I know it is great to go through a tournament without double faulting like what Hingis apparently did at the US Open. However the mention of Hingis and her very weak second serve makes me wonder if that's really that important. I wonder what the percentage of second serve points she won against top players.
What would be a more interesting and more important stat would be the highest percentage of first and second serve points won. You can risk some doubles (like Sampras) if your second serve is strong overall.
Anyone here keep track of the highest percentage of service points won in a tournament? I know Krosero keeps track of consecutive serve points won.
