Paris: Czech teenager Marketa Vondrousova reached her maiden Grand Slam final by edging out Britain's Johanna Konta in a nervy last-four clash at Roland Garros on Friday.
The 26th seed Konta served for both sets, but 19-year-old Vondrousova battled through 7-5, 7-6 (7/2) in damp and windy conditions.
World number 38 Vondrousova will face either eighth seed Ashleigh Barty or fellow teenager Amanda Anisimova in Saturday's final.
