This is frustrating for Andy. A game ago I thought finally things are clicking for him, he's finding something extra, but a few unforced errors and he's break point down again.

The first break point is saved by Murray... and the second one too, thanks to a sweeping forehand which finds an angle. Deuce

Two break points Nishioka.

Nishioka at 15-30 on the Murray serve. That was unforced error number 44 from Murray.

Oh my. It looked like it was going to be a straightforward story on court five, with Johanna Konta firmly in control.

But a few unforced errors from the British number one have opened the door for Heather Watson.

With no fans in, you can hear all the shouts. "How many times have I practised that, this is killing me," says Murray after sending one long.

Nishioka holds his serve. 5-5.

From 3-1 down in the third set to 5-4 up. Murray was flirting with danger and had to save a break point, but he is able to do so and now finds himself one break away from taking the third set.

Konta finally gets her break!

The pressure gets too much for Watson's serve, which had held steady so far, and the younger Briton hits a backhand long to put Konta in prime position to take the set.

Andy gets so much criticism for his venting at his box but it fires him up and gets him going.

There's a lot of tennis left in this match if he can hold on in this set.

Konta had a couple of break points in the lengthiest game of the match so far but Watson showed great composure to hang on to her serve.

The British number one, on the other hand, dropped just one point on the way to her hold. She’s showing her compatriot what’s what.

Murray having to dig deep again. He's now 0-30 on his serve after nearly stumbling over his own feet as he tries to flick over a backhand.

An ace is next. 15-30.

A spinning backhand from Murray can only find the top of the net and that brings about the end of his run of three games in a row. Four games all, third set.

Amazing the energy boost that comes from a break back. Murray, who has his name on the roll of honour outside the stadium thanks to his 2012 win, moves ahead in the third set, albeit on serve.

With half the court covered in shadow, Murray dances out of the light and into the dark to jump high and send away a forehand winner early in the seventh game. Is that break back going to be the catalyst for an incredible turnaround?

There's life in this match after all. A rare unforced error from Nishioka and that helps Murray get the break back that he needed. We're back on serve. 3-3 in the third.

Jiten Chandarana: Even with very few people in the stadium, you can hear the noise when Murray wins a point. Everyone is desperate to see Murray do well in his comeback grand slam. Murray needs to scream or even better roar ‘Come on’ after a positive point and try and turn things around.

A serve out wide gets its reward as Murray holds his serve. There's been no anger, no tantrums, no trademark Murray fire today. He may just be trying to save his energy for the on-court action.

Or is he acknowledging the fact his body might not be letting him do what he did before? Saying that, we've all learnt not to write off Andy Murray over the years.
