Naomi Osaka had just come back to secure her second United States Open singles title.

The crowd, unclear on the rules and upset at the treatment of Williams, booed during the awards ceremony, leaving Osaka in tears shortly after her first Grand Slam singles title.

Open title, Osaka was beaten in the fourth round by Belinda Bencic.

At the Australian Open in January, she played an error-filled match and was upset in the third round by Coco Gauff, then 15, an American whom Osaka had beaten in straightforward fashion at the 2019 U.S.

She initially declined to play her semifinal match in the Western & Southern Open the week before the U.S.

Tour officials responded by canceling the entire day of play and Osaka went on to reach the final, withdrawing with a left hamstring injury before facing Azarenka.

1 for 51 weeks in 2012 and 2013 and won two Australian Open singles titles before Williams reasserted herself at the top of the women’s game, and Azarenka dropped back.

She would have been the first mother to win a Grand Slam singles title since Kim Clijsters won the Australian Open in 2011.

As Azarenka dominated the opening set, hitting nearly every first serve in play and controlling the rallies, it appeared she might win in a hurry.

Her mood and game improved dramatically as the final progressed, while Azarenka failed to sustain her level of play.

After losing the second set and falling behind 1-4 in the third, Azarenka made one more surge, battling through a five-deuce game to hold serve and then breaking Osaka’s serve in the next game to close the gap to 3-4.

But at 30-30 on Azarenka’s serve in the next game, the match turned for good as Osaka won a high-velocity rally to get a break point and then converted it as Azarenka lined up a forehand, went for an inside-out winner and missed just wide.
