Gstaad - Victorija Golubic claimed a home victory at the Gstaad WTA tournament on Sunday, the Zurich player fighting back for a 4-6, 6-3, 6-4 defeat of third seed Kiki Bertens.
The world number 105 won the first title of her career in just over two hours as she overhauled her more experienced Dutch opponent.
Golubic denied 26th-ranked Bertens a second title this season as she claimed victory as the tournament returned to the calendar after a three-decade absence.
Golubic lost the first set but won the second, which was littered with six breaks of serve.
The 23-year-old Swiss went down a break in the first game of the final set but immediately broke back. She concluded victory as she broke Bertens in the tenth game as the Dutch player sent a return out.
