Duke Commit Cole Kuhn | 16 yrs old and just threw 101.7mph Offspeed pitches are coming together as well if that wasn’t enough Believe it or not, Velo hasn’t been the focus. Execution and Control has. Massive future ahead we are all looking forward to witnessing! @FlatgroundApp

How to get noticed on pro day 101: 1) If the schedule is running fast, stick to your provided time slot. Makem wait and anticipate 2) Pack a lip so big you have a hard time speaking to scouts 3) Sit an effortless 97-98 w 2-3 plus offspeeds 4) Go about your day

Athletic drills = efficient movement patterns. Efficiency = velo, command, and consistency. Be athletic @FlatgroundApp
