I Regret to Inform You That Trevor Larnach is Still Not a Good Defensive Left Fielder

Eighty-six games into the 2026 MLB regular season, Trevor Larnach has started 58 games in left field for the Minnesota Twins, accounting for roughly 68% of starts at the position. At first glance, this development comes as a moderate surprise. Entering the season, Larnach wasn’t expected to occupy a full-time role at either corner outfield spot, evidenced by him splitting time in left with platoon partner Austin Martin and Matt Wallner being the full-time right fielder early this spring.

 

Yet, given Wallner’s demotion to Triple-A, Martin’s subsequent move to right field (and eventual demotion back to a bench bat), and the organization’s younger, inexperienced corner outfield options (Alan Roden, Gabriel Gonzalez, Emmanuel Rodriguez, Walker Jenkins, and Hendry Mendez) not yet receiving extended opportunities in the majors, Larnach has become the club’s full-time left fielder.

 

Circumstance isn’t the only reason for Larnach’s unexpected full-time role. Hitting .288/.381/.437 (good for a 131 wRC+), the 29-year-old has become a meritorious mainstay, often hitting in the upper third of the club’s lineup. He's become an irreplaceable part of Minnesota’s ability to succeed this season offensively. That being the case, he's received extended opportunities in the field. Unlike his sustained success at the plate, however, Larnach hasn’t improved defensively, despite how hard those in the Twins.TV broadcast booth try to persuade you otherwise.

 

Over 139 attempts in left field, Larnach has -4 Outs Above Average (OAA), tying him for the second-lowest rating at the position alongside Isaac Collins and Yohendrick Piñango. Larnach’s downfall, in particular, is that he struggles getting to balls hit both to his left and right. He’s serviceable on balls hit in front of and behind him. However, the quality of a corner outfielder comes in their ability to chase down balls in the gaps and corners. Larnach struggles at both.

 

Let’s take a look at some examples.

 

What do you think the catch probability was of this ball? Close your eyes and think about it for a second before continuing to read this piece. Okay—are you ready? Have you regrouped? Okay, it was 99%. Larnach had 4.1 seconds to travel the 48 feet necessary to catch that ball. Instead, he stood flat-footed for multiple seconds as the bloop off Max Muncy’s bat traveled through the air before landing for a single. That’s not what a plus fielder does, Cory Provus!

Let’s take a look at a more challenging ball put into play.

 

Let’s play the same game. Close your ey—It had a 95% catch probability. Larnach had 5.4 seconds to travel the 68 feet necessary to catch the ball hit off rookie icon Kevin McGonigle’s bat. Instead, he took a poor route and misplayed, allowing McGonigle to cruise into second with a double. That's not what an improved left fielder does, Justin Morneau!

Finally, let’s take a look at a play that appears incredible, but should have been much less dramatic.

The ball hit by Sam Antonacci had a 55% catch probability, with Larnach trekking 82 feet in 4.9 seconds to make the catch. Again, this was a nice play by the long-time Twin, and he deserves credit for making the tough catch. That being said, more instinctive and faster left fielders would have gotten under that ball, removing the theatrics entirely. 

Larnach is slightly faster this season, improving from a 26.1 ft/sec sprint speed in 2025 to 26.9 ft/sec. It is also true that his arm value and strength have improved mightily in 2026. Still, he’s clunky, often getting poor jumps and failing to reach balls hit to his left and right that average left fielders catch with ease. Again, Larnach has been a nice surprise at the plate for the Twins this season, but we need to stay measured. He isn’t a good defensive left fielder. In fact, he’s one of the worst in the league. That's not ragging on a player trying to forge a lasting role and reach paydirt in free agency; it's just the reality we have to reckon with.
