(WSCR) The White Sox announced today they have promoted Kenny Williams to executive vice president and named Rick Hahn senior vice president/general manager.

Hahn, a Chicago native, has been with the White Sox since 2000 and helped build the 2005 World Series team and 2008 postseason team.

“Rick’s promotion is very well deserved,” White Sox chairman Jerry Reinsdorf said in a statement released by the club.  “He is one of the most respected young executives in baseball today and that reputation is well earned given his relationships with other team executives, players, agents, manager Robin Ventura and our coaches, members of the media and White Sox fans.  Kenny and Rick together have worked very successfully over the past 12 seasons, and I am excited to see this dynamic grow and expand as Rick assumes more day-to-day authority and responsibility while Kenny is allowed to focus even more on macro issues, talent evaluation and long-term planning for the organization.”

Williams, who served as general manager for 12 seasons and has been a member of the team’s front office since 1992, owns the best winning percentage of any general manager in franchise history.

“You cannot say enough about Ken Williams’ value to the Chicago White Sox, his contributions to our success and the passion he brings to the ballpark each and every day,” said Reinsdorf.  “Kenny raised the idea of promoting Rick several years ago, and we all have agreed that this is the right time to increase the scope and range of Kenny’s involvement while he continues to maintain oversight and final approval on major baseball decisions.”

The club also named Howard Pizer senior executive vice president.
