Stefanos Tsitsipas has charged into his fourth Australian Open semifinal in five years as he chases an elusive breakthrough grand slam title, but it almost came crashing to a sudden stop after a moment of frustration in the third set.
Tsitsipas worked his way through the gears against Jiri Lehecka on Rod Laver Arena on Tuesday night to end the young Czech's fairytale run at the quarterfinal stage with an impressive 6-3, 7-6 (7-2), 6-4 victory.
