Boulter v Sramkova
Mel South
Former British player on BBC TVThere's going to be aggressive tennis, that's for sure. I think the court surface helps Katie Boulter out here and she will look to get a bit of revenge over her opponent.
Definitely helps Boulter that she is coming out here 1-0 up, it's more excitement rather than pressure.

Raducanu 6-4 6-4 Hruncakova
Great Britain's Emma Raducanu, speaking on court after her 6-4 6-4 win over Viktoria Hruncakova:
"Every match is extremely challenging and as the tournament progresses it's more and more. It was a really tough battle because my opponent has a huge ball-strike and she plays much above her ranking. On these courts, it really suits her. But I was really pleased with how I composed myself and served it out in both sets.
"Both sides of hers come with extreme power and if you give her time to either side, she can really hit it. The tactic was to try to keep her moving and not let her get the first strike in. I did that well with my serving and starting the point and I'm really happy to come through that."
