Summer Breakout Prospects: College Pitchers


David Seifert
Director of College Scouting


Tyler Bremner, RHP, UC Santa Barbara- Bremner’s velocity has taken a substantial leap from high school as he now pitches comfortably in the 95-96 mph range. From a three-quarter release point his arm is super quick, his head quiet and overall it’s a starter ease of operation. He has three plus to better pitches in his fastball, breaking ball and changeup. His 79-82 mph changeup is the best of the three and grades as a 70 (plus-plus). He can land it for strikes on both sides of the plate vs right handed and left handed batters. It’s a nasty swing/miss pitch with depth and fade. He can also manipulate the action and cut it to his gloveside. Another near 70-grade pitch is his turbo sweeper at 88-89 mph. He also flashed a plus hook with more depth and up/down break at 84 mph. Bremner showed the best “stuff” of any pitcher I saw this summer and his changeup might be the best pitch in college baseball, comparable to Kevin Kopps’ (Arkansas) cutter in 2021. He’s also a low-pulse guy who looks to have an inner edge. Some scouts have already begun to compare Bremner to Aaron Nola. If the 2025 draft were next week, Bremner would likely be one of the first collegians off the board.


Jake Clemente, RHP, Florida- Clemente earned more trust as time went on last spring in his redshirt freshman season at Florida, and he carried that over to the summer, when he was Brewster’s most reliable starting pitcher. In 27 innings, he had a 3.00 ERA, held opponents to a .165 batting average and struck out 29, with his best game coming on July 17, when he gave up one hit to eventual CCBL champion Harwich in seven shutout innings. With a fastball that sits in the low 90s and occasionally touches the mid 90s, Clemente’s velocity on its own doesn’t necessarily stand out, but the amount of carry he gets on it does, and as a result, it appears much firmer than the radar gun suggests. He used the fastball a little over 70% of the time this summer, with his second-most-used pitch being a low-80s slider with two-plane break. It has potential as a wipeout pitch, but it’s still a work in progress. A mid-80s changeup is a distant third pitch for the righthander, who will return to Gainesville this fall with a chance to earn a spot in the weekend rotation. (Joe Healy- D1 Baseball)


Gabe Davis, RHP, Oklahoma State- Long and athletic at 6-foot-8, 225 pounds with a Jered Weaver-like-frame, Davis has front-of-the-rotation potential. He has the rare combination of a tall frame and a quick arm. He also repeats a compact delivery really well, especially for a human of his size. He controls a swing/miss fastball up to 99 mph (96-98 comfort zone) with a steep downhill path to the plate. He complements it with an 88 mph changeup and a swing/miss 86-88 slider, showing the ability to vary the shape with sweep or depth. Although firm, he showed good feel for his changeup, one that could turn into an above average offering. A tough competitor, Davis also has the intangibles with great makeup. While many in the scouting industry may get a future reliever vibe, Davis, for me, gets the nod as a future starter in pro baseball. Regardless, he’s a no doubt Day One prospect.


Chandler Dorsey, RHP, LSU (2025)- Dorsey made just three appearances in the Cape this summer, but he made them count by throwing 8.1 scoreless innings, giving up three hits and four walks with 13 strikeouts. The righthander, who is transferring from South Florida to LSU, is a physical presence at 6-foot-4 and 220 pounds. He has a heavy fastball that reached the mid-90s for the Harbor Hawks to go along with a putaway slider in the low-80s that had a 48% whiff rate this summer. Dorsey could be a fit for the Tigers at the back end of the bullpen, a role he held successfully for the Bulls last spring, or he could get a crack at the rotation, especially if he can further develop his changeup.

Michael Ebner, RHP, USC (2025)- It was a breakout summer for Ebner who became the ace of the Cotuit staff and one of the top performing pitchers on the Cape this summer. The 6-foot-3 right-hander allowed only eight hits in 23.2 innings and opponents hit just .105 while his WHIP was a ridiculous 0.59. He was the only pitcher on the Kettleers’ staff who began the season on opening day and finished the last day of their season. He also fired a scoreless inning with two strikeouts during the all-star game. With a compact delivery and some stiffness to his operation his best pitch is an above average cutter at 85 mph and his fastball sits in the low-90s. As additional offerings he also mixed a 79-82 mph breaking ball and a mid-80s changeup.


Anthony Eyanson, RHP, UC San Diego/LSU- Eyanson epitomizes what scouts are looking for in a pitcher with a loose and quick arm on a 6-foot-2 athletic frame. He fills the zone with a 95-97 mph fastball and a hammer-time 12/6 breaker in the upper-70s. It’s a plus-plus offering with consistent spin and control. He also repeatedly spots it up to his armside. He also showed a harder version, a power slurve at 83-84. There also looked to be more in the tank with his fastball and it’s a pitch that could very well bump into the triple-digits as early as this fall. Eyanson has first round potential and it should be a fun watch as to how it comes together in his new home of Baton Rouge.


