(CNN) Czech teenager Marketa Vondrousova will face Ashleigh Barty in Saturday's French Open final with a maiden grand slam title on the line for either player.

The 19-year-old Vondrousova became the first teenager to reach a final at Roland Garros since Serbia's Ana Ivanovic in 2007 after she beat Briton Johanna Konta 7-5 7-6 (7-2) on the new Simonne-Mathieu court.

Australian Barty navigated a dramatic three-set match against 17-year-old American Amanda Anisimova , eventually winning 6-7 6-3 6-3 on Court Suzanne-Lenglen.

Friday's semifinals marked the first time two teenagers had reached the last four of a major tournament since the 2009 US Open as the women's bracket continued to provide wonderful entertainment in Paris.

With no play possible Wednesday because of rain, the semifinals were pushed to Friday -- the same day as the men's singles semifinals on the showpiece Philippe-Chatrier court.
