  Scouting Report & Links      
         
  Physical Description: Average frame, filled out. No remaining projection.

Mechanics: Throws from a high three-quarters slot starting on the first base side of the rubber. Does not use a wind-up. Compact delivery with solid extension. Medium leg kick and short arm loop behind. Hides the ball. Works quickly. Effort in delivery.

Fastball: 91-93 mph. Tops out at 95 mph. Pitch shows average life and is used to generate weak contact rather than generate whiffs. Only throws around a third of the time. Average command-and-control profile. Potential fringe-average offering.

Slider: 82-84 mph. Short, 10-to-4 shape. Shape varies, with some having more depth than tilt while others more tilt than depth. Does not consistently snap off. Potential fringe-average offering.

Changeup: 84-86 mph. Shows fade and drop at its best. Throws with deceptive arm speed. Potential fringe-average offering.
  Curveball: 75-78 mph. Long, 12-to-6 shape. Show-me fourth pitch he will work in during longer outings on occassion, but uses sparingly. Designed mainly to steal a strike. Able to land for strikes and front door to right-handed hitters. Potential below-average offering.

Knuckleball: Anecdotally, added a knuckleball in the second half of 2024, but not yet scouted in games nor registered on Statcast in his Triple-A appearances.

Career Notes: Battled injuries in the summer of 2017, when he had surgery, and apparently in the spring of 2018. Pitched in a variety of roles in 2023 and 2024, moving between short relief, long relief, and the occasional spot start as needed.

Summation: Potential solid organizational depth arm. Lacks a carrying pitch, but fastball, slider and changeup are all fringy pitches and work well in combination to get out minor league hitters. Minimal ceiling, but throws strikes and is the type of depth arm every organization needs to fill out a minor league roster.
