Venus Williams will be back in the US Open at age 43, and Caroline Wozniacki will join her in the field for her return to grand slam tennis.
Both players were given wildcards into the tournament on Wednesday by the US Tennis Association.
Williams was the US Open champion in 2000 and 2001, two of her seven major singles titles. A year after younger sister Serena retired following the tournament, Venus Williams will be back in Flushing Meadows, where she reached the final in her debut in 1997.
She recently returned to competition after missing nearly six months because of injury and this week scored her first victory over a top-20 player in four years, beating 16th-ranked Veronika Kudermetova 6-4, 7-5 in the first round of the Western & Southern Open on Monday.
Wozniacki announced in June that she was returning to competition three years after retiring to start a family, and the USTA said then that she would be given a wildcard into the tournament where she was twice the runner-up. The former No 1-ranked player from Denmark, who has two children with husband and former NBA player David Lee, earned the first victory in her comeback last week in Montreal.
American women Ashlyn Krueger, Robin Montgomery, Kayla Day and Clervie Ngounoue also will receive wildcards into the main draw, as will Fiona Ferro of France and Storm Hunter of Australia, as part of reciprocal agreements with their tennis federations.
Ferro accused her former coach, Pierre Bouteyre, of sexual assault last year, shortly after losing in qualifying at the U.S. Open.
John Isner, a two-time US Open quarterfinalist who was long the highest-ranked American man, was given a wildcard for his 17th appearance in the main draw. Fellow Americans Alex Michelsen, Michael Mmoh, Steve Johnson, Ethan Quinn and Learner Tien also got wildcards, as did Benjamin Bonzi of France and Australian Rinky Hijikata.
Play in the main draw begins on 28 August.
