Robert Rock ended his nine-year wait for a European Tour title with victory at the Italian Open in Turin.
The Englishman, who held the lead from the first day, carded a final-round five-under 67 to finish on -21 overall.
Compatriot Gary Boyd holed eight birdies in a blistering round of 66 to finish one shot behind Rock alongside Denmark's Thorbjorn Olesen.
The victory means Rock has qualified to play in next week's US Open for the first time in his career.

The 34-year-old credited his maiden tour title at the Royal Park Roveri to his improved putting skills, courtesy from an old coaching manual.
"My putting had been letting me down so when I read the book I decided to use some of the tips in it," said Rock. "It helped me considerably."
The round of the day belonged to Olesen, who carded a phenomenal 10-under 62, including a 30-foot birdie on the 18th, as he heaped pressure on Rock at the top of the leaderboard.
Former teaching professional Rock had been trailing Olesen by four shots when he holed a bogey at the third following a nervous start.
But he soon found his composure, carding six birdies in seven holes to take the outright lead by the 11th hole.

However, a 15-foot putt for par on the 17th after driving into the trees proved just as vital as his seven birdies.
"That putt on the 17th took a huge amount of pressure off," he added.
Home favourite Matteo Manassero finished five shots behind Rock but the teenager will make his US Open debut alongside Rock at the Congressional Country Club in Maryland next Thursday.
