Re: Quito R2: Victor Estrella Burgos def.  Karlovic 6-7(7) 7-6(5) 7-6(8) (Saved 3
Had a look last night for Bo3 ace count on clay, last ten years Isner 31, Karlovic 30. Ironically, as with here, they both lost.
Pretty rare record because those 2 either don't play the events where it's likely to happen (Gstaad, Sao Paulo when it was indoors), or the competition is so strong they are likely to go out very early (Madrid).
