The U.S. Open Women's final ended in chaos after Serena Williams suffered a mesmerising meltdown on the court.
Instead, 20-year-old Naomi Osaka clinched the title, becoming Japan's first Grand Slam singles champion.
However her victory was overshadowed by a bizarre spat between Williams and an official.
The umpire Carlos Ramos sent Williams into a rage, after accusing her of receiving instructions from her coach, which isn't allowed.
