British number one Katie Boulter came through a tough test against Chinese sixth seed Yue Yuan to win 6-2 5-7 6-2 and reach the final of the Hong Kong Open.
Boulter will play either Russian top seed Diana Shnaider or Canada's defending champion Leylah Fernandez on Sunday as she bids for a third WTA title of the year.
The second seed, who is currently 29th in the world but will move up to at least 23rd when the rankings are next updated, is aiming to add to previous tournament victories in Nottingham and San Diego.
