Following the departure of hitting coach Brant Brown, who’s set to join the Mariners’ coaching staff, the Marlins have promoted assistant hitting coach John Mabry to lead hitting coach, reports Christina De Nicola of MLB.com. Miami has also hired former American League batting champion Bill Mueller as its new assistant hitting coach.
Mabry, 53, enters his second season on the Marlins’ coaching staff and his 12th year as a big league coach overall. A veteran of 14 Major League seasons who batted .263/.322/.405 from 1994-2007, Mabry joined the Cardinals’ coaching staff as an assistant hitting coach in 2012 and was later promoted to lead hitting coach in St. Louis as well — a role he held until the 2018 season. He also spent three years on the Royals’ staff prior to joining the Fish. He and Marlins skipper/2023 NL Manager of the Year Skip Schumaker were teammates with the Cards during Schumaker’s rookie season in 2005.
The 52-year-old Mueller will return to a big league dugout for the first time since 2018 — the final of his four seasons as Cardinals’ assistant hitting coach. He overlapped with Mabry throughout that entire tenure, so the two have plenty of familiarity with one another and a strong working relationship. More recently, Mueller worked with the Nationals’ player development department from 2022-23, and he’s also spent time as a special assistant and scout with the Dodgers in addition to a one-year run as the Cubs’ hitting coach in 2014. In parts of 11 seasons from 1996-2006, Mueller batted .291/.373/.425. He won a World Series with the 2004 Red Sox and won a Silver Slugger with Boston in 2003, when he hit .326/.398/.540 en route to that aforementioned AL batting crown.
