The Mariners plan to hire Kevin Seitzer as hitting coach, reports Daniel Kramer of MLB.com. Edgar Martinez, who finished last season in that capacity, will remain with the M’s in an overarching role. Kramer writes that Seitzer will report to Martinez, so it seems the franchise icon is still the team’s lead hitting voice. Martinez is not expected to regularly travel with the team on road trips, though he’ll be involved at Spring Training and during the majority of the club’s home games. Adam Jude of the Seattle Times tweets that Martinez’s official title will be senior director of hitting strategy.
Additionally, Kramer reports that the M’s are hiring Bobby Magallanes as assistant hitting coach. The 55-year-old spent the last four seasons working under Seitzer as an assistant hitting coach with the Braves.
Seitzer brings two decades of hitting coach experience to Dan Wilson’s staff. He’d worked in that capacity with the Diamondbacks, Royals and Blue Jays before being hired by the Braves during the 2014-15 offseason. Seitzer spent 10 seasons as Atlanta’s hitting coach. The Braves have been contenders for most of that stretch.
The development of Ronald Acuña Jr., Austin Riley, Ozzie Albies and Michael Harris II into star players has obviously been an instrumental part of the Braves’ success. Seitzer was fortunate to work with a lot of talented hitters, but he certainly deserves some amount of credit for overseeing a lineup that trails only the Dodgers in scoring over the last five seasons.
Still, the 2024 campaign was a mixed bag. The Braves’ offense floundered for a few months after Acuña’s season-ending knee injury. They finished the year 15th in scoring with a .243/.309/.415 team batting line. They were in the top 10 in slugging but right in the middle in both batting average and on-base percentage. That was below expectation for a team with as much star power as the Braves possess. Atlanta fired Seitzer, Magallanes, and catching coach Sal Fasano shortly after being eliminated from the playoffs.
It’s the latest shakeup to Seattle’s hitting infrastructure. The Mariners have struggled for years to field even a league average offense, which would probably be sufficient to get to the postseason given the strength of their starting pitching. The M’s hired Brant Brown as offensive coordinator last offseason. They fired him two months into the season in an effort to spark the lineup. That didn’t work, and the M’s dismissed hitting coach Jarret DeHart along with skipper Scott Servais three months later. Assistant hitting coach Tommy Joseph left the team at the end of the season to take the same position with the Orioles.
Martinez joined the staff when his longtime teammate Wilson signed on as manager. He had previously been reluctant to assume a full-time coaching position because of family considerations. It seems they’ve settled on an unconventional role that’ll allow Martinez to remain actively involved without spending much time away from Seattle.
