Projection systems are not in the business of hype. They are cold, calculating, and often conservative. That’s what makes it so interesting when one of them plants a flag on a player who has barely cracked the upper minors. FanGraphs’s ZiPS has done exactly that with Kaelen Culpepper.
The Twins likely don’t agree with ZiPS’s plan to promote him aggressively in 2026. It seems more likely that they’ll roll with Brooks Lee at shortstop. But after a dynamite first full professional season, the Twins’ 2024 first-rounder has quickly become one of the system’s favorites, and that’s no accident.
A Massive Step Forward
Culpepper took a massive step forward last season, showing he can impact the game with his bat while sticking at shortstop. In 113 games, he posted a 138 wRC+ with 25 steals, flashing both on-base ability and speed. The organization named him its Minor League Player of the Year, and he enters 2026 as a consensus top-100 prospect.
ZiPS noticed. He was among MLB’s biggest ZiPS gainers for 2026, a list that includes Aaron Judge and Yordan Alvarez. A year ago, he was projected for just 0.3 fWAR. Now he sits at 1.9 fWAR, were he to get a full year’s worth of playing time. That’s a substantial jump for a player who has yet to play at Triple-A. To reach that 1.9 fWAR mark, ZiPS projects Culpepper for 510 plate appearances in 2026. Obviously, that’s essentially a default number, to give a sense of what a full season would look like from him. He’s unlikely to play that much at Target Field this year. If he did, though, the model thinks he’d be perfectly serviceable.
The offensive line is modest on the surface. ZiPS projects a 94 wRC+ and a .376 slugging percentage, pointing to a lack of present power. But there is value baked in elsewhere. He’s projected for a .305 wOBA, positive defensive value, and enough overall contribution to be an above-average regular.
His player comparisons are not superstar names: Bill Spiers. Howard Freigau. Ricky Adams. Those comps speak to versatility and steady value, more than flash. ZiPS isn’t projecting stardom right now. It just shows promise, with room to grow. That’s where it gets interesting.
The Defense Debate
The Twins front office believes Culpepper improved his overall outlook with defensive gains last season. That belief is reflected in the positive defensive projection.
“His makeup and his leadership on the field, the way he goes about his work, have all been exactly what we’ve been looking for,” Twins GM Jeremy Zoll said.
The arm strength is there. The internal reviews are strong. But not everyone is convinced he sticks at shortstop long term.
Baseball America’s JJ Cooper has expressed skepticism about Culpepper’s ability to remain at the position. While he has the arm, some evaluators question his range and actions. Many scouts believe he may ultimately slide to third base.
That positional uncertainty matters, because the offensive bar changes depending on where he plays. A 90 OPS+ with solid defense is more palatable at shortstop than at third base. ZiPS, at least for now, is betting that the glove will be good enough.
A Complicated Shortstop Picture
The Twins’ shortstop depth chart adds another wrinkle. Lee is expected to open the season as the starter. The team added a veteran backup option, Orlando Arcia, to provide depth and stability. On paper, there is no everyday job available for Culpepper.
But depth charts have a way of unraveling. One injury to a significant player could change the equation quickly. If Lee misses time or struggles offensively, Culpepper could force the issue. Whether it’s Lee, Royce Lewis or Luke Keaschall, a major injury to any of the injury-prone infielders slated to start could crack the door for Culpepper. For that matter, Lee is projected for a lousy 84 wRC+ and worse defense than Culpepper, so if you ask ZiPS, the Twins should simply escalate the young player past the incumbent right now.
The Twins haven’t been shy about promoting prospects who prove ready. Culpepper may not need much Triple-A seasoning. Minnesota saw this in 2025, with Luke Keaschall playing only 28 games at Triple-A before his promotion.
The Offensive Ceiling
Culpepper is not a finished product offensively. He can be prone to chasing off-speed pitches out of the zone. That approach will be tested at higher levels. But there were encouraging signs, too. He walked 50 times and struck out just 90 times, showing better swing decisions than some evaluators expected.
He also reached the 20-home run mark, despite posting the system’s third-highest groundball rate. That’s significant. If he can learn to elevate consistently, there’s more power in the profile than the current projections imply. That’s part of why ZiPS is optimistic. The system sees a player who already produces value and has room to grow if the batted-ball profile improves.
Why You Can Love Him, Too
Culpepper profiles as an above-average regular with All-Star upside at an infield spot still to be determined. That kind of player doesn’t need to be a franchise cornerstone to be immensely valuable. He’s played just 139 minor-league games and has yet to face Triple-A pitching. On the surface, it might feel aggressive to expect a big-league debut this season.
It’s not unrealistic, though. If Culpepper keeps hitting as he did in 2025, the Twins will have no choice but to give him a look at the major-league level. ZiPS already believes he can handle a near-everyday role. Now, it becomes a matter of timing.
Projection systems don’t often fall in love. When they do, it’s worth paying attention. ZiPS loves Culpepper. You probably should, too.
