Is there life in Sorribes Tormo yet? A couple of errors from Raducanu hand the Spaniard 0-30...
Nope! The Briton backs up a serve out wide with another volley before safely closing out the game.

This is silly! This level is silly! So many young players can hit a huge ball to be this consistent and to back yourself when a rally goes wrong... she has got so much court awareness.

Georgia Heath: Is Emma Raducanu applying for Bake Off because she's only offering her opponents bagels today?!...
Raducanu said she'd been enjoying the bagels in New York - smoked salmon bagels to be precise... There's another one for her today.

This is even better than we could have hoped for.
Sorribes Tormo 0-6 0-0 Raducanu*
Wow.
*Sorribes Tormo 0-5 Raducanu
I mean, what must Sara Sorribes Tormo be thinking right now.
A booming forehand winner takes Raducanu to 0-40 and three set points on the Spaniard's serve. This is breathtaking.
*Sorribes Tormo 0-5 Raducanu
Devastating tennis from Raducanu, who bullies Sorribes Tormo to the back of the court before executing another volley at the net.
A hold to love puts her within a game of the first set after 28 minutes.
Djokovic 6-7 (4-7) 3-1 Nishikori*
Novak Djokovic has got a bit of a grump on, but he's done well to stave off five break points and extend his lead over Kei Nishikori.

Emma is hitting Sorribes Tormo off the court.
Sorribes Tormo 0-4 Raducanu*
A stunning start from world number 150 Emma Raducanu.
Another break and it's 4-0 to the British teenager. Too good.
*Sorribes Tormo 0-3 Raducanu
This is Sara Sorribes Tormo's first appearance beyond the second round of a Grand Slam and she's second best on court 17 at the moment.
A loose backhand leaves her 15-30 behind on serve, and she can't get a hold of a big Raducanu forehand. Break point!
Laura Robson
Former British number one on BBC Radio 5 Live Sports Extra
I'm really pleased with the way Emma has come out here with no fear. Her attitute has been faultless throughout the tournament. She's clearly got some tactics in her head and is working through them as she figures out the match.
*Sorribes Tormo 0-3 Raducanu
Emma Raducanu finds herself 15-30 down on serve after a couple of double faults, but she recovers superbly and successfully turns things around to extend her advantage.
