What actually happened today?
RV was doing something to his strings and Andy said the rule is that you have to wait until your opponent is ready otherwise you could just serve an ace because they're not. He said to Sky afterwards that the time violation should apply to receivers as well as servers and that umpire should watch both. I absolutely agree with him. It was a real injustice. Fortunately it didn't really affect things though Andy did seem to lose his rhythm a bit in the next game.
