Austria's Dominic Thiem saved three match points rallied for a 3-6, 7-6 (9), 7-6 (4) win to oust No. 1 seed Hubert Hurkacz of Poland in the quarterfinals of the European Open on Friday in Antwerp, Belgium.
Thiem, who claimed the 2020 U.S. Open but hasn't won since then due in part to a wrist injury, absorbed Hurkacz's 17 aces and won 51 of his 63 first-service points (81 percent). He staved off Hurkacz when the Pole held a 6-4 lead in the second-set tiebreaker. Neither player broke serve in the third set before Thiem cruised in the tiebreaker.
Thiem will face Sebastian Korda in the semifinals after the 22-year-old American walloped Japan's eighth-seeded Yoshihito Nishioka 6-0, 6-2 in less than 53 minutes.
No. 2 seed Felix Auger-Aliassime of Canada had to storm back to defeat British fifth seed Daniel Evans 4-6, 7-6 (4), 6-2. He'll meet Frenchman Richard Gasquet in the semis; Gasquet beat Belgium's David Goffin 6-2, 7-6 (6).
