- Naomi Osaka won the US Open to become the first Grand Slam champion from Japan, beating Serena Williams 6-2, 6-4 after the American sparred with the umpire over violations.
- Williams was given three code violations, the first for coaching, which Williams vehemently denied, arguing, "I don’t cheat to win. I’d rather lose."
- She later demanded an apology, calling the umpire a “thief” and saying, "I have never cheated in my life. I have a daughter and I stand for what’s right for her."
