  Scouting Report & Links      
         
  Physical Description: Medium frame. Good athlete. Some remaining projection, especially in his upper body.

Mechanics: Throws from a three-quarters arm slot starting on the first base side of the rubber. Cleaned up his delivery considerably throughout his time in college. Medium leg kick. Short strider with sub-5.7-foot extension. Jerky arm action with a short arm circle where he hides the ball behind his body. Average release height. Repeats delivery well.

Fastball: 95-97 mph. Tops out at 99 mph. Able to hold velocity deep into outings. Took a step forward with his command and control as a college junior. Pitch has average shape and flashed bat-missing ability more due to its velocity than its shape. Potential plus offering.

Cutter: 88-91 mph. Hard pitch with short, horizontal break. Used frequently and able to throw for strikes consistently. Shows bat-missing ability and is capable of generating chase. Potential above-average offering.

Slider: 84-87 mph. Two-plane shape. Flashes tilt and depth at its best. Able to land the pitch in the zone or bury it down and out when looking for whiffs. Potential average offering.

Curveball: 79-82 mph. 11-to-5 shape. Pitch has a high spin rate and considerable vertical depth. Struggles to consistently land it in the zone, but generates a bunch of whiffs when it is competitive. Potential above-average offering.

Changeup: 87-89 mph. Least-used offering in college, but already flashing potential as a pro. Throws with deceptive arm speed. Has late drop. Has the confidence in it to double it up against left-handed hitters. Potential average offering.
  Career Notes: Twin brother and college teammate, Malachi, was drafted by the Tigers in the second round (#62 overall) in 2025. Was not drafted out of high school (although his brother was). Both he and his brother pitched for Northwest Florida State Junior College as freshmen before transferring to Oklahoma. Pitched in the Cape Cod League for Chatham and for the Team USA collegiate national team after his sophomore year. Significantly raised his draft stock each year of college, particularly in his junior year, when developed into one of the top college arms while cutting his walk rate in half and adding velocity. Young for a college draftee, as he did not turn 21 until a month after the draft. Was a consensus top-10 talent in the 2025 draft and fell to the Red Sox at the 15th pick overall. Pitched in the 2026 Spring Breakout game.

Summation: Intriguing right-hander with big velocity and multiple potential above-average secondaries. Has mid-rotation upside if he continues on his current development trajectory. Made considerable strides with his command and control and continued to refine his secondaries as a college junior. Fastball plays more due to its velocity than its shape, and the latter could be something the Red Sox may tweak. Cutter and slider are distinct offerings, both of which he controls well and have strong bat-missing ability. Changeup and curveball both flash bat-missing ability, but he needs to find more consistency with each. Worked on a sweeper ahead of the 2026 season, as featured in a video that went viral on social media in which he appeared to pick up the pitch in less than 30 seconds, but he shelved it after it was impacting his fastball shape. Great makeup; hard worker who should fit well in the Red Sox pitching development program.

Note: This page will be updated with a complete scouting report after the scouting team has seen the player in regular season game action.
