Czech Jiri Novak beat France's Anthony Dupuis in the BMW Open final to claim his first singles title in three years.
Novak posted a 6-4 7-5 victory to earn the first prize of £37,000 in this French Open warm-up event.
He has won three singles titles overall, with the previous having come in 1998 at Mexico City.
He last reached the semi-finals of a tournament at last year's Toronto Masters Series event.
Dupuis had beaten Morocco's Younes El Aynaoui in the semi-finals.

Shocked Novak said: "I was so surprised when I reached the final. I would never have thought that at the beginning of the week.
"I've been practicing hard lately and this is the result."
Defeated Dupuis refused to be downbeat.
"This week is a great memory for me," he said. "It's amilestone in my career."
