Bulgaria’s world No 3 Grigor Dimitrov struggled past young Russian Andrey Rublev into the round of 16 at the Australian Open on Friday.
Dimitrov, who needed five sets to get past an American qualifier in the second round, held on for a gutsy 6-3, 4-6, 6-4, 6-4 win.
He will next face either Australia’s Nick Kyrgios or Jo-Wilfried Tsonga of France for a place in the quarter-finals.
