Serena Williams lost the 2018 US Open final and her bid for WTA record-equaling 24th Grand Slam title to spectacular Naomi Osaka, but the 20-year-old’s impressive tennis and emphatic victory were somewhat overshadowed by her opponent’s tantrums and fight with chair umpire Carlos Ramos.
On the fifth point in the second game of the second set between Naomi Osaka and Serena Williams, the chair umpire witnessed coaching taking place from Williams’ coach. Even though her coach has admitted to coaching, Williams has made it clear that she did not receive any coaching.
