NEW YORK -- Second seed Dominic Thiem obliterated Canadian youngster Felix Auger-Aliassime in three sets on Monday to move into the quarter-finals of the US Open.
Thiem took just 2hr 7min to dismantle the 20-year-old 15th seed 7-6 (7/4), 6-1, 6-1 on Arthur Ashe court.
The Austrian won 74 percent of first serve points compared to just 60 percent for Auger-Aliassime.
The Canadian hit 51 unforced errors, with Thiem, the world number three, recording just 24.
Thiem will play Australia's 21st seed Alex de Minaur for a spot in the semi-finals.
De Minaur breezed past unseeded Canadian Vasek Pospisil 7-6 (8/6), 6-3, 6-2, in 2hr 17 min Monday.
The Slam was blown wide open after world number one Novak Djokovic was thrown out for accidentally hitting a line judge after smashing a ball in frustration during his last-16 match on Sunday.
His departure means the US Open will this year produce a first-time Grand Slam winner in the men's competition.
