Tomas Berdych took only an hour and 40 minutes to beat Dominic Thiem in straight sets and book his place in the US Open quarter-finals on Tuesday morning.
The world number seven easily bypassed his unseeded opponent with a 6-1 6-2 6-4 victory.
Thiem wasted three break-point chances in the opening game, and four in the fifth, but was on the back foot for most of the rest of the contest as Berdych broke him twice on his way to winning the first set.
The Austrian surrendered his serve twice more in the early stages of the second, as Berdych opened up a 4-1 lead which he rapidly converted into a two-set advantage on the Flushing Meadows show court.
Thiem is the youngest player in the world's top 50 and fought bravely, but there were no signs of him was getting on the Czech's serve in the opener in set three as Berdych stormed into the last eight.
He won two service games to love and two more to 15 either side of breaking Thiem, whose previous best performance at a Grand Slam was the second round, to set up a quarter-final with Marin Cilic.
