Justin Jirschele (Triple-A Charlotte), Sergio Santos (Double-A Birmingham), Guillermo Quiroz (Advanced-A Winston-Salem), Patrick Leyland (Class A Kannapolis) and Danny González (Arizona Complex League Sox) will serve as the White Sox’ minor league managers in 2024, the club announced Friday.
Jirschele, Quiroz, Leyland and González all return to their posts following last season. Santos, a former Sox relief pitcher from 2010-11, managed two seasons in the Yankees system, including Advanced-A Hudson Valley in 2023.
Coordinators returning include Doug Sisson (field), Matt Zaleski (pitching), Ryan Newman (infield) and Julio Mosquera (catching). Former bullpen coach Curt Hasler joins Donnie Veal as assistant pitching coordinators.
Alan Zinter is the new hitting coordinator. Pat Listach will be bench coach and R.C. Lichtenstein the pitching coach at Charlotte.
Simeon grad Darius Day, who played in 169 minor league games, will make his professional coaching debut as bench coach with Winston-Salem. Day is a graduate of the White Sox Amateur City Elite program.
Paul Janish enters his first year overseeing the organization’s minor-league operations and player development system.
“Our entire staff has been working all off-season to ensure our players will be ready to hit the ground running for mini camps, spring training and into the regular season,” Janish said. “The ultimate goal remains to have our players prepared and ready to contribute at the major-league level, and we believe this staff is well equipped to help all of our players reach his full potential.”
