Four-time major champion Naomi Osaka and World No. 1 Aryna Sabalenka headline the women's competition, while World No. 1 Jannik Sinner, Alexander Zverev and Americans Taylor Fritz and Tommy Paul will compete as well.

Naomi Osaka ’s return to Grand Slam competition ended prematurely on Friday, as the two-time Australian Open champion was forced to retire from her third-round match against Belinda Bencic due to a strained abdominal muscle. Osaka had dropped the opening set in a tiebreaker, 7-6 (3), before informing the chair umpire she could no longer continue.

Top-ranked Jannik Sinner will face No. 2 Alexander Zverev and women’s No. 1 Aryna Sabalenka will play former No. 1 Naomi Osaka in exhibition matches March 1-2 in Las Vegas.
