  Scouting Report & Links      
         
  Physical Description: Ideal pitcher's frame. No remaining projection. Mature, filled-out frame.

Mechanics: Mid-to-low three-quarters arm slot. Drop and drive. Opens early with front side. Arm sweeps behind as it comes down and up. Steps toward right-handed hitter’s batter’s box and can get across his body. Quick arm. High-effort delivery.

Fastball: 93-95 mph when healthy. Hard cut in on right-handers with sink. Below-average command and control. Sat 88-91 mph in brief 2018 Spring Training look, which squared with reported 2017 velocity. Reportedly has hit as high as 100 mph and sat in the high 90s during college, but hasn't reached that velocity as a pro. Potential plus pitch at velocity shown since late-2018.

Slider: 83-86 mph when healthy. Has advanced feel for pitch. Shows tilt and bite. Can throw for strikes in the zone and get hitters to chase out of the zone at its best. Below-average control at present. Potential plus pitch with refined command and control. Sat just 77-78 mph in 2018 Spring Training.

Changeup: 84-85 mph. At its best will show drop and run. Velocity has increased from 78-80 mph in 2019. Clear third pitch. Below-average potential.
  Career Notes: Impressed scouts during a strong showing in the Cape Cod League in 2016, but biceps tendinitis limited him during his junior year at Seton Hall. Missed significant time in 2018 with back issues and a shoulder impingement, which may have led to significantly decreased velocity in spring training that year, but dominated during brief return late in the season. Initially skipped High-A to start 2019 in Double-A Portland after tremendous spring training, but struggled badly at the level and was demoted to Salem in May. Rebuilt his mechanics after demotion. Participated in the Fall Instructional League in 2018 and 2019.

Summation: Maddening inconsistency and injury issues make him difficult to project, with a wide range of outcomes. Possible that could continue into his major league career given the volatility of many relievers. At his best, flashes two plus pitches in a dominant-looking power fastball-slider combination, which would easily play in a major league bullpen, perhaps even in the back end. However, has never maintained that profile for very long, and his shaky, inconsistent control and inability to stay healthy raise significant questions about his ability to reach his ceiling, making it difficult to project him as more than an up-and-down reliever.
