Kid looks good, really moves well and he seems to have good feel for the game. Is he serving some underhand? If he is, that's a no-no, IMO. It seems like he might be too focused on winning instead of hitting the proper serve. No one cares about Orange Ball wins, but his serve will be with him for the rest of his tennis career.
My daughter is around the same age and we did an Orange ball tourney a couple of weeks ago. Never again, complete mess.
For us to play Green Dot (or higher) USTA tourneys here in NorCal, they are forcing us to play Orange Ball for a season (or win 4 tourney's). You can't register unless you pass their lame test.
It was awful. It was all day, my daughter lost interest, it was boring and we didn't want to be there. Parents were, in general, ok, but you had a couple of weirdos. She won her round robin flight then we left, but this was after three hours. If she stayed, they winners of the other flights would have then played each other in another Round Robin, then after that, everyone was going to play doubles. It was going to be an (after travel) 8-9 hour day.
Way, way too much for an 8 year old.
The only benefit that it had was just playing with other kids, but since we are members of a pretty solid tennis club, we don't really need it.
I'm pretty sure that I am now going to wait until she is 10 so we can start playing normal tourneys, until then, she will be hitting with me and other members of our club.
