Estonia's Anett Kontaveit beat fourth seed Maria Sakkari 6-2 7-5 to claim the Ostrava Open title.
It is a second title of the season for the world number 30 - who did not drop a set all week in the Czech Republic - following her win in Cleveland in August.
Greece's Sakkari is still searching for a first tournament win since victory at Morocco's Rabat Grand Prix in May 2019.
She was knocked out of the US Open by Emma Raducanu in the semi-finals.
The 26-year-old also reached the 2021 French Open semis but was defeated by eventual winner Barbora Krejcikova over three sets.
