Build: Short, thin; needs to ad some strength in lower half but doesn't have a lot of room for growth in frame.
Mechancis: Low 3/4 arm slot; not smooth or fluid arm action, some violence in explosion towards plate, does not gather well at top of delivers, rushes thorugh; does not use lower half enough; arm action is stiff and short on back end; short stride leaves him throwing uphill over his front side.
Palm Beach Cardinals (High A, Cardinals)
50, Number 4/5 starter
Wide range of velocity on fastball, added and subtracted with pitch throughout game; some arm-side run, not enough to generate consistent ground balls; can flatten out easily due to lack of height and lower release point, no downward plane; average command, might not have much room for improvement due to effort in delivery.
Short, downward movement, did not show good depth; was able to change shape and throw slower with more break at times; used sparingly early in game and only against lefties, used against righties only third time through the order; commanded it well, threw for strikes consistently and kept low in zone.
A work in progress but has the potential to be an effective third pitch; throws for strikes consistently; can get too firm and overthrow; works best in high 70's to create velocity differential from fastball; shows more consistent arm-side movement than fastball; replicates his arm speed well; comfortable throwing it to same side hitters; will need some vertical movement to miss bats but has potential.
A lack of size and fluidity to his delivery leave Kaminsky without much projection despite being just 20 years old. He shows good pitchability for a player his age, understanding how to add and subtract with both his fastball and curveball and showing a feel for the development of his change-up, which has the potential to be a third above-average offering. None of the pitches showed as potential plus offerings, however, leaving him with a relatively high floor but a low ceiling as a back-end starter.
