Alex Eala and her fans are headed to the weekend at the U.S. Open, along with two-time champion Naomi Osaka and 2023 winner Coco Gauff. So is Madison Keys — just barely — but not No. 3 Felix Auger-Aliassime, who became the highest-seeded player knocked out of the tournament thus far. Osaka recovered after a mid-match lapse to advance to the third round with a 6-2, 5-7, 6-1 victory over Katerina Siniakova on Thursday, before Eala beat Oleksandra Oliynykova 6-1, 6-4. Doubles play also began, though Serena and Venus Williams won’t play their first-round match until Friday night against Hao-Ching Chan and Maya Joint, who beat Serena in singles play at Wimbledon this summer.