Ben Jacobs, LHP, Arizona State- A personal favorite, Jacobs posted very good numbers as a sophomore starter for the Sun Devils in 2024. His 102 strikeouts in just 66.1 innings (35.2% strikeout rate) is a testament to his nasty stuff and his ability to mix his pitches. A 92-94 mph fastball is his main offering, but an above average split-grip changeup that he commands and an above average curveball are also legitimate weapons. He’s not afraid to double-up his change-of-pace and he’s also able to manipulate his 79-81 mph breaker for different shapes and looks. Overall, Jacobs is a high pitch ability left-hander with three average to better offerings and reminds of 2020 second-rounder Logan Allen (FIU/Cleveland) in many ways.


Braden Osbolt, RHP, Kennesaw State- A two-year stalwart in the Kennesaw State rotation, Osbolt was also a linchpin of the Y-D rotation in the Cape this summer, going 2-0, 2.28 with 15 strikeouts in 23.2 innings over five starts, en route to all-star honors. A strong-bodied 6-3, 215-pound righty with a fairly simple, repeatable three-quarters delivery, Osbolt is a sinker/slider specialist with feel for four pitches. His 89-92 mph sinker has solid life, helping him rack up a 56% groundball rate this summer, after inducing 53.7% ground balls with his heater this spring. He can feature a solid 84-86 mph cutter as his No. 2 pitch, but over the course of last spring he relied more upon his other two secondary pitches, a quality mid-80s changeup with good deception and sink, as well as a 77-81 mph slurve with three-quarters shape. Osbolt currently has a fastball that averaged 91.3 mph last spring, but if he can make a velocity jump, he could then climb draft boards. (Aaron Fitt- D1 Baseball)


JD Thompson, LHP, Vanderbilt- The 6-foot, 200-pound southpaw put together a strong sophomore season as a weekend starter for Vanderbilt (5-2, 4.15 ERA, 52 IP, 18 BB, 74 SO). He continued that success this summer for Bourne in the Cape posting a 1.93 ERA in 14 innings with 18 strikeouts, while issuing just four three passes. Thompson is a throwback ballplayer who is super-competitive and aggressive. He primarily pounds the zone with a 90-94 mph fastball that he can spot on either corner, but can also ride up in the zone for swing/miss. This past spring, his heater produced a 100th percentile whiff rate of 36.3% and he also spins two different breaking balls with an 80 mph slider being the most effective of the two. His low-80s changeup is the least advanced of the four. High round lefthanded pitching looks to be a strength of the 2025 college draft class and Thompson is a big reason why.


Joey Volchko, RHP, Stanford- An early candidate for 1-1 in 2026, Volchko has a loose, high-velo arm on a 6-foot-4, 210-pound athletic frame. His fastball touches 100 and will sit 95-98 for multiple innings. It’s a high spinner at 2500-2600 rpm with very good sink/tail life at times to his armside. He also shows a hard breaker at 90-93 that had more cutter shape and action, as well as an 85-89 slider that frequently flashes plus and induces multiple “sword” swings. At its best, it’s a tight spinner in the 2600-2800 rpm range with very good tilt. Volchko also flashed a plus low-90s changeup with good hand speed, and like his fastball, his change-of-pace showed good dive to his arm side. He can fall more into the “thrower” than pitcher mode at times in this stage of his development, but at times he did show an ability to pitch “backwards” with feel and finesse of his offspeed early in the count. Overall, Volchko presently controls his arsenal more than he commands it, but he’s easy to dream of as a future ace of a Major League rotation.


Kyson Witherspoon, RHP, Oklahoma- With great presence on the mound and a durable frame at 6-foot-2, 205 pounds, Witherspoon shows an easy delivery with compact arm action. He hides the ball well before unleashing a 96-98 fastball that he locates to all parts of the strike zone. His cutter is really tough to barrel at 91-92 mph and his above average to plus slider has big lateral action at 86-87 mph. His present changeup is too firm and a below average pitch at 90 mph, but all of his pitches are released from the same tunnel/same release point for the most part. Witherspoon is also a high aptitude learner and projects to the middle of a Major League rotation and day one next summer.


Blaine Wynk, RHP, Ohio State- Wynk thrived as a reliever at Ohio State last spring, but showed over the summer that there could be more in store in 2025. In 24.2 innings over seven appearances he had a 2.55 ERA and a .214 opponent batting average. An extremely fast worker with easy arm action, Wynk showed plus command of a fastball from 92-96 mph this summer to go along with a slider and changeup he can throw for strikes, and he also spent time working to add a curveball to the mix. With four pitches, a projectable 6-foot-3, 195-pound frame and stuff that could get outs at any level of college baseball, Wynk has a clear starting pitcher profile, even if that isn’t guaranteed to be his role in the immediate future.
