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).

O nly 23 years old, World No. 1 men's tennis player Jannik Sinner will face No. 2 Alexander Zverev in Sunday's final. A win would give Sinner a similarly impressive five-major run

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.
