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.
