Defending champion Naomi Osaka confirmed her place in the second round of the Australian Open after a straight sets win over Camila Osorio 6-3, 6-3 on Monday.
Seeded 13 after taking a long break after a disrupted 2021 season, the Japanese showed signs of rustiness and none more obvious than the ninth game of the second set where her forehand return went towards the Chair Umpire.
