Johanna Konta is still not certain of qualifying for the WTA Finals in Singapore after Caroline Garcia reached the China Open quarter-finals.
Britain’s Konta holds the final qualification place for the eight-player season finale but can be overtaken by the Frenchwoman.
World number 15 Garcia saw off Alize Cornet 6-2 6-1 and plays Elina Svitolina next, who beat Elena Vesnina.
Garcia must reach at least the semis in China to keep her chances alive.
Konta lost in the first round in Beijing and has withdrawn from next week’s Hong Kong Open with an injury.
Elsewhere, Sorana Cirstea of Romania claimed a shock win over Czech number four seed Karolina Pliskova 6-1 7-5.
Cirstea will play French Open champion Jelena Ostapenko after China’s top player Peng Shuai retired with a knee injury at 3-0 down in the first set.
Barbora Strycova also booked her place in the quarter-finals courtesy of a straightforward 6-0 6-4 victory over Daria Gavrilova.
