  Scouting Report & Links      
         
  Physical Description: Filled-out right-hander with a mature frame. Sturdy lower half. No remaining projection.

Mechanics: Throws from a three-quarters arm slot. Starts on the first base side of the rubber. Medium leg kick. Stiff delivery. Arm hook behind. Rocks back at his peak and then drops and drives as he comes forward. Inconsistent timing with delivery leads him to pull off with his front side. Average athlete, good arm speed.

Fastball: 93-95 mph. Tops out at 98 mph. Heavy, generates a lot of weak contact on the ground. Throws strikes, but command is below-average. Really struggles locating to the glove side. Potential plus offering.

Changeup: 79-83 mph. Solid separation from fastball. Pitch shows late, parachuting movement. Throws with deceptive arm speed. Has shown bat-missing ability at the minor league level. Potential above-average offering.

Cutter: 87-89 mph. Hard, horizontal break. Primarily used to generate soft contact against right-handed hitters. Potential average offering.

Slider: 83-84 mph. Wasn't incorporated much in outings scouted in 2021.
  Career Notes: Signed as an undrafted free agent by Oakland for a $500 bonus out of Division II Newberry College in 2017. Was released the following April before signing just over a week later with the Angels. Made it to Double-A with that organization by early 2019 and pitched well. Tore the UCL in his pitching arm in early 2020 but avoided Tommy John surgery. Was released after the 2020 season was cancelled due to covid-19 and it became clear he would need some form of surgery. Underwent elbow surgery but was back throwing off a mound by November 2020 and signed with the Red Sox as a minor league free agent. Re-signed with the organization before reaching free agency after the 2021 season, receiving an invitation to Major League spring training. Participated in 2022 Winter Warm-Up.

Summation: Potential up-and-down major league depth reliever. Ceiling of a solid middle reliever. Lacks late-inning upside due to command profile, but could be a solid sixth-inning arm. Fastball and changeup both project to at least above-average offerings, with changeup showing true bat-missing ability. Cutter is more of a pitch-to-contact offering at present, but if it improves, would give him a third pitch that can miss bats.
