On Wednesday, Vekic was betrayed by her serve: she committed 14 double faults (against nine for Sabalenka), but above all she gave up her face-off five times when she herself only converted two of the 14 balls of break obtained in a match finally well controlled by his opponent.
Sabalenka, however, had a little trouble concluding: on two double faults she gave two break points to Vekic who got a third with a winning shot.
But each time Sabalenka came back and she concluded on her first match point.
