MELBOURNE, Jan ‌20 (Reuters) - Twice Australian Open champion Naomi Osaka floated onto ‌Rod Laver Arena in a jellyfish-inspired outfit and claimed a ‌see-sawing 6-3 3-6 6-4 win over Croatian battler Antonia Ruzic to reach the second round at Melbourne Park on Tuesday.

Turning centre court into a catwalk, the ‍former world number one raised gasps ‍in the crowd as she ‌entered in a riot of colour, toting a white parasol, a ‍matching ​broad-brimmed hat and wearing a marine-themed top complete with pastel yellow tassels on the sleeves.
