Twenty-year-old Naomi Osaka won the US Open tennis tournament (Women’s Singles) on Saturday.
Osaka, who is Japanese-American, is the first Japanese person to win a major tennis tournament.
However, her win isn’t the only thing that made the tournament memorable. Something happened to her opponent, 36-year-old tennis star Serena Williams.
She was accused of being “coached,” which is not allowed during a match. Williams’s coach, who was sitting in the crowd, had made a motion with his hands to tell Williams how to hit a shot. However, Williams said she was not looking at the coach at the time and so did not cheat.
