Fourth seed Kenin of USA will meet 19-year old Swiatek of Poland in Saturday's final
Sofia Kenin defeated Petra Kvitova 6-4, 7-5 to reach the French Open final Thursday and will attempt to capture a second Grand Slam of the year following her Australian Open triumph.
Fourth seed Kenin will meet 19-year old Iga Swiatek of Poland in Saturday's final after denying two-time Wimbledon champion Kvitova in her bid for a third major.
The American faltered when serving for the match at 5-4 but broke Kvitova in the following game before closing out the victory over the Czech seventh seed.
Kenin, 21, will try to become the first woman to win two Slams in the same season since Angelique Kerber claimed the Australian and US Open titles in 2016.
Earlier, Swiatek became the first Polish woman in 81 years to reach the French Open final as she demolished Argentine qualifier Nadia Podoroska 6-2, 6-1.
The 19-year-old has yet to drop a set at the tournament.
The last woman to capture the French Open title without losing a set was Justine Henin in 2007.
Swiatek, ranked 54, has matched the run of compatriot Jadwiga Jedrzejowska who finished runner-up at Roland Garros in 1939.
She is only the second Polish woman to reach a Grand Slam final in the Open era after Agnieszka Radwanska at Wimbledon in 2012.
Swiatek becomes the seventh unseeded women's finalist at Roland Garros.
Of the previous six, only Jelena Ostapenko in 2017 went on to lift the trophy.
World No 131 Podoroska was the lowest-ranked semi-finalist in Paris in the modern era, and the first women's qualifier to reach the last four of the French Open.
She will rise to a career a best of 48th after the tournament, having arrived without a single Grand Slam main draw win to her name.
