Mariners Release Mitch Haniger – MLB Trade Rumors

The Mariners announced this morning that they’ve released outfielder Mitch Haniger. Haniger was owed $15.5MM this season, the last year of the three-year, $43MM contract he signed with the Giants prior to the 2023 season. Both Haniger himself and president of baseball operations Jerry Dipoto provided statements alongside the announcement.

“Mitch has been a significant part of Mariners history and will be missed,” Dipoto said in the statement. “The day he arrived for his first spring training back in 2017, he established himself as one of the most focused, prepared, and hardest working players I’ve ever been around. We all appreciate the many ways he’s made us all better, on the field and off.”

“Putting on a Mariners uniform and playing at T-Mobile Park is something I’ll cherish forever,” Haniger said in his statement. “To our fans, my teammates, and everyone a part of this organization, thank you for embracing my family and me. We have so many great memories to look back on.”

It’s an unfortunate ending to Haniger’s tenure with the organization, which first began during the 2016-17 offseason when the Mariners acquired him from the Diamondbacks alongside Jean Segura and Zac Curtis in a deal that sent Ketel Marte and Taijuan Walker to Arizona. While Diamondbacks fans surely remember that deal fondly as Marte has grown into a star player with the club, Haniger enjoyed an impressive career of his own with Seattle over the years. Though he was often dogged by injuries throughout his tenure with the club, the outfielder remained productive and slashed .263/.337/.480 with a 124 wRC+ in 530 games from 2017 to 2022. His most impressive campaign with Seattle came in 2018, when he delivered a 137 wRC+ en route to a 5.0 fWAR/6.5 bWAR season that earned him an All-Star appearance and an eleventh-place finish in AL MVP voting that year.

Haniger departed the club for free agency following the 2022 campaign, and found a lucrative deal in San Francisco that guaranteed him $43MM over three years. Unfortunately, his first season with the Giants was one to forget as the outfielder was limited to just 61 games where he slashed a paltry .209/.266/.365 in 229 trips to the plate. Haniger was bit by the injury bug repeatedly through that season, as he suffered a fractured forearm in addition to oblique and back issues throughout the year. Despite those injuries, the Giants opted not to keep him in the fold and find out what a healthy season from their new outfielder might look like.

Instead, they shipped him back to Seattle alongside right-hander Anthony DeSclafani last winter in a deal that sent Robbie Ray to San Francisco. The surprise blockbuster reunited Haniger with the Mariners, and as he entered the season much healthier than he was the year prior there was plenty of reason for optimism that the veteran could return to form with the club. Unfortunately, that did not come to pass. Haniger struggled through 121 games with Seattle last year, slashing just .208/.286/.334 in 423 plate appearances.

It was his second consecutive season with negative WAR, and a career-high 29.8% strikeout rate offered little reason for optimism that he would be able to turn things around going forward. Haniger’s odds of recapturing his past success in Seattle further shrunk when the club acquired Randy Arozarena and Victor Robles during the 2024 season, both of whom effectively have the outfield corners locked down headed into 2025.

Haniger entered camp this year in competition with Mitch Garver and non-roster invitee Rowdy Tellez for the starting DH job, but quickly fell behind the club’s other two options when he hit just .167/.250/.389 across seven games this spring before being sidelined by shoulder soreness. He hasn’t played in a game since early March, and while a stint on the injured list appeared possible it now seems that the Mariners will instead allow Haniger to pursue opportunities elsewhere while clubs around the league are still finalizing their Opening Day roster decisions. Expecting a significant bounceback from a 34-year-old who is two full seasons removed from being an above average hitter would be a risk, but there’s little harm in another club seeing what Haniger might have left on a minor league deal should he be interested in one.
