Anything you can do I can do better.

Emma Raducanu adds some extra oomph into her serves to race in to a 30-0 lead. This opening set is winding towards an epic finish.

Well that is rare! A hold to love and at a crucial time in this opening set.

Diane Parry seals things with an ace, and suddenly the pressure is back on the Brits.

But Raducanu grows into the game, and ultimately holds to 15 thanks to a volleyed winner at the net.

There's nothing in it so far. Over to you is the message.

A slower, nervier start to Raducanu's latest service game. But Parry can't capitalise on a couple of second serves and Raducanu, rather fortunately, leads 30-15.

Nope, not this time. Diane Parry is matching the Briton stride for stride and holds to 15 with a couple of serve and volley routines.

Emma Raducanu has found her rhythm now, firing in a delicious backhand crosscourt winner to take us to 15-15.

Is another break on?

Diane Parry just asks the question, making it 40-30 with two forehand winners.

But Emma Raducanu stays composed and fires in an unreturnable forehand of her own to level things up.

Raducanu's brilliant break back won't count for anything if she doesn't back things up with a hold.

Emma Raducanu breaks in absolute style with a passing forehand winner down the line.....on the run!

We're on serve again.

And again saved. This one with an ace.

We go on folks!

But the Briton will get another chance with another return winner.

Not this time as Diane Parry delivers a brilliant second serve which Emma Raducanu can't return.

Parry nets. Break point chance.

Raducanu forces another deuce with yet another stunning forehand winner down the line.

These two are playing some fabulous, hard-hitting tennis.

Parry wins a simple point to inch closer to the game, but then Raducanu steps up to a second serve and delivers an crushing return winner.

Deuce.

Too good from Raducanu, she's patience personified, chipping away at her opponent.

This time she gets over the line with a forehand winner of her own. It's 30-30, big point coming up.

The home fans aren't happy with Emma Raducanu, who isn't best pleased with a line call.

Back to the action and Diane Parry bruises to a 30-15 lead thanks to some brutal forehand winners.

A gift. Diane Parry gets the early break as Emma Raducanu double-faults.

Not a great start for GB.

Oh dear. Raducanu leaves the door open with a poor net approach and Parry easily dispatches a passing winner. 15-40. Two break points.
