SAN FRANCISCO -- Nationals right fielder Jayson Werth was in the lineup Wednesday afternoon against the Giants, but he was a late scratch for the second day in a row because of a right ankle injury.

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.

Hairston serves suspension in series finale

SAN FRANCISCO -- Because he is suffering lower back spasms, Nationals third baseman Jerry Hairston Jr. decided to serve his one-game suspension Wednesday afternoon.

In the bottom of seventh inning on May 27, with Padres left-hander Clayton Richard on the mound and Nationals second baseman Danny Espinosa on first base, Hairston called time out. Home-plate umpire Ed Hickox declined, while Richard threw the pitch. Hairston quickly went back into the batter's box and flied out to center fielder Cameron Maybin for the second out of the inning.

Instead of running to first base, Hairston argued with Hickox, claiming that Richard was quick-pitching him and wasn't giving him enough time to set up in the batter's box.

Within seconds, Hickox ejected Hairston and almost hit manager Jim Riggleman in the face accidentally as he was waving his arm to indicate that Hairston was out of the game.

Two days later, Major League Baseball issued the suspension and an undisclosed fine to Hairston for his aggressive actions, which included making contact with Hickox.

Hairston maintains he didn't touch Hickox.

"There wasn't any possibility I was playing today, to be honest," Hairston said. "You might as well serve [the suspension]. Get it over with. The donation [fine] will be very well spent. It will be going to the Baseball Assistance Team.

"I want this over with, anyway. I know Ed wants it, too. He is a good umpire. In this game, it sometimes happens. It's over."

Hairston said his back issues are getting better and he hopes to play against the Padres on Thursday.
