Novak Djokovic defied more hamstring troubles to beat Grigor Dimitrov in straight sets and reach the fourth round of the Australian Open.
The nine-time champion required a medical timeout after he edged the opening set in a 7-6 (9-7) 6-3 6-4 win over the Bulgarian 27th seed.
Serbia’s Djokovic picked up the injury before the tournament and opted not to train on Friday to rest it.
“Every point, every game mattered,” the 35-year-old said on Saturday.
“Obviously I didn’t know how I’m going to feel physically, it was going up and down.
“It was an incredible battle, three sets over three hours.”
Djokovic is hoping to win a men’s record-equalling 22nd Grand Slam title at Melbourne Park and it seems his to lose after a large number of seeds fell in the early rounds.
Defending champion Rafael Nadal, who holds the record, had been deemed one of Djokovic’s biggest rivals for the title but he was knocked out in the second round after a hip injury hampered his performance.
Djokovic’s reward for his win over Dimitrov, in which he again sported heavy strapping on his left thigh, is a meeting with Australian 22nd seed Alex de Minaur.
“Every season counts when you come to the last stage, the last quarter, of your career,” he said.
“Obviously you start appreciating and valuing each tournament more because you might not have a lot left in the tank.
“I love the sport, I love competing. It’s been almost 20 years now of professional sport. I can’t be more grateful than I am.”
De Minaur beat France’s Benjamin Bonzi in straight sets to progress to the second week in Melbourne, while Danish ninth seed Holger Rune also advanced in straight sets against Frenchman Ugo Humbert.
Rune will play Russian fifth seed Andrey Rublev next, after he defeated Britain’s Dan Evans earlier on Saturday.
Americans Tommy Paul, Ben Shelton and J.J. Wolf also progressed to the fourth round, all in straight set wins.
