"Greg Walker's hitting duties will expand this winter and could take him to places as far as Puerto Rico and California.

The White Sox's hitting coach plans to stay in contact with Carlos Quentin and Alex Rios, who struggled this season.

"We've got to square some things up going into next spring training, and I've got some ideas what I want to do next winter with both of them," Walker said. "I've already talked to them about it. We're all on the same page with it."

Quentin will undergo surgery Tuesday to have a pin removed from his surgically repaired right wrist. After his rehabilitation, Quentin plans to experiment with a few things he has discussed with Walker, who wants him to regain the command of the strike zone he displayed during his 36-home run season in 2008.

"He's going to talk to us on the phone, and he might come out and see me," said Quentin, who resides in California. "We've been brainstorming to get better. We have agreements to what I want to clean up."
