Though, the match was controversial because  Serena Williams was penalized a game for calling the chair umpire a thief during an extended argument as the US Open women's final descended into chaos, with Williams' fans booing and play delayed before Naomi Osaka  wrapped up a 6-2, 6-4 victory for her first Grand Slam title.

In  defending her action, Serena accuses US Open umpire of sexism

Serena Williams says her assessment of a game penalty in the US Open final was due to umpire Carlos Ramos' sexism, as men have said "much worse" and not been penalized.

The biggest issue for Williams on the scoreboard Saturday was that she was outplayed by a younger version of herself in Osaka, a 20-year-old who is the first player from Japan to win a major singles tennis title and idolizes the 36-year-old American.

During the trophy ceremony in Arthur Ashe Stadium, thousands of fans jeered repeatedly, and both Osaka, the champion, and Williams, the runner-up in her bid for a record-tying 24th Grand Slam trophy, cried.

Williams put an arm around Osaka's shoulder and told the crowd: "I know you guys were here rooting, and I was rooting, too, but let's make this the best moment we can. ... We're going to get through this, and let's be positive. So congratulations, Naomi. No more booing."

Added Williams, with a laugh: "I really hope to continue to go and play here again. We'll see."

A teary Osaka addressed the pro-Williams crowd, saying, "I'm sorry. I know that everyone was cheering for her, and I'm sorry that it had to end like this. I just want to say thank you for watching the match. Thank you."

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

With Osaka halting Serena Williams goal of 24 Grand Slams, all eyes are now on the Japanese player to keep widened her scope in the tennis ranking.
