Moore, the second highest-ranked British player in the draw, behind Anne Keothavong, started well, breaking her opponent four out of five times in first set, but Cepelova struck back in the second, winning five games in a row after trailing 1-2, to force the match into a decider.

Broady was a 6-3, 6-3 winner over Lina Stanciute of Lithuania. Broady, the world number 279 said: "It was a tough first round. We're good friends and know each other's games well.
"I served really well and I think that got me through it. I've struggled with my confidence this year and haven't been winning many matches. A lot of the tournaments that I have played have had stronger draws, and it's been tougher to win and get my ranking up.
