Polish teenager Iga Swiatek has become the seventh unseeded player to reach the French Open final in the Open era after beating Argentine qualifier Nadia Podoroska 6-2, 6-1.
The 19-year-old Swiatek also reached her first major final.
The 131st-ranked Podoroska is the lowest-ranked woman to reach the last four at Roland Garros. She broke Swiatek in the fifth game of the second set to trail 4-1 but was broken straight back.
Swiatek will next face either two-time Wimbledon champion Petra Kvitova or Australian Open winner Sofia Kenin in Saturday's final.
