Manager Ryne Sandberg said he is uncertain if Rollins (hamstring) will play again this season, the Phillies' official site reports. "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." Rollins ran the bases Saturday and is showing some signs of improvement. He has been out since Sept. 8 with a strained left hamstring.
