The Chicago White Sox pitching staff had its best season in years in 2020, thanks mostly to the signing of starter Dallas Keuchel and a young bullpen that turned a team weakness into a strength.
General manager Rick Hahn made the surprising announcement during a teleconference about Renteria’s dismissal. Both were “mutual” decisions according to Hahn.
He said the front office and Sox fans “owe a debt of gratitude” to Cooper, who oversaw the pitching staff that brought the Sox a World Series championship in 2005.
“These things can get a little overshadowed by the managerial change,” Hahn said of Cooper’s departure.
