Cameron Norrie, the British men’s number one, has been eliminated from the Australian Open after losing to rising star Jiri Lehecka.
Norrie, seeded 11th, had hoped to achieve another significant career milestone by reaching the last 16 at Melbourne Park for the first time.
He led by two sets to one before Czech Lehecka, 21, rallied to win the third round 6-7 (8-10) 6-3 3-6 6-1 6-4.
The 27-year-old left-hander was not at his best and required treatment on his left knee early in the game.
On Sunday, Lehecka will face Canadian sixth seed Felix Auger-Aliassime in the fourth round.
