Indoor season is coming and now we have already next figures:
1. John Isner 917
2. Milos Raonic 836
3. Nicolas Almagro 569
4. Sam Querrey 564
5. Roger Federer 559
It`s obvious that the leadership here will be decided between Milos and John. Isner made more aces till now, but he played 8 matches more. If we count toll of aces per match, Raonic is leader here.
So who takes it? I think Isner definately will take it if he qualifies to WTF. It`s unlikely though, then their chances look very similar to me.
And can you predict approximate quantaty? 1150 - more or less?
Also it can/will be the first time two players made 1000+ aces in one season. Krajicek and Ivanisevic
were close to do it 15 years ago, but Richard stopped at "only" 987.
