NEW YORK — Serena Williams won her 347th Grand Slam match Sunday — two years on the dot since giving birth — and stood three matches from the summit of the U.S. Open, with 11 women in her way as she tries to navigate the six days to Saturday with one bandaged right ankle and one big hope to reach the gilded number 24.

While seeking to match the 24 Grand Slam singles titles of all-time leader Margaret Court, the Australian whose major titles came between 1960 and 1973, Williams still breathes in a field that has lost its Nos. 2, 3, 4, 6, 7, 9 and 10 players. A player with a compelling game, No. 2 seed Ashleigh Barty, departed Sunday. The player who beat Williams in the 2016 U.S. Open semifinals, No. 3 Karolina Pliskova, did likewise.

There remains No. 1 Naomi Osaka, the defending champion who romped through Williams here last year in a noisy final, but the rest of the field lacks for slews of Grand Slam moments. Osaka is the only other member of the final dozen to have won a Grand Slam — two, in fact — and other than that, none have reached a final. Only two have reached semifinals: No. 5 Elina Svitolina (who beat Madison Keys, 7-5, 6-4, on Sunday night) defeated Williams in the 2016 Rio de Janeiro Olympics and reached the Wimbledon semifinals in July; and No. 16 Johanna Konta, who Sunday chased away Pliskova, 6-7 (7-1), 6-3, 7-5, and has accessed three semifinals.

There are two other Americans having breakthroughs, 116th-ranked Taylor Townsend and 141st-ranked Kristie Ahn. There’s a hip pick to win the whole thing, Canadian Bianca Andreescu, with her seven wins over top-10 players this year, her significant title at Indian Wells and her bolt from No. 178 at the beginning of the year to No. 15 today. Townsend and Andreescu share Williams’s half of the draw.

But in further evidence of the flow of the women’s game, the 11 remaining have seen surprisingly little of No. 8 Williams across the net, even given her voluminous experience at 37.

“If you try to beat history and what Serena has achieved before on Arthur Ashe, she has no chance,” a French coach named Thomas Drouet said of his competitor. “The only solution is to beat the girl of now,” to try to offset “the Serena Williams of 2019.”

Drouet will burrow into pain­staking video study with that task from here to Tuesday. He coaches Qiang Wang, a 27-year-old from the metropolis of Tianjin in the northern part of China, not so far from Beijing. Some heady results in the past year, especially in Asia, have brought Wang to No. 18 in the world, and her 6-2, 6-4 win over Barty on Sunday brought her to Tuesday and to Ashe Stadium for sure and to Williams — the latter two for the first time.

“I don’t know,” the soft-spoken Wang said. “Let’s see.”

Williams played well in a fourth-round match of high quality with No. 22 Petra Martic of Croatia. It’s just that during Williams’s 6-3, 6-4 win, she rolled her right ankle while hitting a volley in the fifth game of the second set. That seemed ominous in a year in which she has suffered a left ankle injury that contributed to her quarterfinal loss to Pliskova in Australia, a virus that forced her to withdraw in Miami, a knee that forced her to withdraw in Rome and a back that forced her to withdraw mid-match in Toronto.

“I probably should have seen a trainer in Australia,” Williams said. “But I just thought [Sunday], I definitely thought about that, because ... the first thing was, like, ‘I’m finally healthy.’ The last thing I want is to have another bad ankle sprain. So I just wanted to get some compression on it [from a trainer, whom she called] and tape it even stronger, and that way I can at least try to finish the match.”

Her coach, Patrick Mouratoglou, said: “I was very happy with today’s match and also with the previous one, actually. I have no concerns at all.” He said Williams is “moving better now than she was a few months ago.”

“I feel like in this tournament, I guess, I have definitely turned a different zone,” Williams said. “I’m not sure if I can articulate what zone that is.”

She is 36-3 in service games this tournament. Martic said: “The variety of her serve is very amazing, I think. Sometimes she goes for those precise serves. They’re like two centimeters from the line, and sometimes she hits 200 kilometers an hour.”

Off she goes aiming for Saturday amid ample cheering from the New York crowds, whom she thanked profusely. “I don’t know if you guys know how much it means to me,” she said Sunday as they all hoped for something ­momentous coming Saturday.
