Stefanos Tsitsipas stormed into a third consecutive Australian Open semi-final with a straight-sets victory over Jiri Lehecka on Tuesday.
Tsitsipas has bowed out at the last-four stage in three of the past four years, but the Greek will get another chance to reach a first final after beating Lehecka 6-3 7-6 (7-2) 6-4.
The third seed from Greece fired down nine aces and hit 36 winners on Rod Laver Arena, winning without having his serve broken to set up a meeting with Russian Karen Khachanov.
Unseeded Czech Lehecka was broken in his first service game and Tsitsipas did not give him a look-in from then on in the first set.
The 21-year-old Lehecka had the favourite in trouble in the fourth game of the second set, but saw five break-point opportunities come and go.
Tsitsipas clinically won the tie-break to move a set away from the semi-finals, but Lehecka put up a great fight but was frustrated when he was unable to convert another three break points before the favourite held to lead 4-3.
Another tie-break looked possible until Lehecka's excellent run in only his second main-draw appearance came to an end when he netted a backhand following a thunderous cross-court winner from a fired-up Tsitsipas.
Tsitsipas maintains perfect quarter-final record
A first major title has so far eluded Tsitsipas, but he keeps knocking on the door and is two wins away from achieving that dream.
The 24-year-old is the fourth male player in the Open Era to be unbeaten in his first six grand slam quarter-finals after Rod Laver, Patrick Rafter, and Andre Agassi.
