Naomi Osaka became the first Japanese player to win a Grand Slam on Saturday night when she defeated Serena Williams in the US Open final.
Osaka's win was overshadowed by a series of exchanges between Williams and the chair umpire during the game which saw the 36-year-old call Carlos Ramos a "liar" and a "thief".
It began in the second game of the second set when Ramos spotted Williams's coach, Patrick Mouratoglou, coaching his player via hand signals, an offence he later admitted.
Williams was assessed a points penalty when she smashed her racket on the ground later in the set and then a game penalty for verbally abusing the umpire.
By the time the presentation arrived boos were ringing out around Flushing Meadows. The moment drew tears from Osaka as the crowd showed support for Williams.
“I don’t want to be rude," said Williams as she called for the crowd to stop.
She played well. This is her first grand slam. Let’s make this the best moment we can.
Let’s give everyone credit where it’s due. Congratulations Naomi. No more booing.
Osaka told TSN after the presentation that she had been concerned for the player who had inspired her to take up the sport.
"It feels very emotional. I feel both happy and sad at the same time. This is the most I've ever cried.
"It was kind of difficult because I was really concerned about her and the inner fan in me jumped out. I really had to push to keep my straight face."
