Rollins progressing, but return uncertain

OAKLAND -- Jimmy Rollins, who has been out with a strained left hamstring since Sept. 8, continues to work on running the bases, and it remains unclear whether he will return this season.

"There is improvement," Phillies manager Ryne Sandberg said after Saturday's 3-0 win over the A's. "He was working on the rounding aspect of running. He did pretty well with it. We'll check him out tomorrow, continue to check him out day to day to see how he progresses with all that."

Asked if Rollins will play again this year, Sandberg said: "We'll see. We'll see how he does and how he goes. I'm not going one way or another on it. Just watching the progress. He's doing good with what he's doing."
