NEW YORK (AP) — The Latest on the U.S. Open tennis tournament (all times local):
U.S. Open champion Naomi Osaka tweeted she was "grateful" for her opportunity to play Serena Williams.
Osaka defeated Williams 6-2, 6-4 on Saturday night to become the first Grand Slam singles champion from Japan. Her win was overshadowed by Williams' getting hit with three code violations that led to a $17,000 fine.
"So there's been a lot going on but I just want to say, I was grateful to have the opportunity to play on that stage yesterday. Thank you," Osaka tweeted .

Ashleigh Barty and CoCo Vandeweghe have won the U.S. Open women's doubles final, beating Timea Babos and Kristina Mladenovic 3-6, 7-6, 7-6 at Arthur Ashe Stadium.
The 13th-seeded team of Barty and Vandeweghe knocked of the No. 3 and No. 1 seeded teams en route to their first Grand Slam doubles title as a team. They hadn't even dropped a set over that run until Babos and Mladenovic got them in the first set on Sunday.
The duo saved three championship points in the deciding set in a match that took more than 2½ hours to complete. Barty and Vandeweghe won the second set tiebreaker 7-2 and won the third 8-6 to win for the second time in four meetings this season against Babos and Mladenovic.
Vandeweghe, niece of former NBA star Kiki Vandeweghe, became the 17th American woman in the Open era to win the tournament title. The team had previously won the Miami Open in March. But winning at Ashe is as big as it gets. Barty and Vandeweghe kissed the trophy and won $700,000 for their championship.
Serena Williams was fined a total of $17,000 for three code violations during her loss to Naomi Osaka in the U.S. Open final.
On Sunday, a day after the match, the tournament referee's office docked Williams $10,000 for "verbal abuse" of chair umpire Carlos Ramos, $4,000 for being warned for coaching, and $3,000 for breaking her racket.
The money comes out of her prize money of $1.85 million as the runner-up to Osaka, whose 6-2, 6-4 victory on Saturday made her the first tennis player from Japan to win a Grand Slam singles title
Novak Djokovic will be seeking his 14th Grand Slam title and Juan Martin del Potro his second when they meet in the U.S. Open final.
Their showdown Sunday is del Potro's first appearance in a major championship match since he won the 2009 trophy at Flushing Meadows. He has had four wrist operations since then.
Djokovic missed last year's tournament with an injured right elbow that eventually required surgery, but he is back at the top of his game now and won Wimbledon in July.
He is playing in his record-tying eighth U.S. Open final and has won two in the past. If he beats del Potro, Djokovic will equal Pete Sampras for third place among men for major singles titles, trailing only Roger Federer's 20 and Rafael Nadal's 17.
