In the seventh inning, with runners on first and third and Washington leading, 2-0, Phillies catcher Carlos Ruiz tried to pick off Werth at third base, but Ruiz's throw hit Werth on the right elbow and bounced toward the tarp near the stands. Werth scored easily, but was in obvious pain. He left the game immediately and iced the elbow.
Manager Davey Johnson is hoping that Werth is able to play in the three-game series against the Braves at Nationals Park, which starts on Friday night.
"I hope he is ready for the Atlanta series because we want to be spoilers," Johnson said.
