CHICAGO -- The White Sox fired Pedro Grifol, who finished his first career managerial stint with an 89-190 record. The move came on Thursday’s off-day, prior to this weekend’s Part 2 of the Crosstown Classic featuring two games against the Cubs at Guaranteed Rate Field. Bbench coach Charlie Montoyo, third-base coach Eddie Rodriguez and assistant hitting coach Mike Tosar were also fired.

Grady Sizemore, who was on the staff as a Major League coach, was named interim manager for the remainder of the 2024 season, and the team announced a search for a new full-time manager is underway and a replacement will be named after the season.

“As we all recognize, our team’s performance this season has been disappointing on many levels,” said White Sox senior vice president/general manager Chris Getz in a statement. “Despite the on-field struggles and lack of success, we appreciate the effort and professionalism Pedro and the staff brought to the ballpark every day. These two seasons have been very challenging. Unfortunately, the results were not there, and a change is necessary as we look to our future and the development of a new energy around the team.”

Grifol replaced Miguel Cairo, who had replaced Hall of Famer Tony La Russa late during the 2022 season as La Russa battled through health issues. Grifol won the interview process, according to then-general manager Rick Hahn, with Grifol being picked out of 30 original candidates.

But the White Sox and Grifol won truly little after that point. His managerial career started with a 3-2 victory over the defending World Series champions in Houston on March 30, 2023, but by the end of April, the White Sox already had dropped to 8-21 and needed a seven-run ninth-inning rally at home against the Rays to secure that eighth victory on the final game of April.

His first season finished at 61-101, but fortunes didn’t improve for Grifol or the White Sox in ’24 under Getz. The White Sox struggled to a 3-22 start, endured a 14-game winning streak from May 22 to June 6, and then went through a franchise-record and American League record-tying 21-game losing streak that ended Tuesday night in Oakland.

The White Sox have a 28-89 record overall, a 1-18 mark since the All-Star break and an 11-49 record on the road.

Young players such as starters Jonathan Cannon and Ky Bush and infielders Brooks Baldwin and Lenyn Sosa will get a significant look through the end of the season. That group could increase through Minor League callups over the final two months.
