"I was very, very focused," Nadal said. "I'm very happy with everything and to have another chance on Sunday." That chance will be against 24th seeded Argentine Diego Schwartzman for a place in the quarter-finals. Third seed Dimitrov, who could meet Nadal in the semis, had plenty to prove after a huge second-round fright from a qualifier, who pushed him to five sets. And the Bulgarian delivered in a testing 6-3, 4-6, 6-4, 6-4 win over Russian rising star Andrey Rublev as temperatures touched 40 Celsius (104 Fahrenheit).

"These are the most important matches for me, when things are not working for me and I find a way," he said. "I'm feeling good physically, the heat didn't scare me at all today, so that's a good sign." He will next face the winner of an intriguing night match which pits Australian Nick Kyrgios against French veteran Jo-Wilfried Tsonga.

In a tournament shorn of seeds, 81st ranked Petra Martic also swept into the round of 16, celebrating her 27th birthday by holding off a gritty three-set challenge from Thai qualifier Luksika Kumkhum. Her reward is a match against Belgium's Elise Mertens, who beat struggling Alize Cornet of France in two tough sets. Cornet was among players wilting in the heat, with a doctor taking her blood pressure early in the second set as she succumbed to the baking weather.
Question: What did you take from that experience today?@marta_kostyuk: Well, a lot. How much you have to pay Svitolina to have one-hour lesson, so I got it for free.#AusOpen??? pic.twitter.com/9OjX4YnznU— #AusOpen (@AustralianOpen) January 19, 2018
