The Belarussian's 16th straight victory at Wuhan ended Gauff's own recent win streak at nine, including the China Open title last week. But it looked anything but certain for Sabalenka as she crashed 6-1 in the opening set. "In the first set she was just crushing it,” Sabalenka said. “Whatever she was doing, everything was flying in. Everything was so aggressive. I didn’t have much opportunities.” In a fight between the last two U.S. Open champions, Gauff led by a break early in the second but Sabalenka responded to pull level at 4-4 and saved a break point on serve to take a 5-4 lead. Serving to stay in the set, Gauff was broken as Sabalenka hit a lunging forehand volley to force a deciding set.

This is really difficult,” said Sabalenka, who had issues on her serve in the past. "But I know that if she’ll be able to overcome this serve situation, I’m pretty sure she’s going to be one of the greatest players.”
