  Scouting Report & Links      
  Physical Description: Prototypical pitchers frame. Looks the part. Tall, filled-out with a sturdy but athletic frame.

Mechanics: Throws from a 3/4 arm slot. Controlled delivery with some effort. Starts on the extreme first base side and doesn’t use a wind up. Has a high leg kick and rocks back before coming forward. Slight stab behind, long arm action coming forward. Quick arm that can get out of sync with his delivery. Inconsistent release point. Delivery is more compact and repeatable from the stretch.

Fastball: 93-95 mph. Has 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. Potential plus-to-better offering.

Slider: 84-87 mph. 10-4 shape. Pitch will show depth and bite at its best. Really gets over the pitch at its best and 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 someoutings, but then relying on it later in the season. When at its best will flash plus and is his best secondary pitch.
  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.

76-80 mph. 11-5 shape. Average depth. Lacks bite. Viable pitch when sequenced correctly to steal a strike early in the count. Rarely thrown later in the count. Fringe-average potential.

Career Notes:
Was a Perfect Game All-American graduating from high school, where he pitched with Riley Pint and Joey Wentz. Added size and velocity in college.

Has the frame and fastball of a starting pitcher. Secondary pitches need work. If he can hone his breaking balls, changeup, and control could develop into a number three or four starter. Could move quickly in a bullpen role where he could cut down his arsenal and focus on his fastball and changeup.

State of the System: Low Minors Pitchers (4.2.20)
