Top-ranked Djokovic, who won the Australian Open, the French Open and Wimbledon to tie Federer and Rafael Nadal at 20 majors, will be seeking to become the third man to win all four Grand Slam singles titles in the same year. Don Budge in 1938 and Rod Laver in 1969 are the others.
Djokovic is also playing at the Tokyo Olympics and could become the first man to complete a “Golden Slam.” Steffi Graf did it in 1988.
World No. 3 Rafael Nadal, who skipped Wimbledon and the Olympics to rest, is also in the field and could be the biggest obstacle to Djokovic’s run at a Grand Slam.
The entry lists include players who make the field automatically. Players still can withdraw from the tournament.
Wimbledon champion and No. 1-ranked Ash Barty headlines the women’s field. Osaka, the defending U.S. Open champion, is ranked second ahead of Aryna Sabalenka, a Wimbledon semifinalist, and Sofia Kenin, the 2020 Australian Open champion.
This week’s ATP and WTA rankings were used to determine the entry lists. Seedings will be announced closer to the start of the tournament.
