How to watch: The match is at 3:30 a.m. Eastern time on Friday on ESPN, ESPN Deportes and ESPN+.
The Australian Open is the only Grand Slam event that splits its semifinals from the same singles draw, putting its second men’s singles semifinal alone on the Friday night session each year. It is the only time that a match other than a final gets such a showcase in the Grand Slam calendar, and this time the spotlight will be on two young stars: the fourth-seeded Daniil Medvedev, a 25-year-old Russian, and the fifth-seeded Stefanos Tsitsipas, a 22-year-old Greek.
