Coco Gauff has become the first American teenager since Serena Williams more than two decades ago to reach the U.S. Open quarterfinals in consecutive years. She got that far this time by beating Caroline Wozniacki 6-3, 3-6, 6-1 on Sunday. Gauff asked one of her coaches to stop talking to her as the second set slipped away. She wound up winning the last six games. Gauff is 19. Wozniacki is a 33-year-old mother of two and was playing in just her third tournament since coming out of retirement last month.

Novak Djokovic has eliminated qualifier Borna Gojo 6-2, 7-5, 6-4 to reach the U.S. Open quarterfinals. Djokovic did not encounter any of the trouble that he did in his previous match. He needed to come back from a two-set deficit in the third round before eventually winning in five against Laslo Djere. Djokovic played far more cleanly Sunday night and was in control throughout. He finished with only 12 unforced errors, while Gojo made 40. Next up for Djokovic will be a matchup against No. 9 seed Taylor Fritz, a 25-year-old from California.
