Australian Marcus Fraser has stumbled spectacularly as France’s Julien Quesne clinched the Italian Open by one shot on Sunday.

Fraser, the overnight leader, held a one-shot lead at the turn before three-putting the 15th and dropping another shot on the par-three 16th to eventually post a two-over 74 and finish equal ninth at nine-under.

Quesne secured his second European Tour title despite starting the final round four shots off the pace.

The 33-year-old went through the back nine in 31, picking up birdies at the 10th, 11th and 15th holes.

He then chipped in from short of the 17th green and putted from six feet for another birdie on the last to complete a closing 67.

That gave him a 12-under-par total and a one-shot win over Ireland’s David Higgins and England’s Steve Webster.

Home hope Francesco Molinari, who joined the Turin club when he was just eight, came home in 39 to finish seven under.
