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

Mechanics: Low arm action, submarine style pitcher. Slinging action. Inconsistent release point. Delivery can be a bit jerky. Average command and control.

Fastball: 89-91 mph, solid sinking movement and armside run. Tops out at 93 mph. Induces weak contact on the ground. Also mixes in an 88-90 mph sinker.

Slider: 77-78 mph. Above-average offering. Has tail and spin, induces swings and misses.

Changeup: 83-84 mph with some dive.
   Career Notes: Pitched out the the bullpen for four years at Gonzaga. Has had flashes of success as a closer at the lowe levels of the minors. Limited success in short major league stints with Seattle. Traded to Boston in December 2022. Missed the entire 2023 season, had Tommy John Surgery in July 2023. Non-tendered and signed a two-year minor league deal with the Red Sox in November 2023. Non-roster invitee to 2025 major league spring training.

Summation: Potential back of the bullpen contributor. Low ceiling as a major leaguer, but following injury could develop back into a pitcher that sticks on a roster for a few years.

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