Minnesota Twins Prospect Retrospective: Connor Prielipp

Connor Prielipp has had much of his early pitching career marred by injury questions marks. Calling into question for most of his career whether he would be durable enough to make it to the majors. In a great turn of events, the left-hander has been on a path in which both his health and performance have made him the Twins' top pitching prospect and given him a much better chance to stick as a starter.

Struggle with Injuries
The native of Tomah, WI, in the heart of cranberry country, took his pitching talents to the University of Alabama out of high school. While his performance in college was phenomenal in his debut, it ended prematurely with the need to go under the knife and undergo Tommy John surgery. Even though the actual gameplay at the college level was limited, Prielipp showed enough potential with his stuff and talent level to be the pick for the Twins in the second round of the 2019 MLB draft. 

As Prielipp started his professional career, the injury issue continued to linger, with the need for an internal brace procedure in 2023. But in 2025, he was finally healthy, and all of baseball could see what his stuff and potential looked like over a full season of work. Spending most of the season at Wichita and ending the season in St. Paul, Prielipp logged 82 2/3 innings with a 4.03 ERA and 98 strikeouts (10.7 K/9). 

Healthy and Hitting His Stride
His 2025 performance was enough to create even more buzz around Prielipp; not only did the 25-year-old solidify himself as the Twins' top pitching prospect, but he also garnered a fair amount of national attention. Here at Twins Daily, he is ranked as the fifth prospect in the organization. ESPN had Prielipp ranked the highest amongst the national experts at 54th. Those accolades have only seemed to catapult Prielipp into this season, as he has been impressive in St. Paul. 

In 2026, Prielipp has appeared in four games for St. Paul and started three. Over 15 ⅔ innings, he has allowed four runs, striking out 22 and upping his strikeout per nine to 12.6 strikeouts. That performance was accentuated in his most recent start, in which Prielipp went five innings with eight strikeouts, one walk, and one earned run to collect his first win of the season. 

Prielipp’s 2025 success was largely predicated on his use of his slider, 4-seam fastball, and changeup. In 2026, each of those pitches is still an important part of his arsenal, but Prielipp has also employed an effective curveball to the mix, which has sat at an incredible spin rate of 3154 RPMs. Adding that to an already incredible slider-changeup combination has fueled the great numbers early from Prielipp. 

With health currently on his side, Prielipp is getting the chance to prove he can turn into a quality major league starter as he joins the Twins in New York. The Twins willingness to stick with the left-hander as a starter only echoes the confidence that the national prospect experts have shown in him. Almost every pitcher, as they enter the professional ranks, just wants a chance to prove they are a starter before being relegated to a bullpen role. 

At one point this offseason, it looked like Prielipp was going to have to be a backend bullpen arm. Due to a likely self-imposed innings limit to protect the prospect from injury, the Twins may turn him that way if he is effective in the majors. To start with, Prielipp will have a chance to prove that he has the durability to pair with the stuff to be a major league starter. A development that would be the best for both Prielipp the individual and the Twins as an organization.
