Phillies manager Ryne Sandberg is not sure Jimmy Rollins (groin) will be ready to play shortstop this weekend. Rollins started a second straight game at designated hitter Thursday but has not started at shortstop since Sunday. The Phillies are playing the Mets this weekend, so obviously the DH spot won't be available. "We'll see," Sandberg said about Rollins being ready for shortstop this weekend. "It's day to day with how he's doing. He felt good about [a pregame workout Wednesday]. Good progress with that. I think that keeps it a day to day thing, though, so that's positive."
