I know that you are being sarcastic about Butch to degree- but Mitchell in high school was under the radar because he got hit in the face with a baseball while playing SS. In high school, he was topping out at 89. Now he is topping out at 95. Butch has to get some credit for that. I also have to credit Butch for finding him. But what really has impressed me is his control. He just pounds the strike zone.
To me, he doesn't look like he has filled out either. He should get stronger, and he will need to add another pitch as he continues- very similar to Chris Stratton last year, except that we don't have to ask Evan to be our ace and go nine every time out.
If he stays healthy- or as you say, if Butch doesn't F up his arm, he could be a fairly high draft pick by the time he is a junior.
