MELBOURNE: Defending champion Naomi Osaka was knocked out of the Australian Open on Friday (Jan 24), falling 6-3, 6-4 in a stunning upset by American teenage sensation Coco Gauff in the third round.
Osaka was the third former Open winner to bow out of the draw after Serena Williams and Caroline Wozniacki, who won the title in 2017 and 2018, lost their respective matches at Melbourne Park earlier in the day.
