Defending champion Naomi Osaka and Wimbledon 2021 winner Novak Djokovic were on Wednesday named to the US Open tennis field. The US Tennis Association (USTA) on Wednesday announced the lineups for the men's and women's singles. The Grand Slam will be played from August 30 to September 12 at New York's Flushing Meadows. The marquee tournament will see spectators return at 100% capacity after a year of curtailed audiences amid the COVID-19 pandemic.

Osaka and Roger Federer will both make a return to professional tennis after a break. Osaka had withdrawn from this year's French Open citing mental issues and also skipped Wimbledon. Federer will miss the Tokyo Olympics due to a knee injury.

Djokovic, having won 3 Grand Slams this year, is chasing a calendar-year Grand Slam. Only Rod Laver in 1962 and 1969 and Don Budge in 1938 have managed a men's calendar Slam. His Wimbledon victory lifted him level with Federer and Rafael Nadal with a men's record 20 career Grand Slam titles.

Djokovic, who will seek Olympic gold in Tokyo, could become only the second player to win all four Slam singles crowns and Olympic gold in the same year after Steffi Graf in 1988.

This year's US Open will witness the 103 top-ranked players on the ATP Tour battle it out for the trophy.

Other men's entrants include sixth-ranked defending champion Dominic Thiem, past US Open winners Stan Wawrinka and Marin Cilic, world number two Daniil Medvedev and fourth-ranked Stefanos Tsitsipas.

The women's draw will see Australia's Ashleigh Barty, the current World no. 1, feature along with 15 Grand Slam singles champions. Barty won the recently concluded Wimbledon. 

Four-time Grand Slam champion Osaka of Japan, ranked second, is also in the lineup along with 2020 Australian Open champion and world number four Sofia Kenin, fifth-ranked 2019 US Open winner Bianca Andreescu, eighth-ranked Iga Swiatek and former world number ones Garbine Muguruza and Simona Halep.
