Nationals injury updates (Werth, Espinosa, Hairston, Slaten)

SAN DIEGO - There are a few Nationals injury updates to pass along, so we’ll just run through them in rapid succession:

* Danny Espinosa, who got hit in the left hand with a pitch at the end of Wednesday’s game in San Francisco, is back in the lineup tonight. X-rays showed no broken bones in his hand, assuaging the second baseman’s worries, and he’ll hit sixth against Padres right-hander Aaron Harang.

* Jayson Werth is back in the Nationals’ lineup tonight, after missing the last two games with a left ankle injury when he tripped over the bullpen mound in San Francisco trying to track down a fly ball. He’ll hit third tonight. Manager Jim Riggleman said Werth still isn’t 100 percent, but he’s doing well enough that he can play. And at Petco Park, the Nationals could use his bat.

* Jerry Hairston Jr. is still out of the Nationals lineup, after leaving early on Tuesday with back spasms and sitting out yesterday’s game, serving a one-game suspension on a day where injury would have prevented him from playing anyway. Hairston said he thought he could play tonight if he was needed, and though his back still isn’t 100 percent, he’s feeling much better after getting treatment for it. “I can breathe,” Hairston said. “That’s the biggest thing.”

* Doug Slaten, who’s on the disabled list with left elbow ulnar neuritis, still isn’t doing much. “I’m not hearing anything about him,” Riggleman said. “Rest is what I’m hearing there. He’s not throwing or really doing anything like that.”
