The White Sox announced they've officially relieved first base coach Daryl Boston and hitting coach José Castro. They also announced they have offered positions in their developmental system to bullpen coach Curt Hassler and assistant hitting coach Chris Johnson.
Boston, who rolled over from the previous coaching staff into Pedro Grifol's, has been with the White Sox for 26 years. In 2013, then-manager Robin Ventura made him the team's first base coach, a post he kept for 11 years.

Castro, 65, spent just one season with the White Sox. Before this season, he spent the last eight seasons with the Atlanta Braves as the team's assistant hitting coach.
As for the reassignments, here are their backgrounds.
Johnson, 39, was named the hitting coach for the Triple-A Charlotte Knights before the 2021 season. In November of 2022, he made his way up to the major league as the Sox' assistant hitting coach.
Hassler has been with the White Sox for over 30 years. He started with the club in 1992 as a pitching coach for the organization's Rookie and Single-A classes. In 2017, he made his first appearance --- as a coach --- in the big leagues under Rick Renteria. He's been the team's bullpen/assistant pitching coach since then.
