Average build, narrow and evenly-proportioned frame. Lat injury (2014); T.J. surgery (September 2015); Ulnar nerve transposition surgery (May 2017).
Mechanical Notes
Upbeat, semi-windup delivery; tall leg kick w/ quiet gather over the rubber before starting drive. Lands hard/on his heel, leading to consistent off-line finish. Badly hooked arm circle; high-stress 3/4's slot.

Fastball Value
Overall Fastball Value 40 50 Projecting up on the velo and command as he builds back to form after missing two years w/ injuries. Won't ever overpower and will be hit hard when he misses.

Fastball Velocity 40 45 89 87-91 90-to-91 mph early in outings, thin/narrow frame contributes to lost velo quickly and settled into below-average 88-89 range. Will hold his velo better into games as he builds innings back.

ChangeUp
ChangeUp 45 45 84 83-86 Able to throw at arm speed; circle change w/ fade to arm side; has a feel for it, but not enough separation off his FB to miss bats. Serviceable third pitch.

Control
Control 40 50 On a pitch limit coming back from injury; has battled sequences of wildness in first few starts, but shows the signs of average control w/ flashes of 3-to-4 pitch mix around the plate.

Overall Summary
Strike-throwing lefty w/ fringy overall stuff; lacks carry tool to turn ML lineups over as a starter. Profiles in a swingman role, making spot starts while eating mop-up innings. High risk to profile given injury history and the injury flags are still present in mechanics.
