Cooper Dossett was not only a well-known, high-profile high school prospect during his days playing at Har-Ber High School in Springdale, Arkansas, but he was a record-setting high school prospect; the right-hander set the Perfect Game national record by uncorking a throw from the outfield that was clocked at 100 MPH. A four-year letterman with the Wildcats, Dossett excelled on the mound as well as at the plate, with many scouts considering him one of the best overall players in the 2022 draft class from Arkansas and one of the best high school players nationally. Over the course of his Har-Ber career, he appeared in 79 games and hit .312/.432/.625 with 21 doubles, 2 triples, 10 home runs and 26 walks to 46 strikeouts while making 28 appearances on the mound and posting a 2.13 ERA in 98.2 innings, allowing 43 hits, walking 71, and striking out 188.
The two-way player had a strong commitment to the University of Arkansas and went undrafted in the 2022 MLB Draft, making his way to Fayetteville that fall. He appeared in two games out of the bullpen early in the season, but lost coach Van Horn’s confidence after allowing 4 runs in 1.2 innings and was not used again for the rest of the season during in-game situations. That’s summer, he pitched for the Green Bay Rockers of the Northwoods League to supplement his innings load, appearing in 13 games and posting a 4.83 ERA in 31.2 innings, allowing 29 hits, walking 18, and striking out 43.

In 2024, coach Van Horn gave Dossett a longer leash, but the right-hander failed to cash in on the opportunity, posting a 5.17 ERA in 15.2 innings over 14 relief appearances, allowing 7 hits, walking 7, and striking out 20. As if that were not bad enough, he injured his arm pitching in what ended up a 14-4 blowout loss against the Texas A&M Aggies on the final day of the regular season. He ended up tearing his UCL and requiring Tommy John surgery, which he got that fall. As a result of the recovery process, the right-hander missed the entire 2025 season. Draft eligible for the 2025 MLB Draft, Dossett did not hear his name called.
The right-hander returned to the mound this spring, his redshirt junior year. Appearing in 16 games, he posted a 6.88 ERA in 17.0 innings, allowing 12 hits, walking 12, and striking out 18. Following the end of the Razorbacks season, he played for the Williamsport Crosscutters of the MLB Draft League.
The right-hander throws from a three-quarters arm slot utilizing a full over-the-head wind-up, short-arming the ball. He threw from a low-three-quarters arm slot earlier in his Razorbacks career, and the mechanical changes seem to have been made in an attempt to improve his control and arm health. He utilizes a three-pitch mix consisting of a four-seam fastball, cutter, curveball, and the occasional changeup.
Dossett’s fastball sits in the low-to-mid-90s and has been clocked as high as 96 MPH this summer in the MLB Draft League. While that is barely passable velocity for a right-hander, and has an pedestrian four-seam fastball spin rate, Dossett is able to get a seam-shifted wake effect on the pitch so that it produces well above-average induced vertical break numbers, topping out as high as an elite 21.3 inches.

The right-hander’s cutter sits in the high-80s-to-low-90s, topping out at 91 MPH this summer with average horizontal glove-side boring action. His curveball sits in the low-80s and has power 1-7 break thanks to an above-average spin rate hovering close to 3,000 RPM. His changeup sits in the low-80s and is very firm, little more than a change-of-pace pitch to set up something else rather than a legitimate competitive offering.
