A brief pause in play as a bug of some kind trundles across the baseline as Boulter is preparing to serve.

Umpire Tom Sweeney hops down from his chair to remove it.

A big service game for Kichenok, who won the 2024 US Open doubles title alongside Jelena Ostapenko and the 2023 mixed doubles Wimbledon title.

She takes the hold to 30.

Tough going for the Brits and Kichenok and Routliffe take the opening set at the first time of asking.

Can Boulter and Raducanu regroup in set two?

Boulter misses a simple put-away at the net before Raducanu double faults and that hands Kickenok and Routliffe two set points.

There's not quite as many smiles and laughs from the British duo. This is certainly a tougher task.

Both Kichenok and Routliffe have won Grand Slam doubles titles.

Good play from Boulter at the net.

The pair look to be easing into this one and getting more and more confident.

But the experience of the top seeds is shining through and they take another hold to put themselves within one game of the opening set.

Good stuff from the British pair!

They come through a tricky service game to take the hold. Can they make a dent in the serve of Rouliffe here?

Better serving from Boulter gets the Brits to 30-0 but the top seeds draw level when Raducanu hangs in the rally, chasing back and forth but eventually Routliffe places it out of her reach.

That's unlucky.

Boulter and Raducanu kept pace with the top seeds throughout that game but Routliffe's smash volley at the net wrongfooted Raducanu and they take the hold.

Hello.

A double fault from Kichenok and a brilliant put-away at the net from Boutler offers the pair a glimmer of hope at deuce.

Raducanu's turn to have a go at serving.

A couple of tense rallies in there but when she can nail that first serve the British pair really have a chance and they're all smiles as they finally get on the board when Boulter taps over a drop shot at the net.

It looks like Boulter and Raducanu are having a little tactics talk at the change of ends.

Is the competitive edge starting to take over?

The British pair are still full of smiles despite that early break of serve.

Of course this is only their second match playing together. Boulter said the other day that they have come close to playing together in Madrid and Miami so perhaps this is a partnership we'll get to see more of going forward.

Kichenok and Routliffe hold serve to consolidate that break and Boulter and Raducanu are yet to get on the board.

Boulter will be disappointed with that after her serving woes yesterday.

Kichenok and Routliffe take the break at the first opportunity with a strong forehand through the middle after a tense rally.

Boulter is up to serve for the British duo, she struggled with her serve a little bit in her singles match yesterday so will be seeing this as a good chance to practice.

A double fault brings up two break points for Kichenok and Routliffe.

Good start by Boulter and Raducanu and once again we're seeing that combination of Boulter's powerful ground strokes and Raducanu's agility at the net pair well.

They manage to earn themselves a break point but Boulter hits long before shoving one into the net and Kichenok and Routliffe hold.

Boulter and Raducanu have almost got matching outfits on for this.

Both in the burgundy, long sleeve tops and skirts.

They worked well together on Monday but they face a trickier challenge here against the top seeds.

It's absolutely packed on court one as once again 'Boultucanu' are playing on the smaller more intimate court.

It provided spectators with some lovely moments the other day with Raducanu chatting to the crowd as she filled her water bottle and the pair laughing and smiling throughout.

Once again fans have been queueing up to get a glimpse of the doubles duo.

Almost under way.

Unfortunately, you won't be able to watch Emma Raducanu and Katie Boulter's doubles match but I am here to provide you with live updates from court one.

Raducanu has only played two doubles matches on the WTA Tour in her career, one of them being on Monday with Boulter. But as the two tussle for the British number one spot in singles, Raducanu was asked whether she would be taking the lead in the partnership now that she is, for now, higher ranked than Boulter.

"No! She still has more doubles experience, so she can still tell me what to do, and I try and execute like yesterday [Monday]," she said.

The pair complemented each other well with Boulter's powerful groundstrokes and Raducanu's put-aways at the net.

Impressive wins for Britain's number one and two players in the singles yesterday.

And today they're back as a pair with a tough task against the top seeds ahead of them.

Fondly nicknamed 'Boultucanu' the pair looked like they really enjoyed themselves out there on Monday and Boulter is pleased with the nickname.

"I love it! I don't know if there is any other variations. I haven't actually seen. Maybe I'll have a little look on social media. I will have a look and see what's going on, but I like that name. It's a great name if it sticks," she said.
