Dutch qualifier Kiki Bertens defeated Mariana Duque-Marino of Colombia 6-2, 6-2 to win the Nuremberg clay-court tournament on Saturday.
The 89th-ranked Bertens, who beat top-seeded Roberta Vinci in the second round and Germany's Julia Goerges in the semifinals, converted 11 of her 17 break points.
It's Bertens' second career victory after her victory in Fes, Morocco in 2012.
Duque-Marino, who had to play two matches on Friday, was chasing her second title.
The tournament is a warm-up for the French Open that starts on Sunday in Paris.
