A moment of breathing space for Norrie. A very, very welcome hold to love.

Now, next task, chip away at the Nadal serve.

Norrie is having to work miracles to hold on to his serve, but can't make a dent into Nadal's and that's another routine hold for the 20-time Grand Slam champion.

We had three deuces, two break points for Nadal but Norrie comes up with an ace, his fifth of the match, for a hard-fought, but very handy, hold.

Norrie misses a chance to finish off with a smash, but he gets another chance to see off the break point and this time he does with a volley. That's two break points saved. Norrie holding on.

Nadal has a break point but a superb Norrie serve is wide of his opponent. But as soon as one break point goes, another comes after a forehand drifts wide off the Briton's racquet.

Cameron Norrie finds himself 15-30 behind in his opening service game of the third set. This is in danger of being very routine for Nadal after a tough first set.

By the way, check out Sunday's schedule for the Rod Laver Arena, although we still don't know if Djokovic is going to be able to play.

You will be feeling sad if you had bought tickets and now, because of the snap five-day lockdown, can't see any of this top-class action.

What a schedule of matches.

• WS: Garbine Muguruza (Spain, 14) v Naomi Osaka (Japan, 3)
• WS: Aryna Sabalenka (Belarus, 7) v Serena Williams (USA, 10)
• MS: Dominic Thiem (Austria, 3) v Grigor Dimitrov (Bulgaria, 18)
• WS: Iga Swiatek (Poland, 15) v Simona Halep (Romania, 2)
• MS: Novak Djokovic (Serbia, 1) v Milos Raonic (Canada, 14)

A missed volley from Norrie on the backhand and that helps Nadal take the first game of the third set.

It would be an optimist who would think Norrie could win the match from here. It's a steep climb.

The errors are starting to come a little quicker and a little more often for Norrie.

The first set was a close one, but Nadal has raced clear in the second and he is two thirds of the way to the fourth round.

Two set points for Nadal as Norrie is beginning to struggle to deal with the Spaniard's power and class.

It's a long, long way back now for Cameron Norrie, a set and a break down.

Nadal crushes a backhand down the line to ensure he consolidates that break of serve by holding his own.

The 2009 champion now just needs one game for a two-set advantage.

Cameron Norrie has done absolutely nothing wrong and he's lost the last six points.

Just too good from Nadal. Nadal powers one down the line, Norrie does well, stretching, to keep it alive but Nadal has the time and talent to blast a winner down the middle and that's the break he wanted.

Nadal nearly forced a break in Norrie's last game and now sniffs another one. 0-40 after a Norrie double fault.

But Nadal storms through the fifth game with a brutal, rapid hold to love.

Nadal is looking to put his foot down and race away with this one but full credit to Cameron Norrie. This is his first meeting against one of the 'big three' - Djokovic, Nadal and Federer - and Norrie is showing what he can do as he saves two break points to hold.

Oh this is some fantastic work from Norrie. Break-point down, he is very much on the ropes but Nadal can't land the knockout punch and that enables Norrie to gain position with a powerful forehand and charge into the net and Nadal can only stretch and send his lob long.

Two break points saved. Deuce.

A forehand down the line is out from Norrie after the Nadal defence is like hitting against a wall. That's break point for Nadal, but a beautiful forehand cut down the line from Norrie sees that one vanish. 30-40
