Before Vaidisova took to the court South, from Surrey, became the first British woman since Jo Durie in 1992 to reach the quarter finals of the Sony Ericsson WTA Tour with a 6-2-6 6-4 6-4 victory over world No.78 Aiko Nakamura of Japan.
The 22-year-old was understandably delighted with her result. "I started off a little nervous but after I lost the first set I still had the belief that I could turn it around," she said.
"She was hitting a lot of lines in the first set but I've got an aggressive game and I knew I should be the one attacking.
"This means everything to me, I've worked hard all year with my coach and my fitness coach. It's amazing, I'm really pleased. I came in here believing I could do well here on grass."
South, who's now bidding to equal Durie’s semi final appearance in 1992, was brimming with confidence for her quarter-final contest against Yanina Wickmayer.
"She's aggressive and she'll be looking to hit a lot of balls but I believe I can beat anyone here. I've got the game on grass and I think I can beat her.
"I want to go a round further and build on my performance here this week. Obviously I've got to take it a match at a time and see how I go tomorrow, but I love the pressure out there and I hope to take it, and the confidence from this win, through to my next match."
