  Scouting Report & Links      
         
  Scouting Report: Large, filled-out frame. Will need to watch his size.

Mechanics: High three-quarters arm slot. Clean mechanics.

Fastball: 93-94 mph. Touches 95 mph. Has reportedly touched 98 mph in the past. Velocity was down in the 91-93 range in July 2024 before he was shut down with elbow inflammation.

Cutter: 85-88 mph. Primary pitch.

Sweeper: 80-82 mph.
  Career Notes: Missed most of his sophomore season at Arkansas with elbow issues. Acquired in a trade for Luis Urias in November 2023, he looked very good in spring training and March/early April 2024, but after back-to-back blow-ups on April 10 and 11, went on the injured list with a right shoulder impingement, missing six weeks. Was optioned to Worcester after completing his rehab assignment, making only one more appearance in Boston before season ended in mid-July due to right elbow inflammation. Was designated for assignment and non-tendered in November 2024, but re-signed with the Red Sox on a minor league contract.

Summation: Profiles as a low- to middle-leverage MLB reliever.
