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.

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).

Zverev got his spot in the Australian Open final — play is scheduled to start at 7:30 p.m. local time (3:30 a.m. EST) on Sunday — when 24-time major champion Novak Djokovic stopped playing because of a leg injury just one set into their semifinal on Friday.
