Andy had 8 aces to Novaks 2....
What does the number of aces have to do with it?
1st serve 60% AM 72% ND. Andy won 78% of 1st serves he got in which is good- he gets more 1st serves in he will win more points. He only won 47% of 2nd serve points though.
This has been something that's been said for seasons, he needs to improve his 2nd serve play but limit the openings there by having a higher 1st serve %
