Yes, the brother has much better results.You mean he has much better results than his sister? I hope that is what you mean, because despite my bias, I recognize he has a lot of talent. If his sister is a lot better, than she would have to be like a pro.
You know what match confused me? I watched the beginning of the Girls' 12 finals (flipped between the two streams) and I couldn't get how the girl that lost (ret.) got all the way to the final with that style. She didn't seem to have a game, you know? She was slicing all of her balls, especially on her forehand side... It seemed sloppy and gimmicky. Am I missing something here? I mean, yeah, I'm sure that style keeps her opponents off balance, but I swear we have girls in my section that could probably beat her... Maybe she switched to this style to counter her opponent, who seemed pretty solid? Any info?
We go down to where that girl in the Herr finals trains a good bit. She is coached by her dad. I have seen her hit pretty hard, at least in practice. She is the top ranked national 12s for whatever that is worth. Maybe she was having some issues that caused her to retire and hit like you saw.
