Serena Williams angrily responded to a code violation for coaching by telling the chair umpire that she'd "rather lose" than cheat.Williams was given the violation by Carlos Ramos, of Portugal, in the second game of the second set during the U.S. Open women's final while Naomi Osaka was serving.Williams approached the chair and told Ramos that she was not being coached but rather being given a thumbs-up from her box."I don't cheat to win. I'd rather lose," she told Ramos.Williams was given a second violation after smashing her racket, and she again yelled at the chair umpire who had given her a first warning for coaching.The second code violation cost Williams a point, meaning Osaka had a 15-0 score even before hitting her first serve in the sixth game of the second set.Williams resumed that argument after the second violation, still angry about the first violation. She unwrapped a new racket and then took the court to argue some more about coaching."You owe me an apology," she said. "I have never cheated in my life!"Williams was eventually given a third code violation by Ramos, which led to an automatic loss of a game in the second set.Serena Williams' coach said Ramos should have used better psychology instead of creating drama, because you "don't screw a Grand Slam final."Patrick Mouratoglou acknowledged coaching during the match, which is a rules violation. Mouratoglou says that "in 99 percent of the cases, (the chair umpire) would have told Serena, 'I've seen your coach do a movement and tell him to stop, otherwise you'll have a warning. And I don't understand why he didn't do that, where all the other chair umpires do this all year long, including him.'"
