Jannik Sinner and Carlos Alcaraz survived US Open first round wobbles on Tuesday to stay on course for a semi-final showdown as two-time champion Naomi Osaka made a tearful and colourful return to Flushing Meadows.

World number one Sinner fought back from a set and break down to defeat 140th-ranked Mackenzie McDonald in his first match since being embroiled in a doping test controversy.

Alcaraz, the third seed and 2022 champion in New York, overcame a second set blip to defeat 186th-ranked qualifier Li Tu of Australia 6-2, 4-6, 6-3, 6-1.

Italian Sinner battled to a 2-6, 6-2, 6-1, 6-2 win over American opponent McDonald on Arthur Ashe Stadium, racing away with 18 of the last 22 games.

The 23-year-old was returning to action just a week after it was revealed he had failed two drug tests in March.

However, he escaped a lengthy ban when officials decided he wasn’t at fault for the presence of banned anabolic agent clostebol in his system.

“The response from fans, I feel it has been great, also throughout when the news came out, in the practice sessions, there was a lot of support,” said Sinner.

“It’s still a little bit not easy. You have to go through day by day.”
