White Sox GM Kenny Williams has “heated exchange” with hitting coach Greg Walker

All is not well in White Sox land.

Amid a report last week that the relationship between Kenny Williams and Ozzie Guillen is “beyond repair,” Daryl Van Schouwen of the Chicago Sun-Times reports that the White Sox GM recently had a “heated exchange” with hitting coach Greg Walker.

Williams told reporters last month that he preferred the swing second baseman Gordon Beckham had when he was first drafted out of the University of Georgia in the first round of the 2008 draft as opposed to the one he has now. Walker took it personally. The two exchanged in the tunnel at U.S. Cellular Field, which led Williams to tell Walker to clean out his locker. The situation was resolved by White Sox chairman Jerry Reinsdorf.

“I’d rather not comment on it,’’ Walker told the Sun-Times on Friday. “What goes on in our clubhouse stays in our clubhouse. It’s been a very frustrating year for a lot of people.’’

It’s tough to blame the hitting coach for the failures of Beckham, Adam Dunn and Alex Rios, but the White Sox enter play Saturday ranked 11th in the league in OPS and 12th in runs scored. None of the White Sox coaches are signed beyond this season and Van Schouwen reports that most of them are confident they will not return.

The White Sox lost 8-1 to the Tigers last night and now 6 1/2 games back in the American League Central.
