Jimmy Rollins isn't expected to miss much more of the Philadelphia Phillies' postseason push.

Rollins was diagnosed Monday with a strained right hamstring, after an MRI exam in Philadelphia ruled out any major problems such as a significant tear. Phillies manager Charlie Manuel said he expects Rollins will be back with the team when its three-game series at Florida continues Tuesday.

"He might be able to pinch-hit or something," Manuel said before the Phillies faced the Marlins. "I don't know if he'll be ready to be back in the lineup Tuesday or Wednesday. He's still going to be sore."

Rollins experienced tightness in the hamstring after hitting a double and eventually scoring against the Marlins on Sept. 8, leaving that game and not playing since.

For the season, Rollins is batting .245 with seven homers and 37 RBIs. Still, it's clear that the two-time reigning NL champions are much better when their shortstop is in the lineup.

Entering Monday, the NL East-leading Phillies were 51-31 when Rollins plays this season, 32-30 when he does not. When Rollins scores a run, Philadelphia is 30-6, as opposed to 53-55 when he doesn't cross the plate.

"I hope we have him back Tuesday," Manuel said.

Rollins has been on the disabled list twice already this season, missing more than two months with a strained right calf. Since returning for the second time in late June, he's been batting .235 with five home runs and 30 RBIs in 69 games.
