Kyle Edmund is having problems with his left foot, looks like a touch of the blisters, and he's called for the trainer to stick some special plasters on.

Busta is waiting patiently, running on the spot to keep loose, before attempting to serve for the first set.

Kyle Edmund is 22 minutes into his second-round match and on the verge of losing the first set to Pablo Carreno Busta.

The Briton hasn't really got his game going yet while his opponent is serving very well.

Naomi Osaka tees it high and lets it fly - a kind of John Daly from the serve oche.

Konta's strings get stretched all out of shape and she clumps long to fold out of the game to 30.

Johanna Konta grips her fist and gives it the old "C'mon' as she summons an ace - taking advantage of some sluggish baseline movement from Naomi Osaka - to seal the game.

That was a hold to 30. That was the first return game that Osaka really got her teeth into.

It's important that Jo gets on the front foot in the rallies and not let Osaka dominate because Osaka can be very dangerous if she is given the chance.

Johanna Konta works up two break points via a zippy forehand down the line.

Here comes the first. Osaka comes to the net, there is a corridor of space for Konta to hit, but the net swallows up her forehand.

The second? Konta loads up on return and overcooks wide.

Osaka makes good her escape from deuce despite duffing a bounce smash and having to get out of jail with a dinky drop volley.

Kyle Edmund makes a few sloppy errors and is broken in the third game.

The Briton has it all to do in the opening set now after the Spaniard holds his serve.

The Johanna Konta serve is rock-steady and pin-point accurate.

The Briton muscles away successive aces - both kickers out wide. Osaka whiffs a racquet at both, but succeeds only in fanning the Melbourne midday air.

Eight out of nine first serves in for Konta already.

Naomi Osaka's serve is a monster, but it does slip the leash on occasion.

She is landing at 58% in her first two games, but her slugging groundstrokes provide enough cover to get her across the line.

Jo Konta skiddadles into the net, draws back her racquet head and clatters away a forehand to wrap up her opening service game.

First game on the board for Naomi Osaka.

The teenager's mother is Japanese and father is Haitian, but she moved to the United States at a young age.

She is attracting a load of Japanese press interest and is slowly picking up the language.

Judy Murray on Radio 5 live sports extra: "I love how much Andy supports the other British players, including the girls. He takes that figure-head role very seriously.

"It's wonderful to have so much British interest around the courts. I have been coming here for many years when there's been a dearth of British players but that's not the case this year."

Kyle Edmund is ranked lower than his opponent but it's a great opportunity for him. He has started well and proven he can handle the hot conditions here in Melbourne.

He's getting the job done, there wasn't much fuss in his first-round win, but he got the job done very professionally.

Over on Court 13, Yorkshire's Kyle Edmund is warming up.

It shouldn't take too long. It is a toasty 18 degrees Celsius and rising in Melbourne. A whole different kettle of fish from Beverley.

Pablo Carreno Busta - the 30th seeded Spaniard - is the man on the other side of the net.

Judy Murray on Radio 5 live sports extra: "Konta has had a great start to the year which is good to see after she split up with her coach and lost her sports psychologist who has been key to her rise in the rankings."

Naomi Osaka is only 19 but is already ranked inside the top 50, is very aggressive and loves the big stage. This is only her fourth Grand Slam but she has so much potential. 

Alarm bells should be ringing for Konta. This could be a very exciting couple of hours.

After dispatching former world top-20 player Kirsten Flipkens in the first round, next up in Johanna Konta's 2017 Melbourne Park campaign is Naomi Osaka.

Osaka, 48th in the world, has a jumbo-sized game with a massive serve and slugging groundstrokes.

The players are out on court and BBC Radio 5 live sports extra is pumping out the commentary from Down Under.

The Australian Open is a pretty good yardstick by which to measure Johanna Konta's surge to prominence.

In 2015, ranked 144th in the world, she lost in the first round of qualifying.

In 2016, ranked 47th in the world, she went all the way to the semi-finals.

This year, ranked ninth in the world, she is arguably the form player in the women's game.
