An injury-ravaged Novak Djokovic is out of the Australian Open, the six-time champion losing in straight sets to South Korean prodigy Hyeon Chung in the fourth round.
The 14th-seeded Serb needed a medical timeout for treatment of his injured elbow and was in obvious pain throughout as Chung stormed to a 7-6 (7-4) 7-5 7-6 (7-3) victory on Rod Laver Arena.
Chung will face world No.97 Tennys Sandgren in the quarter-finals on Wednesday after the aptly-named American’s shock defeat of Austrian fifth seed Dominic Thiem.
