Winning a tournament without serving an ace
Wozniacki's 1st serve percentage has been quite impressive so far in IW; 186 of 250 = 74.4%!
But she hasn't served a single ace! If she wins Sunday's final also without serving an ace, would that be a first time in a Premier Mandatory?
And how often if ever has it happened at any level; Grand Slam, YEC, Tier I, Tier II & Tier III?
NB: Yes, I'm aware the Tier system isn't in use anymore.
