Coleman Wong's fairytale US Open campaign came to an end in the third round on Saturday. The man from the Hong Kong Special Administrative Region exited after a five-set thriller against Russia's 15th seed Andrey Rublev.

Wong bowed out in a 2-6, 6-4, 6-3, 4-6, 6-3 defeat on the USTA Billie Jean King National Tennis Center's Grandstand court. The experienced Rublev was pushed all the way by the 21-year-old, who trains at Rafael Nadal's tennis academy in Spain and had fought his way into the main draw via three qualifiers.

Wong is ranked 173rd in the world and delighted a packed crowd with some superb shots with his signature disguised drop shot repeatedly leaving Rublev scrambling at the net.

After his success in New York, Wong has now set his sights on breaking into the top 100. "I'm getting closer, and I've proved to myself that I can do it," Wong said of his rankings goal. "I need to keep believing. I can see that I have the potential and I can scare the big guys."

"I believe in myself more now. I was still in Challengers, and now I'm in US Open third round, almost beating a tough top 20 player, going five sets with them. It means I'm capable of pushing them all the way," added Wong.

Reigning champion Jannik Sinner also came through a testing encounter with Canadian 27th seed Denis Shapovalov to book his place in the last 16.

World number one Sinner rallied from a set down to beat Shapovalov 5-7, 6-4, 6-3, 6-3 and keep alive his bid to become the first man to retain the title in New York since Roger Federer in 2008.

On the women's side, Coco Gauff shrugged off her early round struggles to move into the last 16 with a straight-sets victory over Poland's Magdalena Frech.

Gauff, who had been reduced to tears during a labored win over Donna Vekic on Thursday, produced her most polished performance of the tournament to down 28th seed Frech 6-3, 6-1 in one hour 13 minutes.

The victory sends Gauff into a fourth round showdown against Naomi Osaka, who reached the fourth round of the US Open for the first time in five years with a three-set victory over Australian 15th seed Daria Kasatkina.

The 27-year-old four-time Grand Slam singles champion from Japan, who last reached the fourth round at Flushing Meadows during her run to the title in 2020, took advantage of Kasatkina's shaky serve to advance 6-0, 4-6, 6-3 on the Louis Armstrong Stadium court.

The win marks Osaka's best performance in a Grand Slam singles tournament since she returned to tennis last year following the birth of her daughter in 2023.

In the women's doubles, China's Xu Yifan and Yang Zhaoxuan survived a scare to reach the last 16, defeating Guo Hanyu and Alexandra Panova in three sets.

Xu and Yang needed just 34 minutes to win the first set 6-2, but Guo and Panova fought back to take the second in a tiebreak and level the match. The decider, however, belonged to the Chinese pairing, who imposed themselves 6-3 to seal victory. Up next for Xu and Yang are Timea Babos and Luisa Stefani on Monday.

China's Wang Yafan, partnering Japan's Shuko Aoyama, also progressed to the last 16. Taking full advantage of their serving, Wang and Aoyama wrapped up a straightforward 6-1, 6-3 win in 62 minutes and will meet the Russian duo Erika Andreeva and Diana Shnaider in the next round.

American veteran Venus Williams and 22-year-old Canadian Leylah Fernandez moved into the third round with a 7-6, 6-1 win over Norway's Ulrikke Eikeri and Japan's Eri Hozumi.
