Naomi Osaka has won the Australian Open after seeing off Petra Kvitova 7-6 (7-2), 5-7, 6-4 - meaning she has now won back-to-back Grand Slams.

The Japanese sensation burst into the spotlight with her maiden Slam victory in America at the back end of 2018, defeating home favourite Serena Williams in the process.

Of course, that US Open final was sadly remembered for Williams' antics rather than Osaka's first title, but Down Under, it's all about the 21-year-old.

After taking a remarkable first set 7-6 (7-2), Osaka then somehow lost the second set despite having three championship points at one stage.

Osaka went 2-0 down in the second set, seeing her first service game get broken by Kvitova, only to fight back and win four games in a row, leaving her just two short of the title.

However, that's when the game went into overdrive.

Osaka had two chances at winning the match, but she failed to break Kvitova despite having three championship points, and then she failed to hold her own serve, leaving the score at 5-5 in the second.

After missing out on her chance, it seemed that the Japan star lost her focus, which led to her somehow losing the second set 7-5.

Despite throwing away the second set, the US Open champion regained her composure and won the third 6-4 to secure her second Slam.

As a result of winning the Australian Open, Osaka has now become the new women's number one, and will be looking to seal three in a row in a few month's time at the French Open.

For Kvitova, she will be disappointed not to be taking home the trophy, but deep down she will be so proud and happy just to be competing in finals once again.

Back in 2016 she was the subject of a burglary, which resulted in her getting into an altercation with said intruder.

The Czech sustained damage to ligaments and tendons in her playing left hand when fighting off the man, who was armed with a knife, which left her career hanging in the balance.

However, fast forward three years and she's back in Grand Slam finals, and that alone deserves massive respect.
