MELBOURNE, Australia — There will be a new-generation men’s semifinal at the Australian Open when Dominic Thiem faces Alexander Zverev for a chance to face Roger Federer or Novak Djokovic in the final.
Both defeated members of tennis’s old guard in the quarterfinals, with Thiem finishing off a thrilling victory over No. 1 Rafael Nadal after midnight on Thursday, 7-6 (3), 7-6 (4), 4-6, 7-6 (6). The match lasted more than four hours.
Zverev, the No. 7 seed from Germany, defeated Stan Wawrinka, a three-time Grand Slam singles champion, earlier on Wednesday, 1-6, 6-3, 6-4, 6-2.
