Stanislas Wawrinka completed a 7-5 6-2 victory over Edouard Roger-Vasselin to lift the Chennai Open trophy on Sunday.
The top seed outclassed the 52nd-ranked Frenchman 7-5, 6-2 in the 90-minute final at the Nungambakkam Tennis Stadium.
It gave the Swiss No 2 a fifth career title and his second at the season-opening event.
The first set lasted an hour as both players held serve until the 11th game, when Wawrinka broke through with a backhand cross-court shot that left Roger-Vasselin stranded.
The Frenchman, playing only his second final in a 12-year career, lost his serve in the opening game of the second set and then again in the fifth game before Wawrinka served out the match with an ace.
The Swiss, who starts the year ranked eighth in the world, won the title without dropping a set during a bruising week in which six players, including second seed Mikhail Youzhny of Russia and third seeded Fabio Fognini of Italy, were sidelined due to injury.
"This is big for sure," said Wawrinka. "It has been an amazing week for me and put me in the right frame for the Australian Open.
"Winning in Chennai means a lot to me. I like the place and that is why I have played here for six years now. This is just the place I want to start the season from.
"Last year was very good for me and I hope this year will also be the same. I have practiced hard and tried to improve my game. This is just the first tournament of the year, I hope I can continue this way."
