White Sox general manager Ken Williams is discussing a new contract with club owner Jerry Reinsdorf, SI.com has learned.

Williams is said to be amenable to an extension, and people familiar with the talks expect a new deal to be consummated fairly soon.

In an exceptional ode to privacy, Williams' contractual situation appears to be such a secret that it remains unknown when his current contract ends, though it's not believed to be expiring after this season. The extension is thought to be for multiple years.

"I have never commented on my contract status. We have never announced any terms or length of any of my deals and most people around here have respected my desires to keep such things private,'' Williams said in an e-mail, declining once again to confirm any negotiation.

Reinsdorf is known to be fiercely loyal to his employees, but Williams, who built the 2005 World Series champions, has earned an extension through a series of excellent moves. Trades for power-hitting outfielder Carlos Quentin and pitchers Gavin Floyd and John Danks have put the White Sox into the thick of the AL Central race (they led by a half game entering Thursday night's game at second-place Minnesota).

Reinsdorf, in a more controversial move last September, gave White Sox manager Ozzie Guillen a four-year extension through the 2012 season at the end of a disappointing campaign.

It seems to be the season to extend baseball's better GMs. Red Sox GM Theo Epstein reportedly has an agreement for a three-year deal, Mets GM Omar Minaya has an agreement for a four-year extension and Brian Cashman has an offer to return to the Yankees, though in Cashman's case, dollars haven't been discussed and Cashman hasn't even said he yet whether he wants to return.

While most baseball people believe Cashman will return to the team that's employed him his entire 20-year career, the Mariners are believed interested in hiring him and several other teams would seek him as well if he decides not to stay with the Yankees.
