"Come on Coco," cries the American as Ruse comfortably holds serve yet again.

Oh dear. A double fault gives the Romanian a 0-30 lead in the fifth game of the second set.

Gauff takes the next three points but Ruse battles back to deuce thanks to another double fault from the American.

Oh, that's big. Gauff grinds her way to a gutsy hold and it prompts a show of support from the crowd.

Well then.

Iga Swiatek doesn't come out firing straight away, and a double fault hands Jana Fett three early break points.

Another good hold from Paul Jubb, who is doing a good job of maintaining his composure. Nick Kyrgios is back to chatting to himself asking why the surface is "so slow",

We're thinking at this point is any player going to take it to Swiatek and think they even have a chance?

That first set took just 34 minutes, and it felt as though half of that time was taken up by the final game.

Here are the numbers...

These are tough times for Paul Jubb. He's just lost the third set and we're at a second deuce on his serve at the start of the fourth.

It's like Iga Swiatek has never been away.

After pouncing to grab the first break of the third set, Kyrgios goes full Kyrgios as he serves out for a 2-1 lead.

He continues to shout 'good return' from his chair in the direction of someone who had been sat behind during the change of ends, before returning to the court and getting the crowd involved.

He asks for some help deciding where to send one of his serves. It works.

Another huge forehand from Swiatek sets up a third set point...

There's a noise of frustration from Jana Fett as she knows a backhand is going long the second it comes off her racquet.

A second set point to Swiatek, then - but Fett rushes the net and forces the error out of Swiatek to keep the game going.

A couple of crashing Ruse winners takes Gauff to deuce but the American holds her nerve.

The 18-year-old is having to dig deep.

That's better from Fett, who clenches her fist as she serves and volleys her way to the advantage.

Oh, that's another double fault, though...

We just mentioned Nick Kyrgios trying to showboat his way to the third set. He's not the first to do so at Wimbledon this year.

Watch below a clip from yesterday as Alejandro Davidovich Fokina showboats on match point in his first round Wimbledon tie against Hubert Hurkacz in a match he goes on to win much later in five sets.

There's more applause for Jana Fett as she finally gets onto the front foot on her serve, but Swiatek steps in to the court and fires forehand after forehand over before Fett goes long.

Kyrgios's serves are unstoppable in this game. Efforts of 136mph and 133mph are unreturnable and met by louder and louder roars from the Australian.

He then has three set points and tries to win it with a showboating 'tweener effort, but messes it up. It doesn't matter though as he converts the third set point. He was a set down, now he's 2-1 up.

Iga Swiatek latches onto a Jana Fett second serve and ends up slapping it into the net tape.

Deuce.

There's a quiet groan from the Centre Court crowd as Jana Fett dumps a serve into the net for another double fault.

A better serve out wide is enthusiastically applauded, but a blistering cross-court backhand from Swiatek hands the world number one a set point.

It's a bit scrappy. Swiatek is not really being challenged by Jana Fett.

Fett is just lacking the consistency - I am trying to work out what her tactic is and I can't see what's going on.

You get the feeling that the crowd want a bit more of a contest here - a pretty enthusiastic cheering of a deuce in that last game.
