For the first time in more than 20 years, the WTA Rankings had a historic shakeup. On Monday, Aryna Sabalenka officially captured the top singles spot, while US Open champion Coco Gauff and Jessica Pegula jointly rose to No.1 in the doubles rankings.

Sabalenka’s ascent ends Iga Swiatek’s 75-week reign at No.1, a position she held since April 4, 2022, the third-longest streak among players in their first stint as the top player behind only Stefanie Graf (186 consecutive weeks) and Martina Hingis (80).

More from the US Open

Sabalenka's season features three Grand Slam semifinal appearances, clinching her first major at the Australian Open and capturing additional titles in Adelaide 1 and Madrid.

In doubles, Gauff returns to the No.1 spot and is joined by partner Pegula. The American duo replaces Katerina Siniakova, who held the No.1 ranking for 52 consecutive weeks -- and 114 overall, the sixth most all-time.

This is only the eighth time in rankings history that the singles and doubles World No.1 ranking has changed hands on the same day.

Top 10 shakeup

On the heels of her US Open victory, her fourth title of the season, Gauff climbs a career-high ranking, moving to No.3 (from No.6). Gauff becomes the first player to hold the doubles World No.1 and a Top 3 singles ranking in the same week for the first time since July 26, 2010, when Venus Williams and Serena Williams held the co-No.1 spot in doubles with Venus ranked No.3 in singles and Serena No.1 in singles.

Marketa Vondrousova and Karolina Muchova join Sabalenka and Gauff among the current Top 10, with each reaching a career high. Following her quarterfinal run at the US Open, Vondrousova moves from No.9 to No.6, while Muchova rises from No.10 to No.8 after advancing to the semifinals in New York.

Comebacks gathering momentum

Several high-profile comebacks have taken place on the Hologic WTA Tour this summer, and a number of them gained pace at the US Open.

Former World No.1 Caroline Wozniacki reached the fourth round, defeating Petra Kvitova and stretching eventual champion Gauff to three sets, in just her third tournament back from maternity leave. The Dane soars up 380 places from No.623 to No.243.

Jennifer Brady, the 2021 Australian Open runner-up, played the fifth tournament of her comeback from plantar fasciitis in Flushing Meadows. The American won back-to-back matches for the first time since Roland Garros 2021 to reach the third round, falling to Wozniacki. She rises 170 places from No.433 to No.263.

WTA

The week before the US Open, Daria Saville's ranking took a hit as she lost her points from making the 2022 Granby final. The Australian former World No.20, who returned from an ACL injury in June, reached the second round of the US Open to bounce back up 56 places from No.322 to No.266.

Former World No.56 Patricia Maria Tig won her first Grand Slam match since Roland Garros 2020 to reach the US Open second round, and as a result shoots up 249 spots from No.700 to No.451.

Two-time major finalist Vera Zvonareva won three straight matches for the first time this year to qualify for the US Open, and rises 153 places from No.677 to No.524.
