A four-time Grand Slam champion, Osaka returned from maternity leave last year and lost in the first or second round of all four major tournaments. The 27-year-old Japan native has not won any event on the WTA Tour since capturing her second Australian Open title to start 2021.

Day six at the Australian Open was filled with shocking upsets and intense matches. Olga Danilovic of Serbia upset Jessica Pegula, while Novak Djokovic maintained his winning streak. Naomi Osaka retired due to injury.

Since returning to action a year ago, Osaka has shown signs of getting her game back together, including a memorable and narrow loss to then-No. 1 Iga Swiatek at the French Open.

Paul survived a comeback bid by Australia’s Chris O’Connell in front a feverishly partisan crowd; the American tightened up when he served for the match in the fourth set, then fought through a shoulder injury to take the decider 7-5. Nishikori, meanwhile, came back from two sets down, and saved two match points, against Thiago Monteiro.
