Nationals Manager Davey Johnson double-switched Ryan Zimmerman out Saturday night's 6-3 loss in the ninth inning, which turned out to be an early start on a long break for Zimmerman. Johnson, feeling that Zimmerman is tiring, will give him the day off Sunday, allowing Zimmerman two consecutive days off with Monday's scheduled off day. Zimmerman underwent surgery in May to repair a torn abdominal muscle that kept him out months. Johnson said Zimmerman has no specific injury now, just typical wear and tear. "I know he's been dragging," Johnson said. "He's just so valuable to the ballclub. I wanted to give him a breather, but we've got an off day coming Monday. I'm planning on giving him tomorrow off. I saw it the last few days, three or four days."
