WASHINGTON -- The Nationals activated right-hander Brad Lidge from the 15-day disabled list Thursday and placed right-hander Henry Rodriguez on the DL with a strained right index finger, retroactive to Wednesday.
After the Nats' 3-1 loss to the Mets on Thursday afternoon, manager Davey Johnson said Lidge will be available when the team travels to Boston for a three-game series with the Red Sox beginning Friday night.
"The trainer came to me today and said that Henry was getting treatment every day for that finger, the index finger on his right hand," Johnson said. "Immediately, even though I liked the way he threw with the bum finger on Tuesday, I just told Henry, 'We just have the luxury right now ... if this was in July or August, I wouldn't even be considering it.'"
Lidge underwent hernia surgery on May 1 after making seven appearances in April. In seven innings, Lidge posted a 5.14 ERA with seven strikeouts and seven walks. Lidge made two rehab appearances with Class A Potomac, the most recent coming Wednesday night against Frederick. Lidge struck out two while pitching a hitless eighth inning.
Rodriguez, meanwhile, has been mostly ineffective, posting a 5.14 ERA in 21 innings.
"In talking to [pitching coach Steve McCatty], any time you have a strained joint, it's going to nag you for a while," Johnson said. "The thought process was, well let's just nip it right in the bud and not have something lingering all year long with him. Certainly, he's too valuable an asset. We want to get rid of it right now. We have the luxury of having a lot of guys who are ready to pitch."
