US Open 2018: Naomi Osaka Wins Title After Serena Williams’ Outburst

Naomi Osaka won the US Open after an angry Serena Williams accused the umpire of being a "thief" in some of the most dramatic scenes at a Grand Slam final.

Williams was given a game penalty for her outburst, which followed racquet smashing and another code violation as Osaka won 6-2 6-4 in New York.
