Matt Krook

Born: 10/21/1994 (Age: 21)
Bats: Left Throws: Left
Height: 6' 4" Weight: 225
Mechanics
Krook comes from a three-quarters arm slot. He showed an ability to repeat that arm slot, but occasionally finished the delivery short. There's some effort in the back half, but not enough to suggest he won't be a starter at the next level. There are some medical concerns here, as he underwent Tommy John in 2014.

Pitch Type Present Grade Future Grade Sitting Velocity Peak Velocity Report
Fastball 55 60 91-93 96 Potential to be an explosive fastball. Pitch had plenty of run, and when he stayed on top of the delivery he was able to command the pitch well to the arm-side. Struggled to locate anything to the glove side, which could be a case of nerves or there might be some adjustments needed, particularly in the back-half of the delivery.
Cutter/Slider 45 50 86-88 89 This is a new part of Krook's arsenal. Pitch had cutter velocity and slider tilt. He got underneath it often, and this was another pitch that he didn't throw for strikes on a consistent basis. Should be a competent third offering in time.
Curve 60 65 79-80 80 Krook only threw this pitch a handful of times, but hitters had no chance when he did throw it. Pitch had two-planes of break, big depth and hard spin. He located it for strikes, and he should be able to bury it when ahead with two strikes. Have to assume he didn't throw the pitch as often because they're limiting the amount of breaking balls as he builds up arm strenght.
Change 40 50 86-87 87 Threw a handful of changes. Some noticeable difference in arm speed, and while the pitch had some tumble to it -- almost split-like -- the deception wasn't there to call it an average pitch at this point in time.
Overall

This was Krook's first start at the collegiate level in 20 months, and there was definitely some rust to shake off, particularly with fastball command. Still, the amount of movement on his fastball was impressive, as was his big-league ready curveball. If this is the version we see all year he's more of a late first-round talent, but I would bet on seeing better command as we move forward, and more plus curveballs.
