Scouting Report

2026

Klein grew up in Brooklyn Park, Minnesota, just a quick drive away from Target Field. He spent two years pitching at Iowa Central Community College and signed with the Twins as an undrafted free agent in 2022 following a solid showing in the Northwoods League. He’s snuck up on people a bit, throwing in relative anonymity across two levels of A ball in 2023 and '24, but he took a big jump forward in '25, pitching his way from Double-A Wichita to back home with Triple-A St. Paul. He was rewarded with a spot on the 40-man roster in the offseason. He earned three Major League looks out of the bullpen in May 2026 and was traded to the Blue Jays at the Deadline as part of the return for Jeff Hoffman.

At 6-foot-5, 225 pounds, Klein looks the part but didn’t enter pro ball with the stuff to back up the optics. He was throwing around 90 mph out of the gate and now, thanks to added strength and work in the Twins’ velocity camp, sitting 93-96, topping out at 97.5 mph in Triple-A before the trade. Deception in his delivery helps the heater get some swings-and-misses. The addition of a curveball, and then adding some velocity to that, has turned it into his best secondary offering, an 80-mph breaker that is as close to an out pitch as he has, though he struggles to command it at times. He’s worked hard on an 85-86 mph splitter as well as an upper-80s cutter and also used a low-80s sweeper with St. Paul before heading to the Toronto system.

Considering Klein began with a below-average heater and no breaking stuff, this is a vast improvement. But the lack of a true put-away pitch could limit his ceiling. He was starting to work more out of the bullpen just before changing organizations in a sign of his future long-term role.

Pitch Movement

How this works: This section shows two different ways to evaluate pitch movement. On the left, “Total Movement” shows the real-world movement of a pitch, including the forces of gravity, which affects every pitch thrown. Since gravity requires time, and slower pitches aren't 'better' just because they have more time to move, a pitch's movement is compared to other pitches of the same pitch type, within +/- 2 MPH and +/- 0.5 feet of extension/release. On the right, Induced Movement (or IVB) is reported without gravity, and attempts to isolate movement created by the pitcher's ability to spin and manipulate the ball.
