Defending champion Naomi Osaka has reached the second round of the Australian Open in style. The former world number one defeated Colombia’s Camila Osorio 6-3, 6-3 in Melbourne on Monday.
Osaka has slipped to 14th in the world tennis rankings. After the US Open last September, the four-time Grand Slam tournament winner had retired from tennis and taken an extended break. She had previously made her depression public. At the beginning of January, the 24-year-old Japanese returned to the tour after a four-month break.
