Brad Ausmus, former manager of the Detroit Tigers and the Los Angeles Angels, has been hired as bench coach for the Oakland Athletics, providing some much-needed experience to the coaching staff of rookie manager Mark Kotsay.

The A's finalized Kotsay's coaching staff on Friday, also announcing the promotion of Tommy Everidge to major league hitting coach and the hiring of Chris Cron as an assistant hitting coach.

Ausmus, 52, managed the Tigers from 2014 to 2017, winning the American League Central Division at the beginning of that four-year stretch and finishing with a 314-332 regular-season record. The longtime major league catcher then went 72-90 in his only season as the Angels' manager in 2019, a year tarnished by the sudden death of young pitcher Tyler Skaggs.

Everidge, 38, has spent the last eight years as a hitting coach in the A's farm system and was originally drafted by the team in 2004. Cron, the father of Colorado Rockies first baseman C.J. Cron, spent the last eight years in the Arizona Diamondbacks' minor league system, most recently as the organization's field coordinator, and has compiled two decades' worth of managing experience in the minor leagues.

The hirings prompted Darren Bush to move from hitting coach to third-base coach and Eric Martins to move from assistant hitting coach to first-base coach. Mike Aldrete will transition from first-base coach to quality control coach. Kotsay, 46, spent the last six years on the A's coaching staff and was hired over the offseason to replace Bob Melvin as the team's manager. The A's allowed Melvin to opt out of the final year of his contract to join the San Diego Padres.
