Werth hurt the ankle Monday in the eighth inning of the Nats' loss to Giants while chasing a ball near the bullpen mound. The next day, Werth was able to take batting practice and entered the game as a pinch-hitter in the eighth inning. Facing reliever Javier Lopez, Werth grounded out, running gingerly to first base.
There isn't any talk of putting Werth on the disabled list. Werth is optimistic that he can play Thursday against the Padres in San Diego.
"I could probably play today, but I wouldn't be able to run too well," Werth said.
