Britain's number two Johanna Konta is through to the second round of the Nottingham Open after beating Magdalena Rybarikova in straight sets.
The 24-year-old, ranked 147 in the world, won 6-3 6-3 against the Slovakian, who is 88 places higher.
"I was expecting a tough match and that's what it was," said Konta. "I was just taking it one point at a time and trying my best."
Top seed Agnieszka Radwanska beat Russia's Alla Kudryavtseva 6-0 6-3.
Konta, who qualified for the French Open before losing to Denisa Allertova of the Czech Republic in the first round, has made it to the semi-finals in Nottingham for the last two years.
"I love the courts, I love that centre court, so I'm happy I got to play on that today and tomorrow as well.
"I've been having a good, healthy year so far and I've been able to play a lot of matches."
Fellow Briton Katy Dunne lost 6-1 6-2 to Olga Govortsova, of Belarus.
