Mannarino took the £3,700 prize money for winning in Jersey
French fourth seed Adrian Mannarino has won the £20,000 Jersey Challenger event after beating German second seed Andreas Beck 7-6 7-6 in the final.
Mannarino, who beat top seed Chris Guccione in the semi-finals, needed tie-breaks in both sets to win Sunday's final at the Les Ormes club.
"I've been lucky because in tie-breaks it's never easy," the Paris native told BBC Radio Jersey.
"It came down to only one or two points so I am very happy."
"It was a very good week for me, I was playing very well. I was a little bit lucky today and in my semi-final, but it was a very good result and a very enjoyable week for me," he added.
Beck made the final by beating Czech qualifier Tomas Zib in straight sets in his semi final on Saturday.
In the women's £6,700 tournament, Polish fourth seed Katarzyna Piter beat top-seeded Swiss Stefania Boffa 6-2 6-2 in the final.

"I really enjoyed the time I spent here, I played very well, and I won so I'm very happy," Piter said.
"I've won a $10,000 tournament and now I think I can play at a higher level, maybe a $25,000 tournament" she added.
And Piter says she would like to try her hand at the £25,000 tournament being held at the Les Ormes club next March.
"I heard there'll be one here in March, so I'll come back and play here again," she said.
