My 11 year old son is now laying the smack down to all his usta playing 6 days a week academy coached friends.... lol. He is coached by me. 2-3 days of tennis per week. 5'5" 145lbs. One day tennis per week during football season. His academy friends are shell shocked. I'm ecstatic. Since this past summer destroying the other kids and the adults at my club. He won't be a pro he is not that good but his game is coming along very well. It's classic to see grown men get destroyed by an 11 year old kid.... love tennis. just thought I'd share. Ha! I feel like brad!
