Naomi Osaka won the U.S. Open to become the first Grand Slam champion from Japan, beating Serena Williams 6-2, 6-4 after the American was penalized one game for a third code violation.
Williams was given three code violations by chair umpire Carlos Ramos, the third leading to an automatic loss of a game in the second set.
Serena Williams was given a second violation, this one for smashing her racket, and again yelled at the chair umpire who had given her a first warning for coaching.
The second code violation cost Williams a point, meaning Naomi Osaka had a 15-0 even before hitting her first serve in the sixth game of the second set.
