Rocker is an elite talent on the mound. He is very athletic and has great body control. He has an easy, repeatable delivery which means he does not need to overthrow to pick up velocity on his fastball.
The depth and run on Rocker’s fastball are impressive and he shows the ability to locate well. At times when he has failed to locate properly, he shows the ability to adjust his mechanics from pitch to pitch.
He has a solid three-pitch arsenal and just as many other pitchers his age, gaining consistency will be key in determining what type of pitcher he will be.
MLB Comparison: Michael Fulmer
Both pitchers feature a fastball, slider, changeup combination. They both go to their mid-90s fastball often and use a sharp slider as their secondary pitch.
