  Scouting Report & Links      
         
  Physical Description: Thick, sturdy frame. No remaining projection.

Mechanics: Throws from a three-quarters arm slot. Long arm action. Max-effort delivery.

Fastball: 95-99 mph. Pitch shows life up in the zone and strong bat-missing ability. Potential plus-to-better offering.

Cutter: 88-91 mph, tops out at 94 mph. Short, horizontal break.

Slider: 82-85 mph. Sweepy shape. Has shown bat-missing ability with the pitch. Able to bury down and out of the zone and elicit chases.

Curveball: 81-83 mph. Two-plane break. Show-me pitch. 		  Career Notes: Was selected by the Mets in the 2023 Rule 5 Draft (in his second year of eligibility) and immediately traded to the Red Sox for Ryan Ammons and cash considerations. Reportedly had a lot of pre-draft buzz. Is subject to Rule 5 restrictions for the 2024 season. Participated in the Red Sox Rookie Development Program in January 2024.

Summation: Solid middle reliever with high-leverage potential. Fastball, slider and cutter give him three usable pitches. Has taken the necessary steps forward with his command and control to project as a major league bullpen piece. Has the stuff and demeanor you look for in a bullpen arm.
