Teenage qualifier Amanda Anisimova shocked number one seed Zhang Shuai at the Japan Women's Open to reach her first WTA final.
The American, who turned 17 a fortnight ago, becomes the youngest player to make a final since Donna Vekic, aged 16, in 2013.
In a match interrupted by two lengthy rain suspensions she won 7-6 7-5 in a one hour and 48 minutes.

The world number 227 produced a confident display, winning 85% of her first serve points to topple her Croatian opponent 6-3 7-5 and book her place in the semi-finals.
Pegula needed just one break of serve off the back of a double fault from Martic to close out the opening set, while the second set saw the pair exchange breaks
With the scores tied at 5-5, the American played aggressively to go 6-5 up before holding her nerve to serve out the match.
She will now face a meeting with compatriot Sofia Kenin, who reached the second WTA semi-final of her career by ousting number three seed Monica Puig.
