Laura Robson has become the first British woman for 22 years to reach a WTA singles final with victory over Sorana Cirstea in Guangzhou, China.
The Londoner, 18, beat the Romanian third seed 6-4 6-2 to match Jo Durie's 1990 run to the final in Newport, USA.
Robson will play Chinese Taipei's Su-Wei Hsieh on Saturday after the world number 53 beat fourth seed Urszula Radwanska 6-1 3-6 6-0.
Sara Gomer was the last Briton to win a WTA singles title in 1988.
Robson, who became British number one on Monday with a career-high ranking of 74, has maintained the stunning form she showed in winning a silver medal in the Olympic mixed doubles and then beating Kim Clijsters and Li Na on her way to the fourth round of the US Open.
The Briton, who won the junior Wimbledon title as a 14-year-old, employed new coach Zeljko Krajan after the Olympics and has since gone on the best run of her developing career.
After beating seventh seed Shuai Peng and second seed Zheng Jie on her way the semi-finals in Guangzhou, Robson had too much for third seed Cirstea on Friday.
The teenager survived three break points in the opening game of the match before taking charge, building a 5-1 lead, only for Cirstea to find her range and blast her way back to 5-4 down.
Her hard work was undone, however, as Robson finally earned two set points on the Romanian's serve and converted the first with a thumping forehand winner.
A heavy backhand return into the corner set up a break point early in the second set and the inconsistent Cirstea netted a forehand to put the Briton 2-0 ahead.
Robson looked to have done enough when she won an epic sixth game of the set, converting her sixth break point to move 5-1 clear, but once again failed to serve out the set at the first time of asking.
It did not signal a prolonged fightback from Cirstea, however, with Robson attacking the Romanian's serve to break for the sixth time in the match and wrap up victory after one hour and 30 minutes.
