Newly crowned Australian Open champion Naomi Osaka was at Melbourne's Brighton Beach on Sunday morning holding the Daphne Akhurst Memorial Cup in her hands, hours after defeating Petra Kvitova in three sets in the tournament's final. Saturday's win also meant that Osaka became the new world no.1 in the women's tour. The 21-year-old Japanese was the first female tennis player to win two consecutive Grand Slam titles since Jennifer Capriati in 2001. Osaka won her maiden major title at the 2018 US Open.
