  Scouting Report & Links      
         
  Physical Description: Athletic, sturdy frame. Filled out with minimal remaining projection.

Mechanics: Throws from a low three-quarters arm slot. Starts on the first base side of the rubber. Medium leg kick. Short arm action with some effort in the back. Low release height. Does a good job repeating his mechanics, but release point can get inconsistent. Hides the ball well.

Fastball: 92-94 mph. Tops out at 95. Velocity has returned at pretty much the same level as it was pre-Tommy John surgery. Above-average spin rate. Has shown the ability to pitch at the top of the strike zone and miss bats. Shows arm-side run and sink down in the zone. Has the fastball traits analytically-inclined teams look for. Fastball velocity reportedly constantly increased during college. Above-average potential.

Slider: 83-86 mph. Slurvey, 11-to-5 shape with two-plane movement. Sometimes struggles to land in the zone, but will flash depth and bat-missing ability. Fringe-average potential.

Changeup: 83-86 mph. Pitch shows late drop at its best. Solid feel. Will cut it at times also. Fringe-average potential.

Cutter: 87-89 mph. Short cut-slider. Consistent shape. Effective against lefties. First scouted in Spring Training 2025. Fringe-average potential.
  Curveball: 76-78 mph. Sweepy breaker. Seemed like a separate pitch that would sometimes run into his slider. Did not throw in outings scouted in 2024 after rehab from Tommy John surgery or in spring training 2025, but could be something he reincorporates more later as he starts to work deeper into games.

Career Notes: Did not receive any scholarship offers coming out of high school, so joined the club baseball team at Southern California. Tried out for the varsity team during his sophomore season and practiced with the team until being cut before the season. Worked with ex-major leaguer Joe Beimel and refined his mechanics, improving his velocity into the low 90s. Transferred to Northwestern for the 2020 season in order to continue pursuing a baseball career. Participated in the MLB Draft League following the conclusion of his 2021 college season. Participated in the Fall Performance Program in 2021. Underwent Tommy John surgery on June 14, 2023.

Summation: Potential organizational depth arm. Ceiling of an up-and-down, multi-inning reliever. Had limited pitching experience outside of pro ball, but possesses intriguing traits. Fastball has traits teams look for. Throws three secondary pitches, with his new cutter looking like a nice addition to his arsenal. Solid pitchability and feel on the mound. Stuff is on the fringy side, but if a secondary pitch takes a step forward in his first full year back from surgery, could see his stock rise. Excellent work ethic, ultra-competitive. Gets the most out of what he has.
