MELBOURNE, Australia (AP) — Sebastian Korda reached the first Grand Slam quarterfinal of his career by beating 10th-seeded Hubert Hurkacz in a fifth-set tiebreaker at the Australian Open on Sunday.
Korda’s 3-6, 6-3, 6-2, 1-6, 7-6 (10-7) victory over Hurkacz followed up a third-round win against 2021 U.S. Open champion Daniil Medvedev, who had reached the final at Melbourne Park each of the past two years.
Korda is a 22-year-old American whose father, Petr, won the 1998 championship at the tournament. Korda’s mother was a professional tennis player, too, and his two older sisters play pro golf.
The 29th-seeded Korda will face 18th-seeded Karen Khachanov for a spot in the semifinals.
Khachanov eliminated Yoshihito Nishioka in straight sets earlier Sunday.
The men’s fourth-rounders also scheduled for Sunday: No. 3 Stefanos Tsitsipas vs. No. 15 Jannik Sinner, and No. 6 Felix Auger-Aliassime vs. unseeded Jiri Lehecka.
