'Quiet assassin' Rybakina targets world number one after Melbourne win
The Moscow-born Kazakh emerged from a power battle with top seed Aryna Sabalenka to claim the Melbourne title in three tight sets on Saturday.
The 26-year-old's 6-4, 4-6, 6-4 triumph brought her a second major crown, more than three years after winning Wimbledon.
Two-time Australia champion Sabalenka had her chances, notably leading the final set 3-0, but the fifth seed retained her trademark cool to pull through.
Rybakina later revealed that beneath her understated celebrations was huge relief.
