US Open 2018: Dominic Thiem reaches quarter-finals for first time
Ninth seed Dominic Thiem reached the US Open quarter-finals by beating 2017 runner-up Kevin Anderson 7-5 6-2 7-6 (7-2) at Flushing Meadows.
The Austrian broke late in the first set and twice in the second before winning the third in a tie-break.
It is the first time Thiem has reached the last eight in New York, and he will face the winner of the match between Rafael Nadal and Nikoloz Basilashvili.
South African Anderson was also runner-up at Wimbledon earlier this year.
French Open finalist Thiem called the win "one of his best matches ever".
Twelve months ago the 24-year-old had two match points in the fourth round against Juan Martin del Potro but lost in five sets.
"It's a dream coming true," said Thiem. "I was really close last year, but I couldn't close it out."
Roger Federer weathered an early storm to beat Australian Nick Kyrgios in three sets
