So who is Kyle Edmund's opponent, Denis Istomin?

The 31-year-old Uzbek reached a career-high 33rd in the world six years ago, but it was last year at this stage of the Australian Open when Istomin took the headlines after knocking out defending champion Novak Djokovic.

Currently sitting 60th in the world, the 6ft 2 Russian-born right-hander has been playing tennis since the age of five and boasts a degree in physical culture.

Oh, and he's a Real Madrid fan.

David Felgate on BBC Radio 5 live sports extra: "The seeds in this side of the draw are decimated, all gone, and Kyle is one of the reasons. It's tough to always back it up.

"But if we took this as a first round match, we would think it is a good draw for Kyle.

"I am going to say Kyle Edmund in three sets."

Monday's victory over Kevin Anderson not only gave Edmund a landmark win in Grand Slam terms, it also opened up an opportunity to make real inroads at Melbourne Park.

A flurry of surprise results have left the Briton as the highest-ranked player in his section of the draw, until the quarter-final stage at least.

His first-round victory went a long way to banishing thoughts of several matches that got away from the 23-year-old last year when he was in a winning position.

He is now presented with an opportunity to break new ground at a Grand Slam, with a run to the fourth round of the US Open in 2016 his best effort to date.

"I put a lot of time and effort into this sport," he said.

"It takes up a lot of your life. When stuff like that happens, you're disappointed. You want to fix it.

"At the end of the day, it's a game of winning - it's a business."

This is just the warm-up for later in the week - but it's pretty warm. Heading into the early afternoon the temperature is already nudging 30C and the deckchairs in Garden Square are starting to look less appealing than the trees that surround them.

"Four seasons in one day" is how Melbourne is often described, although everything is relative if you're visiting from the UK. What we do know is that over the next couple of days we are likely to be seeing on-court temperatures exceeding 40C. That will be a blow to some players' chances but if they can battle through, next week is expected to settle into a more reasonable run of mid-20s.

In the men's draw, top seed Rafael Nadal takes on Argentine Leonardo Mayer not before 03:00 on Rod Laver Arena, before third seed Grigor Dimitrov opens the night session at 08:00 against American qualifier Mackenzie McDonald.

Nick Kyrgios is also in action later, with the Australian 17th seed facing Serbia's Victor Troicki.

In the women's draw, Belinda Bencic, who knocked out Venus Williams, faces Luksika Kumkhum while second seed Caroline Wozniacki is soon to get started on Rod Laver Arena against Jana Fett.
