Britain's Heather Watson is through to the Poland Open quarter-finals, but compatriot Jodie Burrage's run is over.
Watson, 31, defeated Belarusian Yuliya Hatouka in three sets, recovering from losing the second to win 6-2 5-7 6-1.
The British number five will play her Belgian doubles partner Yanina Wickmayer in the last eight.
However, British number two Burrage, 24, fell to a 6-4 6-1 defeat by Italian world number 108 Lucrezia Stefanini in Warsaw.
Watson missed her first two match points when leading Hatouka 5-4 in the second set but produced a dominant finish after the Belarusian forced a deciding set.
