Twins Call Up Top Prospect Kaelen Culpepper for MLB Debut Against Brewers

The Minnesota Twins are turning to the farm system for a jolt of energy. The club is promoting Kaelen Culpepper, its No. 2 overall prospect, to the major leagues ahead of this weekend’s series against the Milwaukee Brewers, according to multiple reports on Friday. The move brings one of baseball’s most anticipated infield prospects to the Twins roster for the first time, and it comes as Minnesota searches for offensive answers down the stretch.

Culpepper, 23, was Minnesota’s first-round pick in the 2024 MLB Draft, taken 21st overall out of Kansas State, where he was a three-time All-Big 12 selection. He signed for a slot-value bonus north of $3.9 million and wasted little time climbing the organizational ladder, reaching High-A that same summer before working his way through Double-A Wichita in 2025 and settling in at Triple-A St. Paul for a full season in 2026. MLB Pipeline ranks him as the Twins’ No. 2 prospect and among the top 30 to 40 prospects in the sport, a reflection of a hit tool and speed-power combination that scouts have graded as above-average across the board.

A Breakout Triple-A Season Despite an Injury Setback

The path to this call-up wasn’t without a hiccup. Culpepper battled a glute strain that sidelined him for close to two months in the middle of the summer, temporarily slowing his push toward Target Field. Since returning to St. Paul’s lineup in late July, though, he’s been arguably the hottest hitter in the organization, going 11-for-40 over his first 10 games back. For the season, Culpepper is slashing roughly .271 with an OPS pushing .870, adding 14 home runs, more than 40 RBI, and 15-plus stolen bases in fewer than 75 Triple-A games — a power-speed profile that’s been near the top of the International League leaderboard all year.

Defensively, Culpepper has spent most of his time at shortstop this season while also getting reps at second and third base, giving the Twins some positional flexibility as they figure out exactly how to deploy him at the big-league level. That versatility could matter immediately, with Minnesota needing a spark in a lineup that’s cooled off in recent weeks.

Why the Timing Matters

The call-up arrives after the Twins let the trade deadline pass without a major addition, leaving the roster largely as-is for the stretch run. Promoting Culpepper now, rather than in September, signals the front office sees him as more than a courtesy look — it’s a real opportunity to audition for a role during a period when the big-league lineup has scuffled. Minnesota has gotten uneven production from its infield in recent weeks, and Culpepper’s calling card in the minors has been the kind of on-base-plus-thump combination that can lengthen a lineup. Analysts covering the Twins system had grown increasingly vocal in recent weeks that there was no longer a reason to keep him in St. Paul once he proved his glute strain was fully behind him, and Friday’s move effectively answers that pressure.

What Comes Next for the Twins’ Top Infield Prospect

Culpepper’s promotion caps a stretch that had become one of the more discussed storylines in the Twins’ system, with fans and analysts pushing for weeks for the club to give its top infield prospect a look. He now joins a Minnesota roster that’s leaning on its pipeline for a boost as the season winds toward its final stretch, and his blend of on-base ability, pop, and speed gives the Twins a different kind of weapon than what’s currently on their bench. If Culpepper can carry any of his Triple-A production into the majors, his exact role in the infield mix — and whether the Brewers series is the start of an extended big-league stay — should become clear quickly.

Culpepper isn’t guaranteed an everyday role right away, but his versatility across shortstop, second, and third base gives Minnesota’s coaching staff multiple ways to work him into the mix without disrupting the rest of the infield. For a player who was one of the most hyped college bats in the 2024 draft class, reaching the majors in barely two years is a fast track — and a sign the Twins believe his bat is ready for a bigger stage than St. Paul can offer. How he handles major-league pitching in his first look will go a long way toward shaping Minnesota’s infield plans for the rest of the season and beyond.
