Johanna Konta hit back from the loss of the second set to beat Saisai Zheng in the quarter-finals of the Bank of the West Classic on Friday.
The British No 1 was made to battle hard before securing a 6-2 4-6 6-3 victory over her Chinese opponent in Stanford, California.
The third seed started strongly and broke her opponent twice in the opening set but Zheng levelled in a scrappy second set which saw serve broken seven times.
Konta broke early in the third before Zheng rallied with three straight games, but another break saw the Briton move into a 4-3 lead.
She held serve before breaking Zheng for a third time and then held on to secure victory in just over two hours 20 minutes.
In the semi-final, she will face second seed Dominika Cibulkova after the Slovakian rallied from 2-5 down in the opener to win 11 straight games en route to a 7-5 6-0 victory over Japanese fifth seed Misaki Doi.
Top seed Venus Williams, winner of the tournament in 2000 and 2002, beat 17-year-old wild card CiCi Bellis 6-4 6-1 to set up a last-four meeting with fellow American Alison Riske, who was leading 6-3, 0-1 when fourth-seeded Coco Vandeweghe retired from their quarter-final with an ankle injury.
