Iga Swiatek's backhand is a thing of beauty, particularly on a grass court.

The way she leans into it makes it so effective.

Mirra Andreeva has an high bouncing ball to attack at the net. She shapes to smash before just nudging it over to lead 30-15.

Andreeva is short with another drop shot and it's deuce.

The Russian has had to come through deuce on both service games now.

One small advantage you get from breaking serve to win a set is that you serve first in the next, and if you can keep winning your own service games, you can put a little bit of scoreboard pressure on your opponent.

Iga Swiatek recovers quickly from a double fault to cream a cross-court backhand for a winner, on her way to holding serve at the start of the second set.

Great Britain's Greg Slade is through to the semi-finals in the men's quad wheelchair singles event at Wimbledon.

The 23-year-old beat Chile's Francisco Cayulef in three sets on court 14.

Cayulef saved three break points in the eighth game of the deciding set to level the scores at 4-4 but after holding his own serve, Slade converted the second of two break points in the next game to seal the win.

He will face either Guy Sasson or Sam Schroder in the last four.

Mirra Andreeva is still trying to find some consistency from the baseline. A forehand balloons long to hand over advantage.

Andreeva fails to make a clean connection with her backhand and that's the hold.

Tough opening set for Liudmila Samsonova but Iga Swiatek was near perfect and it is hard to see her not winning this in straight sets. The eighth seed has been in good form on grass this year and appears to be peaking just at the perfect time.

Liudmila Samsonova left the court at the end of the first set so there will be a slight delay before we get going again on Court One.

After this match is completed, men's world number one Jannik Sinner will take on American Ben Shelton on this court.

Mirra Andreeva builds into Belinda Bencic's service game to lead 15-30.

Bencic reads Andreeva's drop shot and puts it away for a 40-30 lead.

But the Swiss goes wide with a forehand to take it to deuce.

An ideal start for the former world number one, who wraps up the first set at the first time of asking.

Iga Swiatek has impressed, most notably with her returns of serve, although she'll want to raise her percentage of first serves in (currently 42%).

She's also been helped a little bit by a tally of 18 unforced errors by Liudmila Samsonova.

We're 38 minutes in on Court One and Iga Swiatek has a set point.

Mirra Andreeva is just yet to find her groove on serve here.

She's spending an awfully long time studying which ball to use and doesn't seem 100% comfortable.

Tricky opening service game for her but she comes through.

Belinda Bencic is forced wide as she attempts to return a serve and can only send it long.

Much better from Mirra Andreeva with a 118mph ace to get the hold.

That should help to address some of those nerves.

This is the furthest 18-year-old Mirra Andreeva has been at Wimbledon - she has made it to the semi-finals of the French Open - but some early signs of nerves on serve.

A double fault takes it to 15-15.

Andreeva is short with a drop shot and it's deuce.

There's some venom behind an inside-out forehand winner from Liudmila Samsonova, who has already shown in the first few games that she can strike a very good ball.

But the Russian's unforced error count is creeping up - a 14th of the match gives Swiatek a 5-2 lead in the first set.

A positive start for Belinda Bencic at 40-0 but Mirra Andreeva starts to settle behind the forehand and gets in the game with a winner into the corner.

Bencic gets the hold on the next point.

Liudmila Samsonova was furious after dropping that game, just screaming towards her box.

And there's the first break!

Iga Swiatek gets a look at a second serve and takes control of the point, before Liudmila Samsonova slices a forehand into the net.

Mirra Andreeva won the coin toss and elected to receive at the start of this match.

It has been the most common choice on matches I've covered at Wimbledon this year.

I guess it gives you a free shot to begin and a chance to settle?

Belinda Bencic to get us going.

An animated Mirra Andreeva fulfilled her promise to take "revenge" on coach Conchita Martinez by turning cheerleader at her invitational doubles match at Wimbledon.

Andreeva took the opportunity to reverse their respective roles and could be heard cheering Martinez on, shouting things like "you'd better win this game" and "keep it up!" after each point.

On the intimate setting of court 16, the seventh seed sported a hat decorated with tennis-related pin badges and held a poster reading 'Let's go senorita!' and 'You are golden'.

Martinez was playing in the invitational doubles - an exhibition event pitting former professional tennis players against one another - alongside former British number one Greg Rusedski.

After Andreeva booked her place in the last eight at the All England Club with victory over American Emma Navarro on Monday, the 18-year-old said she was looking forward to getting her own back on former Wimbledon champion Martinez.

Having joined forces last season, the two have a clear mutual affection, with Andreeva often teasing Martinez in her post-match interviews.

The first time that Iga Swiatek has got to deuce on Liudmila Samsonova's serve in this quarter-final.

Samsonova sends a backhand wide into the tramlines and now the eighth seed has a first break point of the match...
