PHILADELPHIA — Phillies pitcher Cole Hamels left Thursday's series finale against the Milwaukee Brewers after being struck in the shoulder by a line drive.

One pitch after giving up a two-run homer to Ryan Braun in the fourth inning, Prince Fielder laced an infield single that hit Hamels in the front of his left shoulder.

Trainers immediately tended to Hamels, who left the game with what the team called a left shoulder contusion. He was replaced by J.A. Happ.

Hamels was the MVP of the 2008 NL Championship Series and World Series, but is off to a rough start this season. He had an 11.17 ERA through his first two starts.

He had cruised through the first three innings Thursday, striking out six of the nine batters he faced.
