The title says it all, how good can Robert Stephenson be? He's currently dominating Midwest League hitters at age 20 to the tune of a 3.32 ERA, 2.40 FIP, 2.41 BB/9, and a very impressive 11.61 K/9, while only allowing 4 HR in 59.2 innings. His fastball is explosive in the mid to upper 90's and his breaking ball is considering a plus pitch, with a chance to have a plus changeup down the road.
I've seen some people say he has the best arm to come through the Reds organization since Don Gullett. So I have question for those who have seen him pitch, is he a potential legit ace? Is there a pitcher he reminds you of? It's hard not to be excited about him right now. Hopefully he stays healthy.
