Iga Swiatek is only the 10th woman to record 90 or more weeks at No. 1 and is expected to remain there for at least the entire month of March.
This week, Swiatek begins a 93rd week atop the women's rankings and will soon eclipse Lindsay Davenport's tally of 98 weeks as World No. 1. The American sits in ninth place in the all-time list.
The Pole needs to make the Indian Wells quarterfinal to be absolutely sure of retaining her top spot, at least for the entire Sunshine Swing. But should Aryna Sabalenka falter in the early stages of Indian Wells, Swiatek might secure the top spot for the month before then.
Sabalenka is in second place with 8,725 points but drops runner-up points from Indian Wells. So, she'll most likely need to win the tournament to get closer to the World No. 1.
Coco Gauff stays in third place ahead of Elena Rybakina, who is on course to achieve a rare feat at Indian Wells in the next fortnight. Jessica Pegula recently returned to action at the San Diego Open after skipping the Middle East swing because of a neck injury.
The 30-year-old only reached the semifinal on her comeback, which didn't help in her bid to catch those above her. Ons Jabeur remains sixth but faces a significant battle to stay there, especially with her documented knee struggles.
Marketa Vondrousova, Qinwen Zheng, Maria Sakkari, and Jelena Ostapenko round up the Top 10. Emma Navarro rises to career-high ranking of World No. 23 after a run to the San Diego semifinal.
The eventual champion in San Diego was Katie Boulter, who surged 22 places to break the Top 30 for the first time (27th). Dayana Yastremska and Marta Kostyuk sit side by side in the 31st and 32nd of the new rankings.
Yue Yuan defeated Xiyu Wang in the all-Chinese final in Austin, Texas, to win a maiden WTA title. She is now China's new No. 3 player and soars to a career-high ranking of world number 49. Be sure to stay updated with all the ranking movements by visiting our dedicated rankings page.
