Zheng Came Through Qualifying, Rybakina Came Through Untouched — Now One of Them Reaches the Semifinal

A US Open quarterfinal on Wednesday, September 9, and two players who arrived at the same door by completely different roads. Zheng Qinwen began this tournament in qualifying, played three extra matches to earn the right to stand where the seeds already stood, and has since twice climbed out of graves she dug herself. Elena Rybakina has not lost a set, has barely spent an unnecessary minute on court, and would finish the week as world No. 1 simply by winning one more match. There is no title to defend here for anyone, but the stakes are unusually specific: a ranking for one, a full-blown restoration for the other.

Zheng Found the Fire in the Least Glamorous Place on Site

Zheng's summer began badly enough that she used the word "disastrous" about her own qualifying in Toronto. After that loss, her coach Pere Riba told her plainly that competing without first rebuilding the game was pointless, so she skipped Cincinnati and disappeared into a training block at IMG Academy in Florida — tennis, physical work, recovery, almost nothing else. It reads like a small decision on paper. It looks now like the hinge of her season.

What came back first was not the technique but the temperament. Before New York, the pieces existed separately: serve here, forehand there, movement in patches, intensity in flashes. In qualifying she got the one thing a training block cannot manufacture — the rhythm of a scoreboard pressing on her. She admitted she became emotional after coming through, because all it bought her was a place on the same starting line as everybody else.

Then came Madison Keys. Zheng was overrun late in the first set, could not absorb the pace, could not build a point around her forehand. She turned the second set with heavier return pressure and then played the tie-break with real intent, taking it with winners rather than waiting for errors. In the decider she trailed 0-5 and faced match point at 1-5, held, sensed that Keys had stopped swinging — Keys later said as much, "I got really scared, like I couldn't swing" — and swept every remaining game.

Against Iga Świątek it happened again: 0-5 down, attention narrowed to the next ball to the point where she briefly lost track of the score, then seven games in a row and, crucially, a controlled finish rather than the usual emotional hangover. Świątek framed balls, lost her timing and said afterwards that Zheng gave her no room to switch into a safer mode. Zheng's own verdict was dry and accurate: "I guess coming back from 0-5 yesterday was not luck."

So the peak level is unmistakably back. The average level across a whole match is not there yet, and both comebacks needed an emergency to unlock it — plus, honestly, an opponent who tightened. Her right elbow, the one serious physical problem of the comeback, is described as a background recovery issue rather than a match-day concern; she practised again after beating Świątek. Riba's line for all of it: "Partido a partido, punto a punto."

Rybakina Walked In on a Bad Ankle and Has Barely Broken Stride

Rybakina's hard-court summer started loud and messy. In Toronto she struck the ball spectacularly and missed almost as often, double-faulted at bad moments and blamed jet lag, the toss, the legs, the conditions — a genuinely mixed bag, as the WTA put it. She still reached the final through hard, awkward wins over Naomi Osaka and Coco Gauff, before Świątek took the title match apart.

Then Cincinnati stopped her. She hurt her left ankle against Świątek, could not push off on serve, took treatment and retired. For a couple of days, she said, it was painful even to walk. A week off court, several doctors, mixed doubles abandoned, no proper final training block — that is the preparation she brought to New York.

The early rounds were deliberately economical. She was clean and unbothered against Thea Frodin after a long rain delay, and against Jessica Bouzas Maneiro she controlled both sets before failing to serve out the match — her only lost service game to that point — and answered it by attacking the return game instead of letting the wobble spread. Against Yuliia Starodubtseva she overhit forehands and lost serve late in the first set, broke straight back and let the delivery carry her through the tie-break. "It wasn't my best performance, but I was happy I got through," she said, which was the whole point.

The Osaka match was different. Rybakina served accurately, returned with real aggression, took the ball early and hit the first strike into the corners so that Osaka was always moving as she struck. It was, in the official phrase, absolutely relentless — not a scoreline handed to her, but one she built. "I played really well today. Feeling the ball was really good from my side," she said. This is also her first US Open quarterfinal, which completes her set of quarterfinals at all four majors.

No recurrence of the ankle has been reported, she calls her recovery amazing progress, and she is plainly the fresher player: shorter matches, no deciders, no doubles. She is calm in public about the No. 1 ranking, calling it a goal while insisting titles come first, and respectful about her opponent: "She definitely found her form… she's playing now with a lot of confidence, so she's very dangerous." Her stated priority is simply to keep serving as she served against Osaka.

The Question Is Whether Zheng Can Play Free Without First Falling Behind

The head-to-head is small but pointed. In Doha and again in Madrid this season, Zheng took the opening set and Rybakina turned the match around, absorbing the early level and gradually taking charge with the serve and the first strike. Both players walk in believing something true: Zheng knows she can win the early tactical battle, Rybakina knows losing a set to Zheng has never yet meant losing the match.

Tactically, the obvious pressure point is Zheng's second serve. Her first delivery is a weapon, but its consistency has flickered all fortnight, and Rybakina has been driving through returns rather than merely getting them back. If Rybakina keeps starting Zheng's service points from inside the baseline, Zheng may start chasing extra pace on both serves — never a healthy habit under mechanical strain.

Zheng's counter is shape and disruption. Rybakina is happiest against clean, flat pace arriving at a predictable height, so Zheng needs height on the forehand, heavy crosscourt balls that drag Rybakina off her central hitting base, changes of direction taken before Rybakina is balanced, and wide patterns that force her to stop and restart. Rybakina, for her part, will aim deep and early into Zheng's backhand corner to steal the space in which the Chinese forehand loads up — not to break the backhand down, but to stop Zheng organising points around her best shot.

Everything on a hard court here also points to the start. Rybakina has opened matches with authority; Zheng has needed time, and twice needed a five-game hole. Another slow beginning lets Rybakina play behind the scoreboard and shorten points at low risk; early return pressure from Zheng would test whether the ranking finish line makes Rybakina's serving arm any more careful.

The physical ledger is genuinely split. Zheng has the recent evidence of stamina, three qualifying matches and several long three-setters on her legs, and a coach who insists endurance is her greatest asset; the risk is a late drop in serve speed or forehand timing. Rybakina has the reserves but the less certain lower body — if the rallies stay short, the ankle may barely matter, and if Zheng makes her cover the width of the court repeatedly, it might.

The last factor is temperament, and it is where I have the most doubt. Keys froze and Świątek lost her timing; Rybakina's emotional flatness offers Zheng far fewer cues that a lead is slipping. Zheng has to find, while level or ahead, the freedom she has so far only found while drowning — and Rybakina has to keep swinging when a semifinal and the world No. 1 ranking come into view at the same moment. Neither of them should treat any lead as finished.
