Petra Kvitova came from a set down against Mihaela Buzarnescu to win the Prague Open on home soil - her third WTA title of the year.
The Czech raced into a 3-0 lead but Romania's Buzarnescu took the opening set after winning five straight games.
But world number 10 Kvitova hit back before taking a hard-fought decider to win 4-6 6-2 6-3.
The two-time Wimbledon champion, who has now won 23 WTA tournaments, denied Buzarnescu her first career title.
Kvitova, 28, has had a strong season on the women's tour, winning both the Qatar Open and the St Petersburg Open, following six months out after a knife attack at her home in December 2016.
