In the top of the seventh inning with the Nationals leading, 6-0, and right-hander Sam Dyson on the mound, Werth hit a leadoff single near the right-field line. Werth tried to stretch it into a double and was thrown out by right fielder Giancarlo Stanton.
"I like to be an aggressive baserunner," Werth said after the game. "I felt when [Stanton] cut the ball off, which was a surprise, I still thought it was going to take a perfect throw. He made a perfect throw. … I would take that chance tomorrow if I had the opportunity."
After Werth slid awkwardly into second base, he was seen limping back into the dugout. He was replaced by Nate McLouth in right field to open the bottom of the inning.
"I won't know [how bad it is] until I wake up tomorrow," Werth said. "It will probably be a little sore. I'm going to try to play. I expect to play, but it could be sore.
"It's one of those things. The first time you sprain your ankle, it's the worst. ... I wasn't real sure at first. I wasn't feeling a whole lot better right away. They got me out of there to get some ice on it. Hopefully, I'll be available tomorrow."
