Williams anticipates quick recovery by Desmond

PHILADELPHIA -- Nationals manager Matt Williams said Ian Desmond's right thumb was sore, but the skipper expressed hope that Desmond could play Saturday night against the Phillies.

Desmond hurt the thumb when facing Orioles right-hander Darren O'Day in the eighth inning Thursday night. With runners on first and second and two outs, Desmond worked the count to 2-2, then Day hit Desmond on the right thumb with a fastball. Desmond writhed in pain for a few seconds before he went to first base.

Desmond went out to the field to play defense for the bottom of the inning, but he did not have a good feel for the ball and was taken out of the game.

Desmond had treatment on the thumb and was able to throw the ball a little bit on Friday, Williams said.

"I don't expect it to be more than just a day. We'll see how it goes," Williams said. "Night game tonight, we have a night game tomorrow. He should be fine. It's day to day."

In the meantime, Danny Espinosa was able to get the start at short against the Phillies on Friday night.

Werth's left foot OK after late tension vs. O's

PHILADELPHIA -- In the ninth inning of Thursday's 4-3 loss to the Orioles, Nationals right fielder Jayson Werth was facing left-hander Zach Britton and fouled a ball off his left foot. Werth was in pain and took his time going back into the batter's box.

Meanwhile, Orioles manager Buck Showalter was seen telling Werth to get back in the box. Home-plate umpire C.B. Bucknor was also trying to tell Werth to get back in the box. Nationals manager Matt Williams and assistant athletic trainer Steve Gober came out of the dugout to aide Werth.

"Jayson fouled that ball off the top of his foot; it's painful off the top of the foot," Williams said. "He has no gear on. C.B. was encouraging [Werth] to get back in the box with the game going. Jayson needed a little more time, so we decided to go out."

Werth ended up grounding out to end the game. He said his right foot was all right, and he was in the starting lineup against the Phillies on Friday night. However, he declined to comment on what was said by Bucknor and Showalter.
