From Baseball America:
Dorchies is a 6-foot-6, 210-pound righthander with a low arm slot who’s committed to Illinois-Chicago. Dorchies pops in age based models due to being a young draft eligible high school player. He’s a projectible pitcher with plenty of room for further physical growth. Dorchies mixes two pitches with a four-seam 88-92 mph fastball and a 77-79 mph slider. Dorchies shows solid athleticism with excellent extension in his fastball. Although he has room to add velocity he also needs to improve his control.
