Rybakina closes in on WTA No.1: A quarter-final win over Zheng Qinwen would put her on top at US Open 2026

Late in the evening on Louis Armstrong Stadium, as Elena Rybakina closed out her match against Naomi Osaka 6-1, 6-4 with a service winner, the chair at her side of the court was still warm. She sat down, wiped the sweat from her forehead and looked up at the stands. On the big screen, her face appeared next to a small line: “One more win to become world number one.” New York had another late-night story — not about the two-time champion who had just been beaten, but about a Kazakh player standing on the threshold of history. Hours earlier, Zheng Qinwen had produced the tournament’s most stunning comeback, beating Iga Swiatek after trailing 0-5 in the first set. That victory sent Zheng into the quarter-finals and reshaped the draw for Rybakina. As the second seed, Rybakina was placed in the bottom half, where she was not expected to face a higher-ranked threat before meeting the reigning Olympic champion. Her path, however, was not as comfortable as the scoreline suggested. Osaka pushed back in the second set, forcing Rybakina to save break points with serves clocked at 190 km/h. After the match, Rybakina admitted: “If I serve as well as I did today, I think I can do well.” The quarter-final ticket now carries more weight than a usual place in the last four. With Aryna Sabalenka holding the No.1 ranking and defending 2,000 points from last year’s US Open, Rybakina only needs to beat Zheng to overtake her — regardless of Sabalenka’s result for the rest of the tournament. This comes from the WTA’s 52-week rolling points system: if Sabalenka fails to defend her title, the 430 points from Rybakina’s quarter-final run will fill the gap. From my experience following matches, a player being able to reach No.1 from the quarter-finals of a Grand Slam is a rare scenario. It reflects how consistent Rybakina has been in 2026: Australian Open finalist, Roland-Garros semi-finalist, and a regular presence in the late stages of WTA 1000 events. But Zheng Qinwen is not an opponent who will be intimidated by reputation. She won Olympic gold in Paris 2026, and her victory over Swiatek showed rare composure under pressure: down 0-5 in the first set, she still read Swiatek’s forehand trajectory and turned the match around. In terms of style, both players favour aggressive baselining, powerful serves and flat ball-striking. Rybakina holds the edge in reach and her first serve has become a destructive weapon on the medium-fast DecoTurf surface, where the ball skids low. This also allows her forehand to stay effective compared to clay. Zheng also possesses a strong serve, but she tends to hit with more spin, giving Rybakina the chance to step in and push her wide. The match will likely be decided by who can control points with their serve first. The 6-1 first set against Osaka was a clear indicator. Osaka, although past her 2026-2026 peak, remains one of the WTA’s best returners when she is timing the ball well. The fact that she won only four games in two sets suggests Rybakina maintained a high first-serve percentage and often finished points within four to five shots. However, I also see a potential weakness: Rybakina’s second serve is still a target for elite returners. Zheng returns deep and is willing to step in and attack whenever the second delivery lacks enough kick. If Rybakina’s first-serve percentage drops below 55%, Zheng has the ability to shift momentum. The most interesting dynamic is that the pressure of becoming No.1 may not sit with Zheng. Zheng has never held the top ranking, but she has been used to enormous expectations from the Chinese media since her Olympic gold — pressure is routine for her. Rybakina, by contrast, has shown signs of tightening in historic moments. In the 2026 Australian Open final, she led Sabalenka by a set before losing due to impatient shot selection. Her coaching team has also been unstable over the past two years, with several changes among assistants and sports psychologists. So this quarter-final is not simply a dialogue between two racquets; it is a dialogue between Rybakina and herself — between the desire to reach the summit and the fear of losing it all. I don’t just read the match; I read what players don’t say. Looking deeper, the tournament’s fault line may not be on the court but in the message the WTA is sending: the era of Sabalenka, Swiatek and Rybakina is being challenged by a generation that knows how to come from behind. Zheng has proven that. If she beats Rybakina, she will reach her second Grand Slam semi-final and make the race for No.1 far more chaotic. Even if she loses, her performance against Swiatek will be remembered as a milestone of growth. I have seen many young players break the order with power, but few have done it with the patience and self-belief Zheng showed in that match. The US Open 2026 is heading toward a beautiful paradox: a player can become world No.1 without winning the tournament, and an Olympic champion can decide who holds that position. Whatever happens in the quarter-final, Rybakina has shown the maturity of a true contender. But elite tennis never forgives carelessness: the No.1 chair is only a stop along the way, and the road ahead remains long. The only open question is whether she will have the courage to write history with her own serve, or let it slip away like a breeze through New York.
