    View Draft Report
    A projection lefthander with a quick arm, Graves is listed at 6-foot-4, 195 pounds and has plenty of room to add strength and muscle mass in the future. He has mostly pitched in the upper 80s and touched low 90s numbers at peak, but it’s easy to see him increasing that velocity as he adds physicality in the future. He also throws a curveball in the upper 70s that will flash solid depth and has shown some feel for a changeup in the 78-80 mph range. Graves is committed to Clemson.
