MELBOURNE, Australia (AP) — Defending champion Naomi Osaka has had a relatively trouble-free 6-3, 6-3 win over Camila Osorio in her first-round match on Rod Laver Arena. The four-time Grand Slam singles champion won the first five games of the match before Osorio hit back.
Osaka advances to the second round against either Dayana Yastremska or Madison Brengle.
Former No. 1 Osaka slid down the rankings last year after taking time out following her withdrawal at the French Open. She is 13th at the Australian Open, where she won last year and in 2019.
Osorio is ranked 50th in the world and was making her main draw debut at Melbourne Park. Next up on the same court is Rafael Nadal's match against American Marcos Giron.
