Krejcikova dedicated her victory to her mentor, the former Wimbledon champion Novotna who died of cancer at the age of 49 in 2017
Barbora Krejcikova won her maiden Grand Slam singles title at the French Open Saturday, beating Russia's Anastasia Pavlyuchenkova to become the first Czech woman in 40 years to conquer Roland Garros.
Krejcikova, ranked 33 in the world and playing just her fifth main draw in a Slams singles event, triumphed 6-1, 2-6, 6-4 for a second career title.
The 25-year old emulates compatriot Hana Mandlikova who claimed the trophy in Paris in 1981.
The 25-year old Krejcikova dedicated her victory to her mentor, the former Wimbledon champion Jana Novotna who died of cancer at the age of 49 in 2017.
Krejcikova was still outside the top 100 when the 2020 French Open took place last October.
In a nervy start to the final, Krejcikova was broken in the first game, serving up two double faults.
However, the 29-year old Russian was unable to capitalize and dropped the next six games as her Czech opponent grabbed three breaks and raced way with the opener inside half an hour.
Krejcikova was rewarded for her bold attacking, hitting 13 winners to the Russian's seven.
Pavlyuchenkova, who made her Slam debut back in 2007, was the more composed player in the second set, stretching out to 5-1.
A medical timeout at 5-2, during which she was seen munching Haribo gummy bears, merely delayed the Russian levelling the final.
In the decider, the players exchanged breaks in the third and fourth games, before the Czech broke to love for 4-3 on the back of a 10-shot rally.
Pavlyuchenkova saved two championship points in the ninth game and a third in the 10th but Krejcikova became champion on the fourth when the Russian hit long.
Both women capitalized on a draw in which the top seeds fell and just kept falling.
World No 1 and 2019 champion Ashleigh Barty hobbled out in the second round.
Serena Williams was knocked out in the fourth round, world No 2 Naomi Osaka withdrew after one match, while 2018 champion Simona Halep never even made it to Paris.
