Tools:Fastball: 70. Curveball: 60. Changeup: 45. Control: 30.

Clemmey has high-octane stuff and high risk that comes with it, a profile that has drawn big crowds to his starts this spring. Clemmey is 6-foot-6, 205 pounds and turns 18 shortly after the draft, so he’s one of the younger players in the 2023 class. His size, age and power arm from the left side are all appealing, with a fastball that sits at 92-96 mph and reaches 98 with riding life up in the zone. When it’s on, Clemmey has a curveball that flashes plus at 77-80 mph with sharp bite to miss bats, though some scouts felt that pitch hasn’t been quite as tight this year as it was last summer. It’s mostly a fastball/curveball attack for Clemmey, but he has shown feel for a changeup with good sink at times. The biggest questions for Clemmey stem from his control and delivery, and ultimately about whether he will throw enough strikes to start. He has an aggressive, high-effort delivery that’s difficult for him to repeat, with bouts of wildness and a track record of high walks. Clemmey’s mechanics and control troubles lead a lot of scouts to think his future is in the bullpen, a tough profile for a high school draft pick. If a team believes it can help Clemmey iron out his control, his pure stuff could make him an early-round pick.

BA Grade/Risk: 55/High

Adjusted Grade: 40

Track Record: The Guardians drafted Clemmey out of a Rhode Island high school in the second round in 2023, going nearly $1 million over slot to sign him for $2.3 million. Cleveland dealt him to the Nationals at the 2024 trade deadline as part of the package for Lane Thomas. Clemmey logged 116.2 innings in 2025 and led all Nationals minor league pitchers with 136 strikeouts but also 73 walks. He reached Double-A Harrisburg in mid August and saved his best work for last, when he posted a 2.04 ERA with 15 strikeouts and five walks in his final 17.2 innings.

Scouting Report: Clemmey’s exciting stuff gives him the potential to become a top overall lefthanded pitching prospect. It will come down to control, after he walked more than 14% of batters in 2025 to rank 11th worst among minor league pitchers with at least 100 innings. The 6-foot-6, long-limbed Clemmey has worked hard to streamline and repeat his mechanics, and his zone and strike rates on his fastball continue to creep upward. Opposing hitters have a hard time seeing his 93-94 mph four-seam fastball that reaches near 98. His arm slot and low release height make his heater difficult to square up for batters of both hands. He upped his sinker usage in 2025 to introduce a new wrinkle. Scouts would like to see him improve his fastball command to his glove side. Clemmey’s mid-80s slider has plus potential but wasn’t the same type of swing-and-miss weapon as it had been at Low-A in 2024. He threw many more changeups in 2025 to develop the high-80s pitch with above-average potential and good fade.

The Future: Clemmey exudes confidence and is a strong competitor with the athleticism to continue improving his command, which will determine his future role. He has the raw talent to become a No. 3 or 4 starter or potentially a high-leverage relief weapon.

Track Record: After winning Rhode Island Gatorade player of the year, Clemmey went to the Guardians in the second round—58th overall—of the 2023 draft. Cleveland swayed Clemmey from a Vanderbilt commitment by signing him to a well over-slot $2.3 million bonus. He made his pro debut in 2024 with Low-A Lynchburg, pitching to a 4.67 ERA in 19 starts and striking out 97 in 69.1 innings. At the trade deadline, Cleveland sent Clemmey to the Nationals as part of the package used to acquire outfielder Lane Thomas. He made six regular-season starts for the Nationals’ Low-A affiliate, ending his season with two postseason outings for the Carolina League champions.

Scouting Report: At 6-foot-6, 205 pounds, Clemmey has the type of projection that is easy to dream on. His fastball sits in the mid 90s with late life through the zone. He touched 98 mph in 2024 and could flirt with triple-digits as he adds strength. Clemmey’s windup is a bit untraditional, sometimes looking like it lacks rhythm. As he develops and adds strength, his movements should become more controlled and fluid. His curveball generates some swings and misses and has plus potential. The Nationals want to develop Clemmey’s changeup, which, as is often the case with high school draftees, is his least polished pitch.

The Future: Clemmey was one of the youngest players in the 2023 draft and shows his age with the rawness in his game. The tools are there, but expect Washington to move slowly with Clemmey. Though his development is a year behind Travis Sykora’s, the Nationals believe he could have the same type of breakout season once he matures and improves his control.

Track Record: Clemmey had a sensational high school career at Bishop Hendricken--the alma mater of Rocco Baldelli--and in 2023 was named Gatorade Rhode Island Player of the Year. The Guardians drafted him in the second round--58th overall--and Clemmey became the highest selected player from the Rhode Island prep ranks since 2004, when the Twins drafted righthander Jay Rainville at No. 39 overall. It was also the earliest the Guardians have drafted a high school pitcher since taking Daniel Espino 24th overall in 2019. Cleveland went well above slot to sign Clemmey for $2.3 million to buy him out of a Vanderbilt commitment. He did not pitch after signing.

Scouting Report: Listed at 6-foot-6, 205 pounds, Clemmey has a big, projectable build and high-octane stuff from the left side. His fastball gets up to 98 mph with riding life and typically sits in the mid 90s. Clemmey throws a sharp curveball that at its best is a plus offering and generates swings and misses. He mostly attacks hitters with his fastball and curveball, but he also can mix in a changeup with sinking action. Like most tall, hard-throwing teenagers, Clemmey is still working on his control. His delivery is aggressive and effortful, and he’ll need to learn how to more consistently repeat it to allow him to throw more strikes, because he has a history of higher walk rates. That gives him a high-risk, high-reward profile, but it’s easy to dream on his upside.

The Future: Clemmey will make his professional debut in 2024 with Low-A Lynchburg. He was one of the younger players in the draft class and won’t turn 19 until July, so the Guardians are likely to take a conservative approach with Clemmey, at least initially.
