Australian Open: Naomi Osaka defeats Petra Kvitova to be crowned champion and become world number one

Naomi Osaka beat Petra Kvitova 7-6 (2) 5-7 6-4 to be crowned Australian Open champion and become the new world number one.

The 21-year-old from Japan, the first Asian person to top the singles rankings, built on her maiden title at the US Open and made it back-to-back slam successes.


Naomi Osaka celebrates winning the Australian Open final.

Judging by what will surely be the first two of many slam finals, Osaka does not do routine. But, while her victory over Serena Williams in New York was all about controversy and meltdowns, this time the drama was all on the scoreboard.

At a set and 5-3 with Kvitova facing three match points, Osaka looked poised to stroll over the finish line only to lose four games in a row and the second set.

She had lost her head, too, but one of the most impressive things about her this fortnight has been the way she has overcome every mental hurdle placed in front of her and so it proved again.

Kvitova, who would also have become number one with victory, was playing in her first grand slam final since winning her second Wimbledon title in 2014 and only two years after the knife attack at her home that put her career in the balance.
