David Goffin atoned for his defeat in the Japan Open final last year by winning it on Sunday, beating Adrian Mannarino 6-3, 7-5. The victory extended Goffin's winning streak to nine matches, including four in Shenzhen last week when he won his first title in more than three years. He lost last year's Tokyo final to Nick Kyrgios.
The Belgian stands at No. 8 in the ATP Race to London rankings. With the injured Novak Djokovic and Stan Wawrinka ruled out, 10th place will be good enough to secure a place at the end-of-season showpiece event.
Mannarino started slowly in his attempt to win a first ATP title. Goffin broke in the fourth game with a forehand winner down the line, and again in the seventh.
The Frenchman posted his first victory over a top-five opponent when defeating Marin Cilic in the semifinals. As in that match, he gained a foothold in the middle of the second set, breaking Goffin to lead 4-2.
However, Goffin immediately broke back, and again in the 11th game before serving out to love for the title.
"I've been serving well for a few weeks," Goffin said. "My second serve is really effective; my opponents don't attack me, so I'm ready to play the second shot."
Goffin has 33 hard-court wins this year, joint-top on the tour with Rafael Nadal, who plays the China Open final later Sunday.
Mannarino leaves Japan having equalled his 2015 career-best 28 wins in a season.
Also, Japan Davis Cup duo Ben Mclachlan and Yasutaka Uchiyama surprised hot favorites Jamie Murray and Bruno Soares 6-4, 7-6 (1) to claim the doubles crown.
