You're absolutely right. Way worse control than in college. Only walked a little over 4 per 9 innings at T A&M. Maybe Miami was smart to pass on him and take Max Meyer. But I don't prefer short righthanders.
For me, I thought he would cut his walks and keep his dominate strikeout stuff when he pitched professionally full time. A reasonable assumption..
The guy is also 6'4" and over 200 lbs. He's a horse. Watch his video.
