Jodie Burrage made it through to the quarter-finals of the Linz Open but fellow Briton Katie Boulter was knocked out in Austria.
British number two Burrage beat Romania's Jaqueline Cristian 6-3 7-6 (7-5) to reach the last eight of a WTA 500 event for the first time.
She will play Jelena Ostapenko or Clara Tauson in the next round.
British number one Boulter, 27, suffered a 7-6 (7-2) 6-4 defeat by Anastasia Pavlyuchenkova.
In a closely fought contest, Boulter lost a first-set tie-break before Pavlyuchenkova broke her in the ninth game of the second set and then served out the match.
