Ty Wigginton has committed eight in just 21 starts at third base. Mike Fontenot, who was designated for assignment on Wednesday, made two in 25 chances, and Kevin Frandsen committed his first on Wednesday.
"Mistakes are going to happen. But you can't just keep making them," manager Charlie Manuel said before Thursday's series finale against Washington. "You make too many of them -- we need to correct them. ... Polanco is a very sure fielder. He's got tremendous accuracy on his throwing arm. He is a very good fielding third baseman."
Polanco went on the DL retroactive to July 23, so he is not yet eligible for activation. Manuel said he expects the veteran third baseman back at some point, but it's unknown when.
