10-11 - Kanepi's record against Top 10 players in Grand Slams prior to this week. The Estonian had won four of her last six Grand Slam matches against Top 10 opposition, dating back to the 2018 US Open, ahead of her clash with Sabalenka.

7 - Number of Top 10 wins by Petra Martic

, who added to that number by upsetting No.4 seed 6-7(5), 6-1, 6-2. The Croatian notched the first four of those between 2012 and 2019, and the most recent three in the past five months, having also defeated Anett Kontaveit in Rome and at Wimbledon this year.

22 - Number of times Alizé Cornet has reached the third round of a major, all within her record 63 straight main draw appearances. However, 2022 marks the first season in which the Frenchwoman has made that stage at each Grand Slam of the year.

3 - Players who have reached at least the third round of every Grand Slam in 2022. Along with Cornet (Australian Open quarterfinals, Roland Garros third round, Wimbledon fourth round), the others to have accomplished this are Iga Swiatek

(Australian Open semifinals, Roland Garros champion, Wimbledon third round) and (Australian Open and Roland Garros quarterfinals, Wimbledon third round).

6 - Times that Belinda Bencic

has reached at least the third round of the US Open in seven appearances. The Swiss player came from a set and 5-3 down to defeat for the first time in three attempts 3-6, 7-5, 6-2, reversing a 6-2, 6-7(3), 6-4 loss in the first round of Cincinnati two weeks ago. Bencic, whose best Flushing Meadows performance to date was her 2019 semifinal showing, owns a 76% winning percentage at the US Open, compared to 57% at the Australian Open, 54% at Roland Garros and 61% at Wimbledon.

6 - Grand Slam third-round appearances for Lauren Davis

, who rebounded from a bagel first set to defeat No.28 seed 0-6, 6-4, 7-6[5]. It is Davis' first time in the last 32 of the US Open on her 10th appearance at her home major. The American is 0-5 in Grand Slam third rounds to date; among active players, only (0-6) has reached more third rounds without a fourth-round showing.

6 - Months since Garbiñe Muguruza last won consecutive matches. Back in February, the Spaniard defeated Sorana Cirstea

and Madison Brengle to reach the Doha quarterfinals. She then won only four of her next 14 matches ahead of the US Open. However, she backed up her first-round win over this week with a 6-0, 6-4 defeat of another rising teenager, , to reach the third round at Flushing Meadows for a third time.
