3 Up, 3 Down: Kaelen Culpepper

Kaelen Culpepper's first taste of the big leagues provided plenty for Twins fans to evaluate. The 2024 first-round pick spent most of the season at Triple-A before making his MLB debut, and while his time in Minnesota was limited to 33 games, he showed several tools that could make him an important part of the organization's future.

Culpepper's debut was not perfect. There were some obvious holes in his offensive game, particularly against breaking pitches, but there were also signs that his physical tools can translate to the highest level. Here are three things that stood out in a positive way—and three areas Culpepper will need to improve.

Up 1: Legit Arm Strength

Culpepper's arm strength was touted dating back to his college days, but Twins fans got to see that tool on full display this season. He posted an 88.5-MPH average arm strength, placing him in the 77th percentile among MLB infielders. That's an important tool for a player who could potentially move around the infield during his career, but its significance is particularly obvious while he's playing the most demanding spot on the dirt.

If Culpepper eventually has to move to third base, his arm could help make that transition much easier. Shortstop is still the most natural fit for him, but having legitimate arm strength gives the Twins additional flexibility as they determine where he fits best long term.

Up 2: Bat Speed

Culpepper's bat speed was another tool that immediately stood out during his debut. He averaged 73.7 MPH of bat speed, a figure that would have ranked in the top 30% of big-leaguers had he accumulated enough plate appearances to qualify. That's an encouraging sign for a young hitter who was not afraid to attack pitches during his first exposure to big-league pitching.

Culpepper's aggressive approach can lead to some swing-and-miss, but the underlying bat speed gives him the ability to do damage when he squares up a pitch. The next step will be turning that raw bat speed into more consistent quality contact.

Up 3: Baserunning

The Twins need more athleticism throughout their roster, and Culpepper is part of a young wave of players who can provide it. Even with only 33 games under his belt, Culpepper produced a positive Baserunning Run Value. 

That came despite having a 60th-percentile sprint speed, showing that effective baserunning isn't simply about having elite straight-line speed. Good instincts and aggressiveness can create value on the bases. Culpepper showed signs of doing that during his brief stint in the majors.

Down 1: Hard-Hit Percentage

Culpepper's aggressive swing can produce hard contact, but his Triple-A performance did not carry over completely to the majors. At Triple-A, he posted a 45.5% Hard-Hit rate. That number dropped to 31.1% during his big-league debut. Had he qualified, that figure would have fallen below the league average. There's plenty of reason to believe the number can improve. Culpepper has the bat speed and physical strength to hit the ball hard. The challenge will be making more consistent contact against top-level pitching, while maintaining the aggression that makes his swing dangerous.

Down 2: Walk Rate

Culpepper showed a much better ability to draw walks in the minors than he did against pitchers who could throw strikes at a big-league rate. He posted an 11.4% walk rate at Triple-A this season. That number nearly disappeared in Minnesota, where he walked only six times in 128 plate appearances for a 4.7% walk rate. Culpepper is never likely to be a hitter who piles up walks, and the Twins don't need him to become one. However, he needs to find a middle ground between being aggressive and expanding the strike zone. A higher walk rate would give him more opportunities to utilize his speed and athleticism, while also offsetting some of the swing-and-miss that comes with his aggressive approach.

Down 3: Breaking Down

Breaking pitches were one of the biggest trouble spots for Culpepper during his debut. He did not record an extra-base hit against breaking pitches and posted a .223 expected batting average and .274 expected slugging percentage against them. Those numbers point to an area that opposing pitchers are likely to continue attacking until Culpepper proves he can handle it.

Adjusting to breaking stuff is one of the biggest challenges young hitters face when they reach the majors. Culpepper's bat speed gives him a foundation to make that adjustment, but recognizing spin and staying disciplined against breaking pitches will be critical to his development.

The Bigger Picture

The most important part of Culpepper's 2026 season may be that he got his first extended look at what major-league pitching is going to throw at him. Now, the Twins will get to see how he responds. The physical tools are evident. His arm strength can play at multiple infield positions, his bat speed gives him offensive upside, and his athleticism can add another dimension to the Twins' lineup. The next step is turning those tools into consistent production.
