slim, thin muscled frame; needs to add weight for durability purposes; fast momentum to the plate; live, whippy arm action; extremely fast arm; inconsistent landing spot and spin tilt at foot strike; hips open early but has arm speed to make up for it; short stride and lands on extreme stiff front side; has no lower half incorporation or leg drive; inconsistent mechanical profile.
Trenton Thunder (AA, Yankees)
50; 7th inning arm
late, explosive arm-side life; sinking action; shows good downhill plane; can get around and ball shows natural cut late in start; maintained velocity into 4th inning 95-97, had slight dip by 6th 92-94; improved command profile would allow pitch to play double-plus.
tight spin; short, tight breaker (exaggerated CT); late break with some tilt; plays well off of FB; commanded well to arm-side.
consistent arm speed; big sinking action; big deception in pitch; plays extremely well off of FB; can get too firm in upper velo band; has tendency to open up early and get extended, telegraphing the pitch.
Severino could very well be the best arm in the Yankees system. That being said, that doesn't make him a sure fire starting pitcher. I was not a fan of Severino's mechanics at all and I also don't think his build could withstand the longevity of a 200 IP season. He is a short strider and lands really stiff with a whippy arm action. His arm slot and landing spot both vary and everything got out of sync often. Severino stuff is very legit though. His FB is a live one and has explosive life while his CH is a big sinking pitch that plays well off of his FB. His SL is a short, tight breaker and he didn't use it as often as I thought he would. Severino's mechanical profile and build lead me to believe his future is in the bullpen, as an 8th inning man, where he can let it rip for an inning or two and he'll be quiet successful.
