He was struck by a 93 mph cut fastball on a 1-2 count. Werth immediately slammed his bat to the ground in disgust and slowly moved up the first base line, where he was met by manager Davey Johnson and head athletic trainer Lee Kuntz.
Werth appeared to be trying to convince Johnson to let him stay in the game, but he was removed.
Brian Bixler pinch ran for Werth, but was stranded at first base, and replaced him in right field. The Nationals trail 10-2 after six innings.
