Naomi Osaka claimed her first Grand Slam title on Saturday after defeating Serena Williams 6-2, 6-4, in the final of the U.S. Open. With the victory, Osaka became the first Japanese woman to win a Grand Slam singles title.
Williams was looking to win her 24th Grand Slam singles title, which would have tied her with Australia's Margaret Court for the all-time record. Williams lost after receiving multiple penalties from Chair Umpire Carlos Ramos — including a point penalty for breaking her racket, and then a game penalty for arguing with Ramos and calling him a "thief."
The game penalty came as a culmination of an on-going argument between Williams and Ramos. Earlier in the match, Ramos handed down a warning for coaching following hand gestures from Williams' coach Patrick Mouratoglou.
Williams responded by telling Ramos: "If he gives me a thumbs up, he's telling me to come on. We don't have any code and I know you don't know that, and I understand why you may have thought that was coaching, but I'm telling you it's not. I don't cheat to win. I'd rather lose."
