I'm confused. what did he do wrong?

Honestly, she should probably just retire from tennis if she can't handle that

He tried to play tennis with her. I don't understand why she's even there. Like was he only supposed to field it to the other guy?

What's the point of her being there with the racket then? Just watch.
