Defending champion Jannik Sinner will look to seal back-to-back Australian Open titles and deny second seed Alexander Zverev a maiden Grand Slam crown in the men's final on Sunday. Also on Sunday, the women's doubles final sees top seeds Katerina Siniakova and Taylor Townsend face Taiwan's Hsieh Su-Wei and Latvian Jelena Ostapenko.

In total, Sinner has won 36 of his last 37 matches, his only defeat coming against Carlos Alcaraz in the final of October’s China Open.

The 2025 Australian Open has been a bit wonky for U.S. viewers thanks to the time difference in The Land Down Under. The men's final match between Jannik Sinner and Alexander Zverev will begin at 3:30 a.m. ET tonight (or technically, early tomorrow, Jan. 26).
