Shenzhen, China (AFP) - It was seventh time lucky for David Goffin after the Belgian beat Alexandr Dolgopolov over three sets to win the Shenzhen Open on Sunday.

World No. 11 Goffin had tasted defeat in his last six finals, a bitter run stretching back to 2014.

But the 26-year-old made up for three years of disappointment with a determined display against his Ukrainian opponent to seal the title 6-4, 6-7 (5-7), 6-3 in just over two hours in southern China.

He added the Shenzhen trophy to the two crowns he won in 2014 in Metz, France and Kitzbuehel in Austria.

"This one is really special because you know it's always tough to come back from injuries," said Goffin, who retired from the French Open and missed Wimbledon with an ankle injury.

"I cannot be happier today."
