Naomi Osaka claimed her maiden grand slam title in truly extraordinary circumstances at the US Open, as a furious Serena Williams became embroiled in a stunning row with umpire Carlos Ramos.
The ice-cool Naomi Osaka triumphed 6-2 6-4 at Flushing Meadows to become Japan's first grand slam singles champion, yet that immense achievement was overshadowed by sensational scenes of anger on the other side of the net.
Six-time US Open winner Williams, who remains one short of Margaret Court's record haul of 24 major singles titles, was initially disgusted after receiving a coaching violation from the umpire during the first set.
Williams was later handed a point penalty for smashing her racquet in set two and was then docked a game after continuing her protests at Ramos, seemingly calling the official a "thief".
To her immense credit, Osaka held her nerve among the chaos to claim victory, after Williams had remonstrated emotionally with the tournament referee, insisting she had been unfairly treated.
