Oohs from the crowd as Nadal produces a breathtaking backhand return to reduce the deficit to 30-15 and the spectators are cock-a-hoop as the third seed shuffles his feet, looking a little unsteady but comes up with a forehand winner into the corner. Coach Toni looks at the gentleman sitting next to him and nods in approval. This could be a straight-sets romp for Nadal.

Nadal lost only four points on his own serve in the first set and his dominance continues at the start of the second. He nets a straightforward backhand, and it's a hold to 15 for the Spaniard who is keeping the points short by serving with aplomb.

This first set will not last for long because Nadal has two set points and he only needs the one. Nadal looking far more comfortable today than he did in the previous round.

Nadal going through is idiosyncratic routine... the bounce, bounce, bouncing of the ball... the tug of the pants... Showmanship from Sela and he has the crowd purring as he bamboozles Nadal with a pirouette and a quick-as-a-flash backhand. It's another trouble-free hold for the Spaniard, though, as he marches towards first-set victory.

Sela having to fight and stretch and brawl for every point, but it is something he is willing to do and he gets his rewards with a hold to love. His first hold of the match and he skips towards his chair for the changeover with the crowd's applause ringing in his ears.

So, Andy Murray is through to the last 16, but - with his Wimbledon conqueror Grigor Dimitrov up next - will that be the end of the line?

A frustrated groan from Sela as his looping forehand drifts over the tramlines. Playing one of the greatest players in history already messing with the underdog's mind. On the other side of the net, Nadal is as clinical and tigerish as ever, concluding a simple hold with his first ace of the match.

Warm applause for Sela as he launches an ace down the middle, and the world 106 has the crowd whooping and whistling on the next point, pouncing on a Nadal crosscourt forehand like a panther and replying with a whipped winner. But 30-30 is as good as it gets for Sela - Nadal breaking with an exquisite forehand winner.

Dark shades needed for those looking at Nadal. The Spaniard has opted for a bright pink t-shirt - a shade which was last worn in public on a regular basis in the 80s - combined with a radioactive yellow headband. If you can't beat your opponent with brutal groundstrokes then dazzle him with colourful attire.

Plan A is currently working for Nadal, though, with the Spaniard overpowering his opponent - sealing a comfortable hold with a ruthless winning forehand.

A nervous start for Sela, and understandably so, as Nadal collects three break points. But the 29-year-old starts to swing loose and free from the baseline, a classy forehand winner down the line the pick of the bunch as he levels to deuce. A fourth break point for Nadal thanks to that lassoed forehand of his, but we're back to deuce again. Break point number five. Nadal breaks. On we go.

Rafael Nadal was nearly booted out of the tournament by qualifier Tim Smyczek but the Spaniard came through a thrilling five-setter to reach the third round. The third seed needed treatment for stomach cramps during that match so has he recovered from whatever was troubling him? We're about to find out.

For those of you not in the know, Dudi Sela is a 29-year-old Israeli ranked 106 in the world. He has yet to win a title and should he beat Rafael Nadal (no sniggering, please) it will become the first Israeli man to reach the last 16 of the Australian Open since 1992.

But before we focus on Nadal's first meeting with 29-year-old Sela, let's focus on what has already happened in Melbourne today. Basically, it's a case of Murray through but Federer out.

British number one Andy Murray saw off Portugal's Joao Sousa in straight sets. Phew, I hear some of you say, but should the Scot reach the last eight he will not face Roger Federer because the 17-time Grand Slam champion was beaten 6-4 7-6 (7-5) 4-6 7-6 (7-5) by Andreas Seppi. A shock, you could say.

Sharapova's day in Melbourne Park is done and successfully dusted, which means Rafael Nadal will soon appear on the cobalt blue court to take on the unseeded Dudi Sela.

So, Sharapova reaches the fourth round of the Australian Open for a fifth year in a row and for the ninth time in 12 occasions. Her last loss in the third round of a Grand Slam was at the 2011 US Open so the match unfolded as the bookies would have predicted.

Whoops and whistles for Diyas as she wins a point for 30-15 - the underdog's never-say-die attitude forcing Sharapova to net. A fourth double fault from Sharapova as we're even-stevens at 30-30, but the second seed grabs a match point and progresses to the fourth round with her third ace of the match. That was easy peasy.

Sharapova wipes her mouth with the back of her hand, pausing for a moment as she tries to fathom a way of overhauling Diyas who is 30-15 up. Whoa! Cat-like reflexes from the second seed, stretching at the baseline to scoop the ball from her shoelaces and subsequently producing an incredible forehand winner. Another stunning winner from the Russian - her 21st of the match - brings up a break point.

But, surprisingly, to deuce we go, though Diyas can't kill off Sharapova. The 21-year-old comes to the net, plonks a forehand into the tape, presenting Sharapova with a second break point - which she this time takes as Diyas balloons a forehand wide to put the second seed within touching distance of victory.

Sharapova cruising down a street called easy as she collects three points in succession without much fuss. The crowd clap in approval as Diyas flicks her wrists, hops on the front foot, and produces a crackerjack of a winning return. At 40-30 are seeds of doubt being sown? Well, that could have been the case had Diyas, racing towards the net, not flapped at a simple-looking volley.

At 0-30 Diyas is at the bottom of the mountain, having to reach the top on a miserably foggy day in flip-flops. Impossible? Dangerous? It should be, but the 21-year-old drags herself level and skips 40-30 ahead before Sharapova drags the game to deuce.

Sharapova with a break point but a spirited figthback from Diyas, coming out on top of a baseline bashing, proves she has plenty of fight left. Some clumsy mistakes from Sharapova as the pair flick from advantage to deuce before we end up at break point and Sharapova takes it.

There's nothing to see here, no dramas to write about except for a dodgy double fault - Sharapova's third of the match - at 40-0 before the second seed comfortably holds to 15.
