My 16 yr old son's windup came from Gunner.....he saw all the scouts at UTA to see Gunner last year (Gunners worst start all year😑 ) and has mirrored it since. He is a LHP & even wears similar leggings now too. Both similar height/weight. Its worked well for him.....up to 88-89 on fastball. Added 10 MPH since the change to Gunner 2.0
Maybe it's the socks cause it surely isn't his abilty....
