SAN FRANCISCO — San Francisco Giants All-Star right-hander Matt Cain left Saturday's game against San Diego after getting hit by a liner in his pitching arm during the second inning.

Cain, who entered the game tied for the second-most wins in the National League, was hit just above his right elbow by San Diego pitcher Tim Stauffer's line drive with two outs. The ball ricocheted off Cain toward the third-base dugout as the Giants pitcher grimaced in pain while walking around on the field.

Cain then circled back behind the pitcher's mound where he was met by trainer Dave Groeschner, manager Bruce Bochy and pitching coach Dave Righetti. After a brief conversation, Cain attempted to throw a warmup pitch, but the ball sailed over the head of catcher Eli Whiteside and hit the backstop.

Cain was then replaced by right-hander Justin Miller.

He had two strikeouts and allowed four hits in his shortest start since Sept. 3, 2007.

The 24-year-old Cain was voted to his first All-Star game last Sunday, along with teammate Tim Lincecum.
