MATCH REPORT: Osaka v Williams

Osaka took full advantage as Williams, her idol, battled with the officials over a number of violations that saw her docked a game and had the 23-time grand slam champion choking back the tears in the second set.

The 20-year-old's subsequent 6-2 6-4 victory proved unpopular as the crowd at Arthur Ashe Stadium, which jeered the beginning of the trophy presentation, was angered by the treatment towards Williams.

Having been comforted by the American great, Osaka apologised to the fans and thanked Williams in an emotional speech.

Asked how she found playing against her childhood hero, Osaka replied: "I'm going to differ from your question, I'm sorry.

"I know that everyone was cheering for [Williams] and I'm sorry it had to end like this. I want to say thank you for watching the match."

Turning to Williams, she added: "It was always my dream to play Serena in the US Open final. I'm really glad I was able to do that. I'm really grateful I was able to play with you. Thank you."
