It was the latest in a series of early-for-her exits in recent weeks, including bowing out in the third round at the Paris Olympics, then going 1–2 at hard-court tune-up events before arriving in New York.
The 20-year-old from Florida did fight her way back into the match with a four-game run in which she claimed 14 of 17 points and grabbed the second set.
After each of her past two contests in New York, Gauff headed back out onto the practice courts to work on her serve. That didn’t help much on Sunday, when she tied her career high for double-faults. She also had 19 in a loss at the 2020 French Open. Against Navarro, Gauff delivered three double-faults in four different games. Eleven of the double-faults came in the final set alone.
Gauff attributed her problems to a mix of issues with her mechanics—“I go down on my left side a lot on my serve, and it’s something I’m aware of, but it’s tough in the moment to, I guess, try not to do it,” she explained—and in her mind.
“It’s sometimes more of an emotional, mental thing, because if I go out on the practice court right now, I would make, like, 30 serves in a row. I’ve done it before,” Gauff said. “I think it’s also just kind of a mental hurdle that I have to get over when it comes. ... But I definitely want to look at other things, because I don’t want to lose matches like this anymore.”
She finished with a total of 60 unforced errors—a whopping 29 on her forehand side.
“It was a little bit of a battle of will there for a bit. But proud of just my effort today,” said Navarro, a U.S. teammate of Gauff’s at the Paris Games. “I was able to stick in there through some tough moments.”
Frances Tiafoe eliminated No. 28 seed Alexei Popyrin, the player who stunned Djokovic, with a 6–4, 7–6 (3), 2–6, 6–3 victory on Sunday night. The No. 20 seed advanced to his third straight U.S. Open quarterfinal and will play No. 9 Grigor Dimitrov, who held off Andrey Rublev 6–3, 7–6 (3), 1–6, 3–6, 6–3 with 23-time Grand Slam champion Williams watching and offering a thumbs-up at match’s end.
Also moving on Sunday was No. 12 Taylor Fritz, who beat three-time Grand Slam finalist Casper Ruud 3–6, 6–4, 6–3, 6–2. Fritz’s quarterfinal opponent will be 2020 U.S. Open runner-up Alexander Zverev, who got past Brandon Nakashima 3–6, 6–1, 6–2, 6–2.
“I’m at the point now where I’m still happy to make quarterfinals, but I wouldn’t be happy with it ending here,” said Fritz, who has yet to reach a Grand Slam semifinal. “I definitely am at the point where I really want more than that.”
The quarterfinals will give Navarro another chance to play at Arthur Ashe Stadium in front of a big crowd. She'd never hit a ball in the place until Sunday—but felt rather at ease, anyway.
“I’ve been out on big courts before, where I just felt totally overwhelmed and almost like it’s an out-of-body experience. But I didn’t feel like that today,” Navarro said. “I felt comfortable from the time I stepped out onto the court, which I was a little bit surprised about. I kind of had prepared myself for the worst, just in terms of feeling overwhelmed and nervous.”
She sure didn’t perform that way.
Gauff was the one who was unable to bring her best.
“I expect better, but at the end of the day, it happened,” Gauff said, “and I know I can turn it around.”
