The seventh day of the US Open 2023 witnessed one of the biggest upsets, with World No.1 Iga Swiatek getting knocked out by Jelena Ostapenko in Round 4. With Swiatek’s defeat, her attempt to defend her New York title also came to an end. Meanwhile, American rising star Coco Gauff became the first player from her country to advance to back-to-back quarter-finals after the legendary Serena Williams. More history was created by Americans, with Ben Shelton, Frances Tiafoe and Taylor Fritz reaching the quarter-finals. It is for the first time that three American men have advanced to the quarter-finals since 2005, when James Blake, Andre Agassi and Robert Ginepri entered the quarter-finals at the US Open.
