Oooh, ahhhh gasps the Centre Court crowd - any three of those shots in that rally between Nadal and Sela could have been winners. The fans like what they are seeing...that should bring the rest of them back from their lunches as there are still a few empty seats here.

British number one Kyle Edmund after his win over Alex Bolt: "Firstly I am just really happy to get through after that long preparation. There's a lot of build-up, excitement and anticipation. So to play well makes me happy. What a setting, my first time on Court One in singles.

"It was a tricky third set but shows how well I was playing to come back and win 7-5.

"It is great I can go out as British number one, it was a great experience.

"I am very hungry I always want do well. This is Wimbledon, my home tournament and is also happens to be the biggest in the world, so I'm hungry to keep pushing. The support was great, people are happy I won so they can get off to watch the match later."

On England at the World Cup: "You have to be positive. I am for the guys today. The way they played in the group stage, minus the Belgium game, it is anyone’s tournament with some of the top teams going out. All the best for England, hopefully they can do the nation proud."

We're up and running on Centre Court, where Rafael Nadal is being made to work by Dudi Sela.

The Spaniard gets the best of a 13-shot rally that saw him dashing and darting all over the court. It remains on serve in the opening stages.

On Court One next, what should be a belter of a match.

Petra Kvitova, the two-time Wimbledon champion and many people's favourites to take the title, will play the entertaining Aliaksandra Sasnovich.

Watch it here.

Here is the moment defending champion Garbine Muguruza completed her 6-2 7-5 win over Naomi Broady.

We saw excitement from Kyle Edmund, but also relief, that he was playing up to his capabilities. At the end he tightened up, but rose to the occasion and let it out. He needs to do that more and let the crowd know how much it means. It is such a hurdle as it is only his second win at Wimbledon.

And it's nearly time for Rafa to take centre stage on Centre Court...

Here is defending champion Garbine Muguruza after her victory over Naomi Broady: "Incredible, it is a beautiful court, to come back is always good and to enjoy this time more.

"I knew she had a big serve and big shots, on grass it is always difficult, I found the crowd very fair with each of us.

"I am pretty happy with my serve and controlling the emotions, in a Grand Slam it's always difficult, so I am happy with the way I am playing."

Right then, Jay Clarke, what ya got? The wildcard needs to produce something here to stay in the championships...

A double fault from Ernests Gulbis will be welcomed by the 19-year-old, but his return off the next point only finds the gutter.

Monster ace from Gulbis, his 19th of the match, before another wrist-wrecker.

Two match points Gulbis.

Up next for Kyle Edmund is either Japan's Yuichi Sugita or American Bradley Klahn.

He waves to the crowd as he wanders off, stopping on the way to sign a few autographs.

A deep return from Ernests Gulbis, and Jay Clarke can only coax it back into the tape.

The Latvian breaks, and is a service game from the second round.

A horrid shank off the top of Kyle Edmund's racquet has him looking at the floor in disgust - although the man sat above the scoreboard takes a smart catch.

It's 15-15 before Bolt, trying another serve and volley, flunks the ball into the net.

Oh, a cracking return from Edmund out wide, and it surprises Bolt, who dumps his return into the net! Two match points to Edmund.

Jay Clarke zips a leaping forehand wide.

Break point Ernests Gulbis.

The Derby teenager is still looking strong heading into the business end of the final set.

Jay Clarke throws a couple of kicking serves Ernests Gulbis' way, but can't quite skip around a deep, wide return quickly enough to coax it back.

Gulbis shows he can also turn on the pace when necessary with a passing winner, but in truth there was too much on that drop shot from Clarke.

Massive ace from the 19-year-old in response - 131mph, his quickest of the day - but miscues an overhead, backhand smash. That's deuce.

Alex Bolt has gone from serving for the third set to serving to stay in match.

Here he goes...

In other Brit news, Gabriella Taylor has just been comprehensively beaten in the first set by Eugenie Bouchard.

The 2014 finalist had to come through qualifying to secure her place at SW19 this year.

That's more like it from Kyle Edmund, as the British number one comes steamrollering forward to meet a Bolt drop shot and flick a winner past him.

A first serve overpowers Bolt before Edmund plonks a forehand into the side of the net, but another body serve puts the Brit up 40-15.

He holds.

Ernests Gulbis rattles to a 40-15 lead, but Jay Clarke puts the burners on to reach a drop shot and dinks it back over the net with the help of the tape to take it away from the Latvian.

Gulbis polishes off his hold with a storming serve.

Over to you, Jay Clarke...
