Ten-time champion Novak Djokovic reached the Australian Open quarter-finals without striking a ball after his last-16 opponent Jakub Mensik withdrew on Sunday due to an abdominal injury.
His withdrawal means Djokovic will play Italian fifth seed Lorenzo Musetti or American ninth seed Taylor Fritz for a place in the semi-finals.
Unfortunate decision to make for me, said rising star Mensik, who beat American Ethan Quinn in three sets to set up the Djokovic clash.
