Phillies manager Charlie Manuel said Placido Polanco (back) will not be the everyday third baseman when he returns from the disabled list. "No," Manuel said. "I probably won't be able to throw him out there every day. We definitely need him back because he is a good defensive player." The chances are good that Polanco still playing more than anyone else at third, but the Phillies like what they've gotten from Kevin Frandsen so far and won't totally banish him to the bench. Polanco, who is batting just .255/.300/.328 this season, will begin a rehab assignment with High-A Clearwater Wednesday and rejoin the Phils Saturday.
