  Scouting Report & Links      
         
  Physical Description: Prototypical pitcher's frame. Looks the part. Tall, filled-out with a sturdy but athletic frame. Has some potential to add strength in his upper body.

Mechanics: Throws from a high three-quarters arm slot. Controlled delivery with some effort. Starts on the extreme first base side and does not use a wind-up. Has a high leg kick and rocks back before coming forward. Rough arm action with a stab behind and long coming forward. Quick arm that can get out of sync with his delivery. Inconsistent release point. Sometimes telegraphs breaking ball by shortening his arm swing. Delivery is more compact and repeatable from the stretch. Gets some deception from his front side.

Fastball: 93-95 mph. Hit 98 mph in three-inning stints with Lowell during his first season. Pitch shows sink when down. Above-average life. Likes to spot the pitch glove-side, but struggles to locate arm-side. Has the tendency to yank his fastball and will lose release point. Plus-plus velocity. Command lags well behind at present and projects as below-average at best right now. With improved command, could develop into a potential plus-to-better offering.

Slider: 84-87 mph. 10-to-4 shape. Pitch will show depth and bite at its best when he really gets over it. Will bury it down and out of the zone when ahead in the count. Had inconsistent feel during first season with Lowell, not utilizing the pitch in some outings, but then relying on it later in the season where it flashed significantly better. His best secondary pitch. Will flash plus at its best.
  Changeup: 83-86 mph. Throws with deceptive arm speed. Has splitter-like late drop. Has confidence in pitch. Uses primarily against left-handed hitters. Potential above-average offering.

Curveball: 76-80 mph. 11-to-5 shape. Average depth. Lacks bite. Viable pitch when sequenced correctly to steal a strike early in the count. Rarely thrown later in the count. Doesn’t consistently get over it. Fringe-average potential.

Career Notes: Added size and velocity in college. Developed a blister on his nail after signing, limiting his ability to throw his breaking balls in Lowell. Participated in 2020 Fall Instructional League. Began 2021 season in Low-A Salem but was sent down to the Ft. Myers complex in mid-July after significant struggles, working on the side on mechanics before re-entering games on August 31.

Summation: Has the frame and fastball of a starting pitcher. Secondary pitches and command need work. If he can hone his breaking balls, changeup, and control, could develop into a number four starter. However, could move quickly in a bullpen role, where he could narrow his arsenal and focus on his fastball and changeup, and fastball command would not be as important.
