4 hours of match, it was necessary at least that.
The meeting between Tsitsipas and Sinner kept its promises.
It was finally the Greek who won in 5 sets (6-4, 6-4, 3-6, 4-6, 6-3) to reach the quarter-finals of the Australian Open.
Despite the Italian's fine comeback, Tsitsipas managed the fifth set perfectly, benefiting from several break points.
This is Tsitsipas' fifth victory in six encounters between the two men.
The world number 4 will face the surprise Lekecka (71st) in the next round, who defeated the Canadian Auger-Aliassime (7th) in the round of 16.
