Sinner, Alcaraz move on after minor blips at US Open

NEW YORK : Top seed Jannik Sinner left the doping controversy that marred his U.S. Open preparations in the rear view mirror on Tuesday with a largely drama-free start to his campaign while fellow title contender Carlos Alcaraz also advanced after a minor blip.

Women's top seed Iga Swiatek overcame Kamilla Rakhimova 6-4 7-6(6) to reach the second round before two-times champion Naomi Osaka stunned 10th seed Jelena Ostapenko 6-3 6-2 on her return to New York after a maternity break.

The spotlight was firmly on Sinner in the day session as the Italian overcame a slow start to seal a 2-6 6-2 6-1 6-2 win over American Mackenzie McDonald a week after he was cleared of any wrongdoing over two failed tests in March for a banned drug.

Sinner, who has maintained his innocence, has been under intense scrutiny after escaping a doping ban but the 23-year-old was pleased to have the backing of fans on Arthur Ashe Stadium.

"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, which I'm very glad and happy about," Sinner said.

"It is still a little bit, you know, not easy. You have to go day by day ... I was curious to see how the reaction of the fans has been, but it has been very positive."

Alcaraz, another Flushing Meadows crowd favourite, gifted Australian qualifier Li Tu a set but the 2022 champion steadied the ship before closing out a 6-2 4-6 6-3 6-1 victory inside three hours.

LONGEST MATCH

Briton Dan Evans needed a much bigger effort to advance as he beat Russian 23rd seed Karen Khachanov 6-7(6) 7-6(2) 7-6(4) 4-6 6-4 in the longest U.S. Open match of the professional era -an exhausting five hours and 35 minutes.
