Novak Djokovic has been eliminated from the Australian Open at the fourth-round stage after losing in straight sets to South Korea’s Chung Hyeon.
The six-time champion had been playing in his first competitive tournament since a six-month injury layoff and at times, the former world number one looked to be struggling with an ongoing issue with his elbow.
However, world number 58 Chung produced the performance of his career and held his nerve at the decisive moments in the match to run out a 7-6 7-5 7-6 winner.
Djokovic have battled back impressively to take the first set into a tie-break, but Chung was having success on his opponent’s first and second serve and it proved enough to take an early lead.
During the second, Djokovic looked to be on the verge of withdrawing from the match but after preventing Chung from moving a double-break ahead, the Serbian got back to 5-5, only to drop his serve once again.
The 21-year-old has now defeated Alexander Zverev – the world number four – and Djokovic in successive matches, and will now take on American Tennys Sandgren for a place in the last four in Melbourne
