Raducanu has to work very hard for the next point, mixing things up. Chucking a slice in here and there, going back to some flatter forehands.

Eventually Vondrousova gets impatient and when she chucks a backhand out, Radders makes plenty of noise again, screaming "come on" as she turns to her bench.

She's upbeat after winning the next point too - to get on the board in the second set.

Marketa Vondrousova is going to up her game because the level of Emma Raducanu today has been really impressive.

Vondrousova needs to be more aggressive earlier in points.

A big key to this is that Raducanu needs to be able to sustain this level.

Raducanu's fully found her groove this evening. Bam. A double-handed backhand skids past Vondrousova at the net and clips the line. 30-0.

The first point of a new set. I like to call this one a tone-setter.

Ah, a double fault's not a great sign for Marketa Vondrousova.

She then errors a backhand, but quickly rebuilds and wins the next four points on the bounce to hold to 30.

Four-time Grand Slam winner Naomi Osaka is through to round three - Wimbledon hasn't been her favourite hunting ground but she sees off Katerina Siniakova 6-3 6-2.

Joining her in the last 32 is America's Amanda Anisimova, who completed a straight-set victory over Renata Zarazua.

Terrific intensity from Emma Raducanu, I love the sense of urgency that she is playing with.

Very impressive. The first set was so well executed. So many returns back in play. She is putting the pressure on Marketa Vondrousova - she broke her twice.

It feels like Emma is very clear on how to play, she is trying to produce some mistakes from Vondrousova and she has done that.

A top-class set of tennis from Emma Raducanu. She takes it after Marketa Vondrousova pops a backhand long.

Vondrousova won the Wimbledon title two years ago. But British number one Raducanu is making her look very ordinary.

Raducanu goes to the net but Vondrousova is clever and chips a wide passing winner. 40-30.

Slight groans in the crowd. Raducanu's run stops with a wide slice. 40-15.

Another ace. Three set points!

Uuuuuurrrggggghhhh. Raducanu puts all her energy, and voice, into her latest serve, which is a 110mph ripper. Ace. 30-0.

"Come on!" Raducanu is roaring again after she forces Vondrousova into an error.

The crowd are making plenty of noise with the Briton set to serve for the first set.

Deuce and, oh no, not at a time like this Marketa!

The Czech double faults to hand Raducanu another break point.

Top, controlling tennis from Vondrousova. She saves two breaks on the bounce, the last with a stunning cross-court backhand winner.

"Fault!"

A high-pitch cry from the umpire and Raducanu greets it with a fist bump. Vondrousova goes long and Raducanu goes up 15-40.

This for three breaks on the trot.

As the stands continue to refill, Raducanu’s breakthrough rightly brought the biggest cheer of the match so far.

The British number one had to remain patient, but that stunning winner was worth waiting for.

She’s celebrating her winners and the crowd are responding, but Marketa Vondrousova moves quickly to remind her that there are two Grand Slam champions on this famous stage tonight.

Incredible offence for Emma Raducanu first and then the defensive skills.

She found that passing shot when it didn't seem like there was much room.

Raducanu has come out with just the right balance of offence and defence.
