Daria Kasatkina won her fourth career title by claiming the St. Petersburg Ladies Trophy when Margarita Gasparyan retired due to a lower back injury trailing 6-3, 2-1 on Sunday in Russia.
In an all-Russian final, the 23-year-old Kasatkina became the first player to win two WTA tournaments in 2021, as she also claimed the Phillip Island Trophy in Australia in February. Kasatkina, who is ranked 61st in the world, is also the first player to win both WTA 500 events on Russian soil in her career.
Ranked No. 126, the 26-year-old Gasparyan is the lowest-ranked player to reach a WTA 500 or above final since Svetlana Kuznetsova was ranked 153rd as the 2019 Cincinnati runner-up.
Leylah Fernandez of Canada defeated Viktorija Golubic of Switzerland 6-1, 6-4 to win the Abierto GNP Seguros final.
In the battle of unseeded players, the 72nd-ranked Fernandez won 4 of 5 break points and outdistanced No. 81 Golubic on service points won percentage (61.2 to 50.9) and return points won percentage (49.1 to 38.8).
