Stefanos Tsitsipas rallied from two sets down to defeat No. 2 seed Rafael Nadal 3-6, 2-6, 7-6 (4), 6-4, 7-5 in the Australian Open quarterfinals on Tuesday.
Tsitsipas, 22, became just the third player to come back from a two-set deficit against Nadal and the second in a Grand Slam (Fabio Fognini, 2015 US Open). The fifth-seeded Greek advances to face No. 4 Daniil Medvedev in the semifinals. No. 1 Novak Djokovic will face unseeded Aslan Karatsev in the other semifinal.
The 34-year-old Nadal, chasing his 21st Grand Slam title, was ousted in the Australian Open quarterfinals for the third time in four years. Tsitsipas is in a Grand Slam semifinal for the third time in his career.
