Twins Video
The Minnesota Twins made a notable move on Monday, trading Chris Paddack and Randy Dobnak to the Detroit Tigers. In doing so, they opened a spot in an already thin starting rotation that has been hit hard by injuries throughout the 2025 season. To fill that void, the club is turning to one of the organization’s most consistent arms from the minor leagues.
According to multiple reports, the Twins are calling up right-hander Pierson Ohl from Triple-A St. Paul. He is expected to make his MLB debut on Tuesday at Target Field, against the Boston Red Sox. Given his usage this season, Ohl will likely work in a bulk role behind an opener, similar to how the team has used Travis Adams earlier this year. Twins manager Rocco Baldelli recently talked about how the team will use bullpen games over the season’s final two months.
Precision Over Power
Ohl, 25, may not be a household name, but he has quietly carved out a reputation for elite command throughout his minor-league career. Drafted in the 14th round out of Grand Canyon University in 2021, he has walked just 3.6% of batters in 389 professional innings. For comparison, the major-league average usually falls in the 8% range.
While he has never been known for overwhelming stuff, Ohl has made meaningful strides this year. He has increased his strikeout rate from 21.6% across his first three seasons to a sharp 30% in 2025. That growth appears tied to adjustments in his arm slot and changeup grip, giving him an added dimension to pair with his pinpoint control.
Climbing the Ladder
Ohl’s journey through the system has been steady, and stayed mainly under the radar. After debuting in the Florida State League, he reached Double-A Wichita in 2023 and posted solid results, with a 2.69 ERA, a 21.8 K%, and a 3.8 BB%. However, a rough 2024 campaign (wherein he finished with a 4.68 ERA) threatened to stall his progress. His strikeout rate dipped to 16.3% and batters were hitting the ball harder against him, with a 7% increase in their line-drive rate. He made the adjustments described above following the season, and the results speak for themselves.
Rather than plateau, Ohl responded in 2025 with his best season yet. He owns a 2.17 ERA across 66 1/3 innings spanning High-A, Double-A, and Triple-A. He has struck out 79 hitters and walked only 10 during that stretch. Though most of his work this season has come in multi-inning relief appearances, he has made five starts and maintained consistent effectiveness, regardless of role.
The Twins have used him in a swingman role this season, with outings ranging from just under two innings to a high of four innings. The Twins have made a conscious pitching development plan with players like Ohl to get them more consistent work in shorter outings. That makes him a good fit for a hybrid spot start, which is likely how the Twins will deploy him on Tuesday.
Ohl utilizes a six-pitch mix, but is highly reliant on a fastball-changeup combination. He uses his fastball 40% of the time (92.1 mph) and his changeup over 38% of the time (81.1 mph). His other offerings include a cutter (85.7 mph), slider (83.4 mph), curveball (77.8 mph), and sinker (92.4 mph). Depending on his role with the Twins, it seems likely for him to continue to lean on his fastball and changeup, especially in his big-league debut.
Filling the Gaps
Minnesota’s rotation is currently missing several key arms (including Pablo López and David Festa) who are expected to remain out for at least a couple more weeks. Bailey Ober is slated to return from the injured list on Wednesday, but even with his return, the team will need reinforcements to handle the upcoming innings load.
With Ohl joining the staff and Adams optioned back to Triple-A, the team has clearly shifted to a more fluid pitching plan in the short term. Even as the front office explores more changes ahead of the trade deadline, opportunities like this allow the Twins to evaluate their internal depth.
If Ohl can replicate his minor-league success, there’s a path for him to remain with the big-league club beyond just a spot start. Whether he becomes a multi-inning reliever or a more permanent fixture in the rotation, he will get his chance to prove he belongs. And if his 2025 numbers are any indication, he might just take full advantage of it.
