Right-hander hurt attempting to cover first

OAKLAND, Calif. -- Oakland's Rich Harden left his start Saturday against the San Francisco Giants in the third inning after partially dislocating his non-throwing shoulder while trying to cover first base.

Ray Durham's chopper was fielded by first baseman Scott Hatteberg, who fired a wild throw toward Harden at first. The right-hander lost his footing trying to make the play and stumbled. He came up grimacing and grabbing his left wrist area.

Trainer Larry Davis ran onto the field and Harden left the game. Justin Duchscherer entered in his place.

Harden threw 35 pitches, 21 strikes. He struck out three, walked one and allowed a first-inning double to Durham.

Hatteberg got an error on the play.
