Just as every other high school pitcher, there are some question marks about Stewart’s game. His mechanics can use some refining and at times he struggles to repeat his delivery.
Yet, with that being said – the sky is the limit for Stewart. He has one of the highest ceilings in the draft and can turn himself into a legitimate front of the rotation arm down the road.

Comparing anyone to Kluber is a definite reach, but if everything goes right in the development of Stewart, Kluber is the type of pitcher that he can become. He has the two plus-plus pitches to put his pure stuff in the range of Kluber, yet further development will have to happen.
Kluber is elite when it comes to pitch location and the way he is able to mix his pitches. Stewart will need to develop in order to turn into a true pitcher at the next level.
