Great Britain's Heather Watson, who trains at IMG Academy, and Chang Kai-chen of Taiwan both reached their first ever singles final on the WTA Tour at the HP Open in Osaka.
The 20-year-old from Guernsey beat Japan's Misaki Doi in two tight sets – and Chang then stunned top seed Sam Stosur in a third-set tie-break. Watson's victory comes three weeks after Laura Robson became the first British woman to reach a WTA final since Jo Durie in 1990.
Watson took the first set against Doi, winning 7-2 in a tie-break after each player broke serve once. But like Watson's quarter-final win over Pauline Parmentier on Friday, Saturday's second set was littered with service breaks – an area Watson will surely have to improve on in the final.
Watson finally came through with a late fourth break against three for her opponent, wrapping up a 7-6 (7-2), 7-5 win in just over two hours to end the hopes of the home fans.
Stosur was the only woman among the final four who had previously reached a tour semi-final but quickly found herself a set down against world No134 Chang.
Stosur levelled the match but Chang, who knocked out Watson's fellow Briton Laura Robson on Friday, was not to be denied. After a break apiece in the final set she forced four match-points in the breaker, taking the second to win 6-2, 4-6, 7-6 (7-3).
