Result
Rybakina goes to No. 1 whatever happens next: the semi-final berth ends Sabalenka's 99-week reign when the rankings publish on Monday, and makes her the first player from Kazakhstan, man or woman, to hold the top spot. She got there from a set down. The match's first break point did not arrive until the eighth game; Zheng took it, then served the set out through seven deuces, two double faults and five break points saved, Rybakina finishing the set 0-for-5 on break points. Zheng's first serve then fell to 35% and she hit one winner in the entire second set, against Rybakina's ten. Eight straight holds took it to 4-4, where Zheng earned her only break point of the third — and Rybakina, who had come to net five times all afternoon, came in anyway. The pass went long. Six points later Zheng double-faulted on the fourth break point of the game, and Rybakina served it out to 15. Zheng, a qualifier ranked 121st after elbow surgery, was the first woman to reach this round from qualifying since Raducanu in 2021. "It was definitely a battle inside me," Rybakina said.

At this Stage
The quarter-finals are the last eight, played across Tuesday and Wednesday. Everyone still here has won four matches on these courts, which is enough that seedings have stopped explaining anything and the form of the fortnight explains most of it. Four of the eight are gone within two days; the other four play for a place in the final.

What I said beforehand
The preview, frozen before the first serve. Clearly dated, never rewritten — that's the deal that makes the pick worth anything.
Zheng arrives having played nine hours and twenty-nine minutes of main-draw tennis, more than any woman left in the draw, and three qualifying matches before that; Rybakina arrives not having been on court for two hours in any of her four. That is the match in a line, and both readings of it are defensible. Zheng has come from 0-5 down in consecutive matches — the decider against Madison Keys, the first set against Iga Swiatek — and has said plainly that matches are what restore her rhythm, which is also the reason she gave for losing to Rybakina in Doha in February: for a long time, she said then, she had not competed. Rybakina has conceded 25 games in four rounds, the second fewest of the eight quarter-finalists, leads the tour in aces by roughly 140, and is 12-0 on hard courts this year against players ranked outside the top 50. The head-to-head reads 4-1 to Rybakina, the only player to have beaten Zheng on all three surfaces — and, more to the point, Zheng won the first set in both of their 2026 meetings and lost both. Madrid is the one to read: she out-aced Rybakina nine to seven and lost on 45 unforced errors, nine of them double faults, three of those in the game that gave away the second set. Tennis Abstract's hard-court Elo had Rybakina 2112 to Zheng 1808 before the tournament started, which works out at about 85-15, and that snapshot predates everything Zheng has done here. I shade it a long way down and still take Rybakina, because the way Zheng beats her is a long match, and nobody has had a long match with Rybakina for a fortnight.
The case for Elena Rybakina
72% to winRybakina has not dropped a set, has not played a match over two hours, and has spent barely more than five hours on court in four rounds against Zheng's nine and a half in the main draw alone. She serves better than anyone on tour — she leads the ace count by about 140 and finished the Osaka match with one — and a 66-minute match is precisely the shape that denies Zheng the rhythm she says she needs. She has beaten Zheng four times in five, on grass, on clay and on hard, and twice this year from a set down, so the pattern of Zheng starting well is already priced in and has already failed. What actually decided Madrid was Zheng's own error count, and Zheng has since played 45 more games than her opponent this fortnight. Rybakina won the Australian Open in January, beating Sabalenka in the final, is at a career-high No. 2, and reaching the semi-final here makes her world No. 1 outright whatever anyone else does. She has said she wants it.
The case for Qinwen Zheng
28% to winZheng is the only unseeded player left in the draw and she came through qualifying to get here, which no woman had turned into a US Open quarter-final since Emma Raducanu in 2021. Her fortnight is seven matches long and two of them were won from 0-5 down: seven straight games to take the third set off Madison Keys after saving a match point, then seven straight games to take the first off Iga Swiatek, whom no qualifier or lucky loser had ever beaten at a major — Swiatek was 15-0. The ranking beside her name is an artefact. She had arthroscopic surgery on her right elbow in July 2025, played two matches in the rest of that season and missed the Australian Open; before this week she was 11-13 for the year and had lost in the first round of qualifying in Toronto. That defeat produced a training block at IMG Academy with Pere Riba which she has called the hardest of her career, and her account of what it was for is the best line either player has given this fortnight: all the pieces were there, she told him, she just had not put them together. She has a major final, an Olympic gold medal and now three US Open quarter-finals — more than Li Na — and no points to defend.
Both cases written 2026-09-08, before the first ball — frozen into the record exactly as written, whatever the result. The percentages are mine — opinions with a percent sign on. They add to 100 because tennis has no draw to hide the rounding in.
My locked pick: Elena Rybakina to advance ✓ RIGHT
“Hard-court Elo says about 85-15 and the head-to-head is 4-1, with Zheng having taken the first set in both 2026 meetings and lost both. Shaded a long way down because Zheng's No. 121 is a post-surgery rolling-points artefact rather than her level and the Elo snapshot predates a fortnight in which she has beaten Keys and Swiatek from 0-5 down — but Zheng needs a long match, and Rybakina has not played one.”

Storylines
- Reaching the semi-final gives Rybakina the world No. 1 ranking outright, regardless of every other result. Losing on Wednesday does not end it: she still takes the ranking if none of Aryna Sabalenka, Coco Gauff or Jessica Pegula wins the title. Sabalenka, No. 1 since October 2024, must win the title and needs Rybakina to lose before the semi-finals to keep it.
- This is Rybakina's first US Open quarter-final at the eighth attempt — she had never been past the fourth round here — and it completes the set: she has now reached the last eight at all four majors.
- Zheng is the fourth women's qualifier of the Open era to reach the US Open quarter-finals and the first since Raducanu in 2021, and the first qualifier or lucky loser ever to beat Iga Swiatek at a major.
- It is Zheng's third US Open quarter-final, after 2023 and 2024 — more than any other Chinese player, passing Li Na's two — and her fifth at a major. She reached the 2024 Australian Open final, the first Chinese woman in a Grand Slam singles final since Li Na, and won Olympic singles gold in Paris the same year.
- Zheng had right-elbow arthroscopic surgery in July 2025, played twice more that season and missed the 2026 Australian Open. She was 11-13 for the year coming in, had lost in the first round of qualifying at the Canadian Open, and was ranked 121st; the Swiatek win alone moved her live ranking to 52.
- Rybakina retired from her Cincinnati quarter-final last month with a left ankle injury and said before this tournament that it had hurt to walk for days afterwards. She has since played four matches without losing a set.
- The winner meets Mirra Andreeva or the winner of Coco Gauff and Iva Jovic in the semi-final. That match was still being played when this was written.
Head to head
Five meetings, four to Rybakina, who is the only player to have beaten Zheng on grass, clay and hard: Wimbledon 2022, 7-6(4) 7-5; Beijing 2023, 6-1 6-2; Doha in February 2026, 4-6 6-2 7-5; and Madrid in April 2026, 4-6 6-4 6-3. Zheng's one win is the 2024 WTA Finals round robin in Riyadh, 7-6(4) 3-6 6-1. She took the first set in both 2026 meetings and lost both, each time over two hours and twenty minutes.
