stranded there, though, when Francisco struck Posada out with a high fastball.
The other good news is that Hamilton appears injured from his fall on the track.
Mike Mussina is gone after six, replaced by reliever Edwar Ramirez.
