  Scouting Report & Links      
         
  Physical Description: Large, filled-out frame. Thick lower half.

Mechanics: True sidearm arm slot. Starts on the third base side, making arm slot hard on right-handed hitters. Medium leg kick. Gets good extension. Stays balanced throughout. Fringe arm speed.

Fastball: 90-93 mph four-seamer, tops out at 95 mph. Has some downward movement. Average offering. Also throws a 90-93 mph heavy sinker. Solid command and control profile.

Slider: 80-82 mph. Frisbee, sweeping breaking ball. Average offering. Relies heavily on the pitch.

Changeup: 85-88 mph. Late drop with armside fade. Show-me third offering.
  Career Notes: Attended Henry Ford College for two seasons before transferring to NW Ohio for two more. Low-bonus signing in 2016. Had a solid season in Worcester in 2021 in a swingman role, making some starts as an opener before making some true spot starts when club's pitching depth was thinned by injuries. Received a non-roster invitation to MLB spring training in 2022. Credited 2022 increase in velocity from 90-91 to 92-93 to working with Triple-A pitching coach Paul Abbott to clean up his mechanics and increased focus in the weight room.

Summation: Potential emergency major league bullpen depth. Fringy stuff, but arm angle and command could play. Has potential to catch lightning in a bottle for a few seasons at the MLB level due to the unique look he gives, especially against right-handed hitters.
