Tempers Rise As Tetchy Medvedev Reaches Australian Open Quarter-Finals

Greek fourth seed Stefanos Tsitsipas won a titanic five-set duel with American Taylor Fritz to advance to the quarter-finals of the Australian Open on Monday. Tsitsipas was staring at defeat trailing two sets to one before he fought back to beat the 20th seed Fritz 4-6, 6-4, 4-6, 6-3, 6-4 in 3hr 23min of classic late-night tennis on Rod Laver Arena. The Greek world number four has now reached the quarter-finals for the third time and will face Italy's 11th seed Jannik Sinner, who accounted for Australia's Alex De Minaur in straight sets.

Tsitsipas is a two-time semi-finalist in Melbourne but is yet to win a Grand Slam title.

"It was an epic match. I gave everything out on the court today, I am very proud of myself with the way I fought and the way I stayed consistent in the moments that were close and crucial," Tsitsipas said.

"I am overwhelmed, it's too much, the stadium was on fire, it's too good to be true.
