Rodriguez was placed on the 15-day disabled list on June 7 because of the injured finger, the same one he slammed in a bathroom door two weeks ago. The time off could help Rodriguez restore his confidence, after a tough stretch of wildness that saw him lose the closer’s role.

Closer Drew Storen, who threw a bullpen session for the second time since he underwent surgery in early April to remove a bone fragment from his right elbow, could be evaluated by Johnson and the Nationals staff next week when he returns to throw in front of them.

“He’s playing catch everyday, has been for about a week,” Johnson said. “I think he could come [back] pretty quick and hopefully will be ahead of the schedule the trainers have set out for him.”

Storen is slated to return to the team in a month or less.

Johnson also said that reliever Ryan Mattheus, who has been on the disabled list since May 22 with plantar fasciitis in his right foot, could be ready to return soon. Mattheus pitched a scoreless inning on June 13 for Class AA Harrisburg.

“We’re just going to make sure that his foot doesn’t bother him,” Johnson said.
