Alvarez departs with left knee discomfort

PITTSBURGH -- Pedro Alvarez left the Pirates' Tuesday night game against the Dodgers in the fifth inning with left knee discomfort.

Alvarez had doubled to lead off the bottom of the fourth against Dodgers right-hander Josh Beckett and tagged up and went to third as Jordy Mercer flied out to the warning track in left-center. Alvarez seemed to be limping slightly on his way and, after being stranded at third, was removed from the game at the start of the fifth.

Josh Harrison replaced Alvarez at third base.
