TORONTO — Baltimore right-hander Daniel Cabrera won't pitch again this season because of a strained elbow.

Cabrera, 8-10 with a 5.25 ERA in 30 starts, experienced pain and tingling in his elbow during a side session Wednesday and returned to Baltimore for tests. He underwent his second MRI in a month today, revealing no damage.

"They put an old MRI side by side with the new MRI and there's nothing like that," manager Dave Trembley said before Baltimore's game against the Toronto Blue Jays.

Cabrera was originally slated to start Friday against the New York Yankees but Radhames Liz was moved up to start on regular rest in the opener of the three-game series. Chris Waters is scheduled to start the final regular-season game at Yankee Stadium on Sunday but Trembley hasn't announced who will handle the middle game.
