Latvia's Ernests Gulbis won his sixth career title and first on clay when he captured the Open de Nice Cote D'Azur on Saturday, just a day before the start of the French Open.
Gulbis, who won in nearby Marseille earlier this year, saw off Argentina's Federico Delbonis 6-1, 7-6 (7-5) on Saturday to maintain his perfect record in ATP finals.
The 25-year-old world No 19 took his claycourt record in 2014 to 12-4.
Gulbis put out defending champion Alberto Montanes in the semi-finals before taking 98 minutes to see off world No 45 Delbonis.
A quick start helped him in this one, breaking for a 3-1 lead and then going on to secure the set in 26 minutes.
His Argentinian opponent improved in the second set and saw off three break points, but paid the price for not being able to make the most of a 4-2 lead in the tie-break.
The unpredictable Gulbis will face Poland's Lukasz Kubot in the first round of the French Open where he reached the quarter-finals in 2008.
