The Chicago White Sox fired front office executives Ken Williams and Rick Hahn Tuesday, moving on from the longtime leadership pairing amid another disappointing season.

Williams had been Chicago’s executive vice president for 11 seasons after previously serving as the club’s general manager for 12 years. Hanh took over the GM role when Williams was promoted in October 2012.

The club announced the change in leadership by releasing a statement on social media, ending a disappointing era for the White Sox, who entered play Tuesday in fourth place in the AL Central with a 49-76 record.

The White Sox have not won a postseason series since their World Series title in 2005 and have made just three playoff appearances in that span.

“This is an incredibly difficult decision for me to make,” White 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.”

The club said in the statement that the search for a new head of baseball operations will begin immediately, and the White Sox hope to fill the position before the end of the season.

Jeremy Haber and Chris Getz served as assistant general managers under Hahn, but the White Sox did not say if internal candidates would be considered for promotion.

Chicago snapped an 11-year playoff drought in 2020 and followed by winning the Central with a 93-69 record in 2021.

Several key contributors from that 2021 squad moved on to other teams, while others – such as Tim Anderson and Yoan Moncada – have since regressed.

The result was an 81-81 season last year and a disastrous 2023 season that is on pace for 98 losses.

This year’s team got out to a 7-21 start – including a 10-game April losing streak – and never made a serious run to get back into playoff contention.
