Elena Rybakina Becomes New World No. 1 at US Open

Elena Rybakina walked off Arthur Ashe Stadium on Wednesday night with more than a place in the US Open semifinals. She walked off as the new No. 1 in the world.

The numbers will become official on Monday, but the math is already done. With a 3-6, 6-1, 6-4 comeback win over Zheng Qinwen, the 27-year-old from Kazakhstan guaranteed she will replace Aryna Sabalenka at the top of the WTA rankings — no matter what happens the rest of the week in New York.

From slow start to statement win

For a set, Rybakina looked anything but the sport’s next standard-bearer. Zheng, the powerful French Open finalist from China, jumped on her, taking the ball early and ripping through the opener 6-3. Rybakina’s serve misfired, her timing was off, and the crowd sensed an upset brewing.

Then the switch flipped.

Rybakina tightened her first serve, started landing heavy blows of her own, and tore through the second set 6-1. The rallies lengthened, Zheng’s errors crept in, and the match shifted decisively. By the time the third set reached its business end, Rybakina looked every inch the player who has stalked Sabalenka’s ranking all season.

She sealed the 6-4 decider with the calm of someone who has been here before. Because she has.

A new No. 1, a first for Kazakhstan

With that final point, history followed. Rybakina becomes the first player from Kazakhstan — man or woman — to rise to world No. 1 in singles. She is the 30th player in WTA history to reach the summit, stepping into a small, fiercely exclusive club.

This was not a case of backing into the ranking. She needed at least a semifinal run in New York to overtake Sabalenka. She delivered it, and did so from a set down in a major quarterfinal.

Her ascent ends one of the great modern reigns. Sabalenka’s stay at No. 1 will close at 99 consecutive weeks, the sixth-longest streak in WTA history. In total, the Belarusian has spent 107 weeks at the top, having first climbed there on October 21, 2024. For nearly two years, every challenge ended with her still on the throne.

Rybakina has been the closest shadow in that time. Title for title, deep run for deep run, she has been the constant threat on Sabalenka’s shoulder.

Now she steps past her.

Gauff awaits, with New York behind her

The reward for Rybakina’s comeback is a semifinal against Coco Gauff, the former US Open champion and the face of American tennis. Gauff earned her place the hard way, surviving two match points in a wild 2-6, 7-6 (9/7), 6-2 win over 19-year-old French Open champion Mirra Andreeva.

“Elena is the new world number one,” Gauff said afterward. “It’s going to be a tough match. These are the moments you live for.”

New York will roar for Gauff. It always does. Rybakina will walk into a partisan arena as the newly crowned No. 1, chasing something even bigger: a third Grand Slam title to sit alongside Wimbledon 2022 and the Australian Open earlier this year.

Number one, but not done

The ranking, for Rybakina, is a milestone, not a destination.

“It’s just a number right now. My goal is to win the tournaments which I play,” she said. “It’s an amazing achievement, but you know how quickly everything can change in tennis ranking-wise.”

That perspective fits the current landscape. At the start of the US Open, three women stood within reach of No. 1: Rybakina, Gauff and Jessica Pegula. For Gauff or Pegula to leapfrog her, they needed to win the title and hope Rybakina fell before the semifinals. She didn’t blink. They ran out of room.

Pegula is still alive in the draw but out of the ranking race. Her path now runs through Sabalenka in the other semifinal — a heavyweight clash with its own storyline.

A rivalry on collision course

If Rybakina beats Gauff and Sabalenka takes down Pegula, the US Open will get the final it deserves: No. 1 versus the dethroned No. 1, a rematch of this year’s Australian Open championship match, which Rybakina won in three sets.

Sabalenka’s power. Rybakina’s precision. The woman who ruled for 99 straight weeks against the one who finally pushed her aside.

First, though, the new No. 1 has to silence a New York crowd desperate to see its home star back in a US Open final. If Rybakina can handle that noise and that pressure, the era she has just begun might feel less like a ranking change and more like the start of a new order.
