Daryl Boston, Jose Castro out as White Sox coaches

Hitting coach Jose Castro and first-base coach Daryl Boston will not return to White Sox manager Pedro Grifol’s staff in 2024, according to multiple sources.

Assistant hitting coach Chris Johnson, who was on the job for one season after a promotion from Triple-A Charlotte, and bullpen coach Curt Hasler have been offered jobs on Sox’ minor league side of operations.

The Sox made these moves official on Friday.

Boston, 60, who also worked with Sox outfielders, was a holdover from multiple staffs before Grifol and was the longest-tenured Sox coach. A close friend of former executive vice president Ken Williams, who was fired in August, Boston served 11 seasons as first-base coach and 26 overall in the organization.

Castro, 65, was the Braves’ assistant hitting coach before joining Grifol’s staff this season. Sox hitters were said to be torn between multiple hitting voices on the staff. Major-league field coordinator Mike Tosar also worked with hitters.

Pitching coach Ethan Katz, 40, a holdover from former manager Tony La Russa’s staff, is expected to return for his fourth season.

The Sox were last in MLB in on-base percentage, 29th in runs scored, 20th in homers and had the highest chase rate on pitches out of the strike zone during a 61-101 season, one of their worst ever.

“When you talk about the staff, you talk about people that have been here for a long, long time,” Grifol said Sunday. “Unfortunately, this is a game that’s predicated on wins and losses, so obviously, every year, this is a tough time of the year for staff.”
