British number one Johanna Konta beat American Victoria Duval 6-3 6-0 in the first round of the Nottingham Open.
Konta lost in the first round of the French Open but has risen to a best-ever ranking of 18.
The 25-year-old will play either fellow Briton Freya Christie or China's Zheng Saisai in the next round.
She started off very well so I had to dig deep," said Konta. "It was my first match on grass so I am glad to get another opportunity to play this week."
Konta is seeded second for the grass-court event, behind the Czech Republic's Karolina Pliskova.
There was also some British success earlier in the day as Tara Moore booked her place in the main draw with a 6-2 6-2 qualifying win over Shuko Aoyama.
British stars Heather Watson, Laura Robson and Naomi Broady are also all in the first-round draw, as is former world number one Caroline Wozniacki.
