We're now into the semi-finals, which means the pressure and tension has been turned up a notch. There will be live text commentary of both women's semi-finals on Thursday, with Ekaterina Makarova taking on Maria Sharapova in an all-Russian clash and Serena Williams facing Madison Keys in the battle of the Stars and Stripes.

From a British perspective, though, the big match starts at 08:30 GMT, when Andy Murray plays Tomas Berdych for a place in the finals. Tantalising. Mouth-watering. Tasty. Until then...

Djokovic's biggest fans are not in Melbourne, of course, but that does not mean they weren't watching the world number one. "Come on daddy!" tweeted, external Jelena Djokovic with a picture of the couple's son, Stefan.

Djokovic on his semi-final with Wawrinka: "I'm expecting a marathon like the last couple of years and I'm sure the both of us will give our best to perform the best possible tennis. We always ask each other the most of our abilities and entertain the crowd."

"I returned very well, tried to get as many balls back in play as I could," says Djokovic. "I felt I had a good chance from the back of the court. In some games I had to let it go and wait for the opportunities to present themselves.

"He's one of the rising stars, one of the three players challenging the best players in the world. He's already an established Top 10 player and I wish him the best for the rest of the season."

On Djokovic-Wawrinka semi-final

"Wawrinka can offer Djokovic more power in the groundstroke exchange, and has a brilliant backhand. He can get through Djokovic, who is still favourite but it's a tough one to call."

An ace to the wings brings up two match points for Djokovic. A double fault - his second of the match - delays the inevitable, before he concludes the match with a deep volley, setting up a semi-final tie with Stan Wawrinka. Djokovic raises his arm, Boris Becker stands to applaud.

Raonic's movement has undoubtedly improved and he has shown deft touches at the net at times, but he has not yet got the skill or the nous to compete with a player of Djokovic's calibre. The Canadian comfortably holds, but is heading towards a fifth defeat in five meetings against the Serb.

A medley of unpredictable serves from Djokovic allows him to serve to love and it would be some spade that gets Raonic out of this hole.

Djokovic getting his racquet to the majority of Raonic's first serves, it's as if the Canadian is hurling beach balls his way. At 30-30, Raonic is wobbling like a 6ft 5in radioactive yellow blancmange - screwing a forehand into the tramlines to present Djokovic with a break point.

Raonic has a trick up his sleeve. Well, a bazooka of a serve. But another loose forehand means another break point for Djokovic and the Canadian sinks like a soufflé. Djokovic marching into the semi-finals.

Raonic must hope that the tennis gods are in the mood for an unpredictable ending because, at the moment, Djokovic is in control and has the semi-final in sight. The Canadian has not thrown in the towel, he is still scooting around the court in an attempt to fetch everything that's thrown his way but it isn't quite enough to beat one of the greats.

Djokovic has his prey in sight and is about to go in for the kill. Cat-like reflexes from the Serb as his lightening returns increase the pressure on his opponent, forcing him to falter. Three break points... Raonic saves one, but it's a tall order for the Canadian to save two more. Djokovic bossing it from the baseline, Raonic into the tramlines and this could be the beginning of the end.

"Raonic has struggled to get any handle on the Djokovic service game. He's tried to be aggressive and that hasn't really worked."

Raonic has yet to collect a break point in this match and seems unlikely to do so in this game. Brilliant from both players, though... Raonic managing to send a forehand over the net while performing the splits on the baseline... the pair lunging from tramline to tramline... an intake of breath from the spectators... before Djokovic comes up on top. An entertaining hold to love for the Serb.

Four-time champion Novak Djokovic is showing why he is hot favourite to win a fifth title.

At 30-15, seeds of doubt are being sown and Raonic is mouthing something or other towards his camp after a limp forehand. The Canadian has played a few dodgy volleys in this match, but stoops to his shoelaces to not only beat Djokovic with a stonking volley but force the Serb to lose his footing and fall to the canvas.

Unconvincing from the eighth seed as he gifts Djokovic a break point, but his serve is his get out of jail card and the Canadian can proceed to go once more.

The force of the Djokovic forehand pushing Raonic onto his heels and the Canadian crumbles like a chocolate flake. A third deuce. A dreamy forehand winner from Raonic, though, followed by a boomer out wide and Raonic holds firm.

"Djokovic's serve is working really well at the moment. It is not the biggest serve in the world, but it's got a lot of variety and his percentages are very good. He'll be feeling very good about himself. It's an impressive display from him so far."

Djokovic keeping the points short, Raonic unable to pose any questions. The world number one collects three set points and needs just the one. It's all a touch too easy for the top seed and the match is unfolding as the bookies would have predicted.

A shame perhaps that Raonic faltered in the first game of this set, denying us drama and tension, because the Canadian has served with confidence since. Faced with having to serve to stay in the set, he holds to love.

The crowd quietly watching the match unfold, applauding politely when required, oohing and ahhing when given the opportunity. But in this set they have yet to be given a reason to break into ear-splitting roars. A business-like performance from Djokovic, but the Serb not quite at his explosive best - not that he has had to be.
