Australian Open: Alcaraz marches on; Kalinskaya ousts Stephens

Melbourne: Second seed Carlos Alcaraz led a group of players sealing berths in the Australian Open fourth round for the first time on Saturday as the second seed enjoyed a short outing that finished when his Chinese opponent Shang Junchen pulled up injured.

Alcaraz eased through two sets against Shang 6-1, 6-1 before his ailing 18-year-old opponent threw in the towel while trailing 1-0 in the third.

"This isn't the way anyone wants to move on," said the 20-year-old Spaniard, who takes on Miomir Kecmanovic next after the Serb beat 2023 semifinalist Tommy Paul 6-4, 3-6, 2-6, 7-6(7), 6-0.

"I want to wish him a speedy recovery. He's an amazing player. I was looking forward to this match. Unfortunately he wasn't in the best shape possible."

While Shang fell short in his bid to become the first Chinese man to reach the fourth round of a Grand Slam in the Open era, the country will have a women's singles player in the second week as 12th seed Zheng Qinwen beat Wang Yafan.

Zheng, who was named the WTA Tour's most improved player in the 2023 season after winning Asian Games gold and the Zhengzhou title, held off her plucky compatriot 6-4, 2-6, 7-6(8). The 21-year-old will no doubt be inspired by memories of Li Na's triumphant campaign in 2014.

"I watched that final 10 times," said Zheng. "Unbelievable player, the first Asian woman who won a Grand Slam, how can you not remember that?"

Zheng, who reached the quarterfinals of the US Open last year, next plays Oceane Dodin after she prevailed in an all-French third-round duel with Clara Burel 6-2, 6-4.

It was the end of the road for former Flushing Meadows champion Sloane Stephens after the American lost 6-7(8), 6-1, 6-4 to Anna Kalinskaya. By making it to the fourth round of a Grand Slam for the first time, Kalinskaya is already assured of her biggest payday - nearly $250,000 - though she seemed in no rush to spend it.

"I don't have anything in mind. I'll take it easy," said Kalinskaya, who faces Italian Jasmine Paolini next. "Maybe a nice purse."

French wildcard Arthur Cazaux sealed a breezy 6-3, 6-3, 6-1 win over Dutch 28th seed Tallon Griekspoor to reach the last 16 at a major for the first time where he will meet ninth seed Hubert Hurkacz of Poland.

Hurkacz downed Frenchman Ugo Humbert 3-6, 6-1, 7-6(4), 6-3. Dayana Yastremska will return to the fourth round of a Grand Slam for the first time since Wimbledon 2019 after her 6-2, 2-6, 6-1 win over American 27th seed Emma Navarro.

The Ukrainian next faces twice former champion Victoria Azarenka, who beat battled back from 4-1 down in the second set to beat 2017 French Open winner Jelena Ostapenko to go through 6-1, 7-5.
