Defending champion Novak Djokovic survived an injury scare and battled past American Taylor Fritz to move into the last 16 of the Australian Open.
World number one Djokovic took the opening two sets but was then hampered by a side injury that restricted his movement, although he still recorded a 7-6 (7-1) 6-4 3-6 4-6 6-2 victory.
Djokovic is set to meet 14th seed Milos Raonic in the next round, but said: “I know it’s a tear and I don’t know if I will recover from that in two days. I don’t know if I will step on court.”
The Serb, who is chasing a record-extending ninth men’s singles title in Melbourne and a third in a row, added: “This is one of the most special wins in my life.
“It doesn’t matter who I was up against or at what round, to pull this through is something I will remember for ever.
“In the third and fourth set I just served and couldn’t do much with the returns. I was just putting in two first serves.
“I just tried to stay in there. I was hoping that whatever is happening is going to feel better and towards the end of the fourth it started to feel better.”
Djokovic hobbled between points, clutched his side and received medical treatment, but 23-year-old Fritz, the 27th seed, could not take advantage.
Canadian Raonic moved into the fourth round with a win over Hungary’s Marton Fucsovics.
