Mitch Garver retires after parts of ten MLB seasons with Twins, Rangers, and Mariners

Mitch Garver, the catcher whose 2019 breakout made him one of the more dangerous bats in a Minnesota lineup that called itself the Bomba Squad, has reportedly retired from baseball. Ted Schwerzler of minnesotasportsfan.com first reported the news, with Darragh McDonald of MLB Trade Rumors relaying it. The retirement closes a career that spanned parts of ten major league seasons across three franchises.

What happened

Per the report, Garver stepped away from playing after a career that took him from the University of New Mexico — where the Twins selected him in the ninth round of the 2013 draft — through stops in Minnesota, Texas, and Seattle. He made his major league debut in 2017 and, by the time his career concluded, had established himself as one of the more productive offensive catchers of his era when healthy enough to take the field.

The path was rarely smooth. Garver's career was threaded through with injuries that repeatedly interrupted what might otherwise have been longer, more statistically complete seasons. That tension — between genuine offensive ability and the physical toll of the position — defined much of his time in the league.

Why it matters

Garver's career is a useful lens on what teams ask of catchers and what catchers ask of their bodies. The position is the most physically demanding on the field, and Garver's résumé reflects that reality: a series of seasons in which the production, when it came, was excellent, and the absences were frequent.

His 2019 season remains the headline. Playing in only 93 games and stepping to the plate just 359 times, Garver launched 31 home runs as part of Minnesota's Bomba Squad. His .273/.365/.630 slash line that year translated to a wRC+ that was 55% better than league average, per MLB Trade Rumors. The 2019 season has since become well-documented for its league-wide home run environment — McDonald notes that many home run records were set across the league that year — but Garver's production stood out even within that context.

The skepticism that followed him out of the minors centered on his defense. The Twins were uncertain enough about his ability to stick at catcher that his path to a 40-man roster spot required patience; by the end of 2016, the club was optimistic enough to protect him from the Rule 5 draft by adding him to the 40-man. Under general league mechanics, a player not on the 40-man is eligible to be selected by another club in that draft, so the decision to protect Garver reflected a real organizational commitment. His bat ultimately made the defensive questions secondary, though they never fully disappeared.

The numbers

Garver's career unfolded in distinct chapters. His debut in 2017 produced a .196/.288/.348 line in 52 plate appearances — modest enough that a different organization might have moved on. The following season brought seven home runs and a .268/.335/.414 line, a meaningful step forward. Then came 2019.

After the shortened 2020 season — in which an intercostal strain limited him to 23 of the club's 60 games and his production suffered — Garver returned in 2021 to hit 13 home runs in 243 plate appearances, posting a .256/.358/.517 line and a 139 wRC+. The offensive quality was there; the availability was not.

His best season in Texas came in 2023. Despite a lengthy absence for a knee sprain, Garver hit 19 home runs over 344 plate appearances, drew walks at a 12.8% clip, and slashed .270/.370/.500 — a line that translated to a 142 wRC+. That production arrived at useful timing: per MLB Trade Rumors, the Rangers made the playoffs that year, though the source as transmitted does not complete that sentence.

His 2022 season in Texas, his first after the trade from Minnesota, was interrupted by flexor tendon surgery in July after only 54 games. The surgery came mid-season; the recovery carried into 2023.

Where the club stands

The Twins, who drafted Garver and developed him through the system, finished the season at 77-85 (.475), sitting third in the AL Central, 8 games back, and have been eliminated from both the division race and the Wild Card race. The club's Wild Card ranking sits at 7, 7.0 relative to the cut line. Minnesota enters this news on a one-game winning streak — which, given the broader context of a season that ended 8 games out of the division lead, is the kind of streak the front office is probably filing under "encouraging sign for next year."

The Twins have also been active on the coaching staff in recent days, with the club naming Brian Reith as their new pitching coach.

How did Garver end up in Texas?

The emergence of Ryan Jeffers gave the Twins the organizational depth to move Garver before the 2022 season. Per MLB Trade Rumors, he was traded to the Rangers for Isiah Kiner-Falefa and Ronny Henriquez. The transaction had an immediate ripple: the very next day, per the report, Kiner-Falefa was dealt to the Yankees as part of a package that also included Josh Donaldson and Ben Rortvedt, with Gary Sánchez and Gio Urshela heading the other direction. Garver's departure from Minnesota thus set off a chain of moves that reshaped rosters on both sides of the league.

His time in Seattle, the third stop in his career per the report, is not detailed further in the available reporting.

What we don't know yet

The report, as relayed by MLB Trade Rumors, does not include a statement from Garver himself, a specific date for the retirement, or any detail about what comes next for him. The report does not specify the circumstances of his time with the Mariners or how that chapter concluded. Whether the retirement is accompanied by any formal club or league acknowledgment has not been reported.

The report also does not address whether Garver's decision was driven by a specific injury, a broader assessment of his health, or simply a personal choice to step away. Given the number of times injuries shaped his career, the question is a natural one — but the material does not answer it, and the desk does not speculate.

What to watch

For the Twins, the retirement of a player they drafted, developed, and eventually traded is a footnote to a rebuilding offseason rather than an active roster question. With Ryan Jeffers entrenched at catcher and the club finishing at 77-85, Minnesota's attention will turn to the offseason and what the front office does with a roster that finished 8 games out of the division lead.

The broader story Garver's career tells — about the difficulty of staying healthy at catcher, about the gap between peak offensive production and games played, about what a 31-homer season in 359 plate appearances might have looked like over a full year — is the kind of thing that will follow his name into whatever retrospective treatment his career eventually receives. The 2019 Bomba Squad already has a certain nostalgic glow in Minnesota. Garver was a real part of it.

Per Ted Schwerzler of minnesotasportsfan.com, that chapter is now closed.
