It's amazing what reputation can bring to a match. The nerves of getting through a first round, everything that goes along with it. It creates a different feeling on the court.

Wow. Another double fault from Solana Sierra!
Two break back points for Emma Raducanu... and Sierra misses a backhand. We're heading to a tie-break.

What a tussle that last game was. You felt the momentum was shifting towards Raducanu but some surprising errors.
You saw the celebration from Sierra. It meant a lot for her to get through that game.

Emma Raducanu did so well to get herself back into this set, but now it is very much back in Solana Sierra's hands.
Can the Argentine see this out now? There are signs that the 21-year-old is getting really tense, with a double fault following a loose forehand.

That's a surprising miss from Raducanu. She was in control of that rally. Sierra had to slice just to get back into the point to defend.
It was a routine rally ball. It looked fine but hits the net.

Emma Raducanu shuts down the break point - but Solana Sierra is all over the Briton's serve on the following point and drives a return down the line for another opportunity.
Raducanu, undoubtedly playing with a bit more confidence now, makes no mistakes with a forehand winner from mid-court, but Sierra won't go away.
The Argentine will serve for the match for a second time.

It was a very negative reaction from her, the way she was talking back to her coach after getting to 5-5.
It looks like she doesn't feel like she's got energy in her legs. She got away with it a bit in that last game. Sierra has had a wobble.

Sierra has looked wobbly in the second set, unforced errors creeping into her game.
That was a great hold. Raducanu has dug deep in this set to try and bring her level up.
She's piling the pressure on Sierra. I think she'll have a few swings at returns of serve.

The predominantly pro-Raducanu crowd on court 13 are enjoying this.

Really good fight there from Sierra. From 15-30 down, she's dug it out.
*Raducanu 0-6 3-5 Sierra
A groan of frustration from Emma Raducanu as she hits into the net. She hasn't given much away during this match so far but clearly she feels like she's quickly improving here and needs to take her chances.
The Briton pushes Solana Sierra all the way in the Argentine's latest service game, but Raducanu sends a forehand long to leave Sierra a game away from victory.
