Bill Mueller hired, John Mabry promoted by Marlins

The Marlins will have their fourth different hitting coach in four seasons. With the departure of Brant Brown to the Seattle Mariners, they are going to go internally and promote assistant hitting coach John Mabry to fill Brown's position as the number one guy, MLB.com's Christina De Nicola reported on Friday. Miami has brought in Bill Mueller as the new assistant hitting coach.

Mabry was hired by manager Skip Schumaker last winter and will be entering his second season coaching with the Marlins organization. Mabry briefly played for the Marlins in 2001 and knew of Schumaker from their time together with the St. Louis Cardinals. He shares some of the same hitting philosophies as Brant Brown did. Schumaker also mentioned on Fish Unfiltered that Marlins players gave him input during the search process, so they apparently enjoyed working with Mabry in 2023.

Bill Mueller had an impressive career as a big leaguer from 1996-2006. He was the 2003 AL batting champ and won a World Series title with the 2004 Boston Red Sox.

After retiring, he joined the Dodgers front office as a special assistant to the general manager and then a year later became the Dodgers interim hitting coach.

Just like many members of the Marlins coaching staff, Mueller was a Cardinal at some point in his career. After a stint with Chicago, Mueller headed to St. Louis to become their assistant hitting coach where he worked alongside Mabry until they were fired together midway through the 2018 season.

Most recently, Mueller was with the Washington Nationals as quality control coordinator, part of the Washington's player development staff.

The 2024 Marlins coaching staff looks to be completely filled out barring any unreported departures.
