Can Cristina Bucsa offer resistance amid this Emma Raducanu whirlwind she's been caught up in?

Raducanu is operating at a level above and looks to be enjoying every minute out there on Andy Murray Arena as she applies immediate pressure in the second set.

Two break points.

It's a scintillating opening set of tennis from Emma Raducanu!

The British number two holds serve to love for the second time in a row to extend her run of games to five and settle the first set in just 24 minutes.

Sonay Kartal and Jodie Burrage have lost the second set tie-break against top seeds Erin Routliffe and Lyudmyla Kichenok, exiting 7-6 (10-8) 7-6 (7-1) to deny the crowd an all-British doubles meeting with Emma Raducanu and Katie Boulter tomorrow.

On singles duty today, Raducanu is continuing her lightning fast, razor sharp start as she breaks again to move one game from the opening set here.

There's a swagger about Emma Raducanu as she walks from one serving position to the next on her way to completing a swift hold to love.

Cristina Bucsa, a former top-20 player, is no easy first-round tie, but Raducanu is motoring towards the first set with barely 20 minutes on the clock.

A huge smile stretches across the face of Emma Raducanu, who has quickly made herself at home on Andy Murray Arena!

The Briton gets on top of Cristina Bucsa's serve to force two break points, and takes the first to take charge of this one. A solid start becomes a very impressive one.

Emma Raducanu and Fran Jones are looking to complete a clean-sweep for Brits in the singles today following earlier wins for Katie Boulter and Heather Watson.

British number two Raducanu appears on course for a quick hold at 40-0 but is chased all the way to deuce before managing to serve her way to safety. Solid start.

Cristina Bucsa responds with a straightforward game of her own to set us up nicely on Andy Murray Arena.

Over on court one, Fran Jones is in action against McCartney Kessler but a break down to the American in the first set.

And on court five, Sonay Kartal & Jodie Burrage lost the fist set in a tie-break against Erin Routliffe & Lyudmyla Kichenok and are about to start another to decide the second against the top seeds.

Emma Raducanu will serve first as the sun shines brightly above the Queen's Club.

They'll be very pleased to see the British number two start like that, comfortably holding serve in her opening game.

Emma Raducanu appeared to really enjoy herself during her opening doubles match alongside Katie Boulter yesterday.

Having just seen her team-mate come through a tough challenge on Andy Murray Arena, the former US Open champion will aim to her in the second round.

Katie Boulter, speaking on Andy Murray Arena after winning her opening match at Queen's:

"I was battling really hard out there. I know how good Ajla is. She has made many quarter-finals at slams and she is very good on this surface.

"It is never easy coming straight from the clay to the grass and I'm just happy to get through and feel very grateful for all of you guys [for the ].

"It was really difficult. I did feel like I was battling my own mind at times, this surface can do that to you.

"I didn't feel like I served that great, and I have room to improve, but I'm just happy to be through to the second round.

"I came out yesterday to watch Andy get his first court [named after him], which is special in itself. To get the women back here [at Queen's] feels very special.

"It's actually something I dreamt of, having come here the last couple of years to watch the men play, so I'm just really grateful to be on this court."

Got it!

A stern test for the British number one but she beams and the crowd roar as she comes through it.

A hard-fought victory for Boulter.

Katie Boulter gets her grass court season up and running, in Katie Boulter fashion.

She lets out a deep breath as she prepares to chat post-match. We all need a bit of recovery time after that...

That's long from Ajla Tomljanovic.

Katie Boulter arrives at two match points.

Katie Boulter es Ajla Tomljanovic at the net for 0-30.

Two more points required for the British number one!

Katie Boulter has broken Ajla Tomljanovic's serve three times already in this set.

One more here puts her through to the second round.

Katie Boulter celebrates a first serve - there's been far too few of those of late - as she takes charge in her latest game, before a final winner gets her over the line from 40-30.

That is a huge hold for Boulter to put her within reach of the match.

It feels as though those Eastenders duff duff duffs have been going on for the past half an hour.

Who can find the extra gear to pull away here? Any level of consistency would do right now for either player.

Ajla Tomljanovic drives a backhand in on her way to securing her first hold of serve in this set, and we're all square again at 4-4.
