Defending champion Novak Djokovic crashed out of the Australian Open after falling victim to a stunning five-set defeat at the hands of wild card Denis Istomin.
Djokovic was chasing a record seventh title in Melbourne, but his pursuit is over for another year after Istomin, ranked 117th in the world, edged a mammoth contest 7-6 (10/8) 5-7 2-6 7-6 (7/5) 6-4.
It was only his second loss to a player outside the top 100 in seven years.
It means after winning four consecutive grand slams between 2015 and 2016, Djokovic has now gone three tournaments without adding to his tally of 12 major triumphs.
And following his early exit, Sport360 looks at other occasions where the Serbian has exited major tournaments early - since 2008 - acknowledging the 29-year-old's ranking status and position towards the top end of the men's game at the time.
