Scouting Report

Video scouting report »

Scouting grades: Fastball: 70 | Curveball: 55 | Slider: 55 | Changeup: 40 | Control: 35 | Overall: 40

Klassen is the 2023 version of Ben Joyce, who went in the third round to the Angels last July after hitting 105 mph with his fastball at Tennessee. He missed his first season at Minnesota in 2021 after having Tommy John surgery and worked just 7 2/3 innings last spring, allowing 14 runs and 14 walks. But he touched 100 mph in those brief looks, reached 102 while making progress in the summer Northwoods League and has continued to bring the heat this spring. 

Klassen may have the quickest arm in the entire Draft, producing a fastball that averages 98 mph with running action, and he has reached triple digits in most of his outings. His heater plays below its velocity, however, because it has ordinary shape and he has limited extension and control. He has an 82-86 mph curveball and a sharper 83-88 mph slider, and both can be plus breaking balls when he can command them. He almost never throws his changeup, an upper-80s offering with fade and sink that he can't land in the zone. 

While his arm speed helps him overcome a lack of physicality, Klassen has significant effort in his delivery and has yet to prove he can throw strikes. A well above-average athlete, he made significant strides improving his timing and keeping his mechanics in sync during the fall, when he pounded the zone, but his control has been well below-average again this spring. He still has a lot to prove, especially if he's going to be a starter, but his fastball definitely demands attention. 


2024

Scouting grades: Fastball: 70 | Curveball: 55 | Slider: 55 | Changeup: 40 | Control: 45 | Overall: 45 

After not pitching at Minnesota in 2021 following Tommy John surgery, Klassen was rarely on the mound upon his return in 2022. He showed off his stuff and a better feel for where it was going in the Northwoods League that summer. His arm strength as a starter back with the Golden Gophers landed him in the sixth round, where the Phillies were able to sign him for just under $300,000. He didn’t pitch after signing, but took a huge step forward -- especially in finding the strike zone -- during his first full season of pro ball and had earned a promotion from Single-A Clearwater to High-A Jersey Shore before being sent to the Angels in the Carlos Estévez deal close to the Trade Deadline.

Klassen has an extremely fast arm, and the right-hander has proven he can light up the radar gun consistently. His fastball sits in the upper 90s and touches triple digits, and while it didn’t have much shape or extension in college, his four-seamer featured more ride up in the zone during his pro debut; he also used a two-seamer effectively. He has thrown both an 82-86 mph curve and a sharper 83-88 mph slider, and both can miss bats when he lands them in the zone. There is an upper-80s changeup in his arsenal, but that arrow typically stays in his quiver. 

An outstanding athlete with almost a bouncy energy on the mound, Klassen’s biggest hurdle as he begins his pro career is his command and control. He walked 7.5 per nine innings at Minnesota a year ago, but he was making impressive strides in terms of staying in sync and on time with his delivery in 2024. There’s a lot of effort there, and the bullpen could still end up being his long-term home, but his gains while throwing more innings in a season than he’s ever amassed has put a huge up arrow next to his name.
