Jamie Murray and Dominic Inglot face Feliciano Lopez and Pablo Carreno Busta in Saturday's doubles rubber.

The match is live on BBC Two and the BBC Sport website from 13:00 GMT, and we'll be back for then. In a bit!

Mike Child‏: I am genuinely astonished. What a win for Cameron Norrie. He might even have won this tie for GB, especially if Kyle Edmund is fit for Sunday. The future of British Tennis is looking good right now!

GB captain Leon Smith, speaking on court: "At two sets down you're thinking just keep fighting, keep pride and passion. It's amazing to see Cam, as a rookie, a debutant, actually wear the opponent down. We've had a lot of good moments in Davis Cup and this is one of them right now.

"I'm almost a bit lost for words. All you ask for is that they give their best effort and fight like hell. Cam fully deserves every bit of praise he gets."

Laura‏: What a win! 2 sets down. Thrilling from start to finish. My dog is looking at me like I’m a mad woman.

Cameron Norrie:

• is ranked No 114 in the world
• was playing his first professional match on red clay
• was making his Davis Cup debut
• was facing the world No 23
• had never played more than three sets before - only became a full-time pro last May

More from Cameron Norrie: "In the fifth set I went to serve and there was an eruption of noise and I thought this is an incredible experience. I'm so happy. Best day of my tennis career, 100%."

If you missed any of that, here's Cam Norrie securing the fourth set on his way to a stunning victory in Marbella.

The Davis Cup tie is level at 1-1.

This puts a whole different spin on the tie. The doubles is a 50-50 match and potentially Britain are slight favourites. Then going into Sunday, Kyle Edmund gets an extra day's rest...

Lord Greystoke: Norrie, Norrie, Norrie - OI, OI,OI

Paul Reaney: Is this Cam Norrie I'm watching or a mix of Sir Andy Murray and Tim Henman. Unbelievable guts and hitting!

Cameron Norrie, speaking on court: "I was nervous and had a streak in the second set where I couldn't get a serve but I pulled it together.

"I noticed he was struggling a little bit in the fourth set. I backed myself physically and mentally against the guy and I'm just chuffed to get through it. I wanted to keep the points physical and work as hard as I could."

It's really one of the most fantastic comeback performances. He could play until he's 40 and not have a better Davis Cup win than that. Spain away from two sets down.

You try wiping the smile off Cameron Norrie's face right now. The cat that got the cream!

He turns and applauds the British fans, who have been in fine voice throughout the day.

Grins and high-fives all around for a giddy looking Cameron Norrie.

He sits down, and Leon Smith looks at him and just goes "WOW" right into his face. That is an absolutely remarkable victory.

Forehand volley from Bautista Agut drops out, before Norrie stands tall and wallops a winner into the corner of the court.

There's a yelp of annoyance from the Brit as another big shot floats over the baseline, but he chips away a glorious backhand to draw the error out of his opponent.

Hello, two match points...

Cameron Norrie, the world number 114, who has never played in a professional clay court tournament, is about to serve for the match against the world number 23 and a Davis Cup veteran.

Here we go!

That is the double break!

Bautista Agut whirls his wrists but there's too much on that ball and it spins out. Cameron Norrie is going to serve for the match!

Down the line again from Norrie and it entices a weary backhand out of Bautista Agut, who flights the ball into the net.

It's 30-30 but then a one handed flamingo forehand from Bautista Agut drops long, and Norrie has the chance to go double break up...
