Emma Raducanu produced an encouraging display to reach the second round in Strasbourg as she continued to build momentum before the French Open.
The British number two, who accepted a late wildcard for the tournament, was in fine form in a 6-1 6-3 win over world number 17 Daria Kasatkina.
World number 43 Raducanu had not won a set in three previous meetings with Kasatkina but the inconsistent Australian failed to win a single service game.
Raducanu will face American Danielle Collins in the last 16 as she continues her preparations for the French Open, which begins on Sunday.
"I'm really proud of my performance - I was very aggressive and I maintained my focus in the second set when it was getting close," Raducanu, 22, said afterwards.
"I think I've been building towards this. It's a great feeling.
"As I spend more time on clay I'm beginning to like it more and more. I'm building my relationship with the surface."
After reaching the Miami Open quarter-finals in March and moving back inside the world's top 50, Raducanu chose to take a "physical and mental" break from competitive action.
