Novak Djokovic, Aryna Sabalenka and Emma Raducanu are in action on the opening day of the US Open.
Djokovic begins his quest for a 25th grand slam singles title at the scene of his last major triumph, when he defeated Daniil Medvedev to win his 24th two years ago.
The 38-year-old has not played since his Wimbledon semi-final defeat to Jannik Sinner last month, and opens with a tough test against young American Learner Tien, who stunned Medvedev at this year’s Australian Open and has hard-court wins over Alexander Zverev and Andrey Rublev this season.
Defending women’s champion Sabalenka has had a frustrating year at the grand slams but the World No 1 will be the heavy favourite against Rebeka Masarova in her opening match.
Raducanu has shown some good form on the hard courts as the 2021 champion returns to Flushing Meadows, where she will play a qualifier in her opening match.
