It all began in the round-robin stage when she took out the world No. 2, Iga Swiatek, 6-3, 6-4. That flipped the script on Coco’s toughest head-to-head match-up on the tour—it was just her second win in 13 career meetings against the Pole.
Then, in the semifinals, Coco beat world No. 1 Aryna Sabalenka, 7-6 (4), 6-3. That’s been a more even head-to-head, but given Sabalenka’s form—she recently won huge hard-court titles in Cincinnati, the US Open and Wuhan—it was just as big of an upset.
When combined, Coco’s wins over Swiatek and Sabalenka that week made her the youngest woman to beat No. 1 and No. 2 at the same event since Maria Sharapova at the US Open… in 2006.
In Flushing Meadows that year, a 19-year-old Sharapova defeated then-No. 1 Amelie Mauresmo in the semifinals, 6-0, 4-6, 6-0, and then-No. 2 Justine Henin for the championship, 6-4, 6-4.
Coco was just two years old at the time.
