Felix Auger-Aliassim books Australian Open quarter-final berth
Canadian ninth seed Felix Auger-Aliassime earned a quarter-final berth when he outlasted veteran Croatian Marin Cilic 2-6 7-6(7) 6-2 7-6(4) at the Australian Open on Monday.
Cilic raced through the first set in only 35 minutes, but the long second set proved pivotal.
Auger-Aliassime squandered four set points under a baking afternoon sun, while also saving one with an ace.
But the 21-year-old finally won the set at the fifth opportunity to even the match, and dominated the next set as 33-year-old Cilic's errors mounted.
Cilic became frustrated at the length of time his opponent took between serves.
Both players held serve in the fourth set to set up a tiebreaker, in which Auger-Aliassime prevailed with outstanding serving, closing it out with an ace in front of a small but excited crowd.
