Naomi Osaka became Japan’s first ever Grand Slam champion after she defeated Serena Williams 6-2 6-4 in a controversial US Open final on Saturday, with the American being handed a game penalty by the umpire.
With Osaka in control of the match, chair umpire Carlos Ramos handed the 23-time Grand Slam champion a game penalty for a string of code violations, including a coaching violation and verbal and racket abuse.
The game penalty put Osaka 5-3 up in second set and the 20-year-old Japanese kept her cool to pull off a historic win.
