White Sox clean house in front office, firing GM Rick Hahn and executive VP Ken Williams

CHICAGO — The Chicago White Sox have relieved executive vice president Ken Williams and general manager Rick Hahn of their responsibilities effective immediately, the team announced Tuesday.

“This is an incredibly difficult decision for me to make because they are both talented individuals with long-term relationships at the White Sox,” Sox Chairman Jerry Reinsdorf said in a statement. “Ken is like a son to me, and I will always consider him a member of my family. I want to personally thank Ken and Rick for all they have done for the Chicago White Sox, winning the 2005 World Series and reaching the postseason multiple times during their tenures. I have nothing but the greatest respect for them as people and appreciate the commitment and passion for the White Sox they exhibited over the years.

“Ultimately, the well-worn cliche that professional sports is results-oriented is correct. While we have enjoyed successes as an organization and were optimistic heading into the competitive window of this rebuild, this year has proven to be very disappointing for us all on many levels. This has led me to the conclusion that the best decision for the organization moving forward is to make a change in our baseball department leadership.”

The Sox are in a the midst of a dismal season. Hoping to rebound from an 81-81 record last season, they are in fourth place in the American League Central with a 49-76 record entering Tuesday.

In the release announcing the news, the Sox said they will “begin a search for a single decision maker to lead the baseball operations department” and anticipate having someone in place “by the end of the season.”
