The Austrian, who tied for 22nd in the Masters at Augusta National back in April, produced a brilliant performance on the final day to card a six-under par 65 at Le Golf National.
It was Wiesberger’s third European Tour title win, the two others coming in 2012.
Bernd Wiesberger won the Open de France as James Morrison, Jaco van Zyl and Rafael Cabrera-Bello qualified for The Open Championship.
The South African banked the biggest cheque of his career for his third-place finish, one ahead of two-time major champion Martin Kaymer, who appeared primed to post his fourth sub-70 round of a vastly-improved week until he double-bogeyed the last after finding water.
The Austrian went 4-for-4 in scrambling and connected for six birdies, five of which in a six-hole stretch to conclude his outward nine.
Below is a recap of the final day’s events (via European Tour).
“Well, I just hit a great shot down the fourth before the (thunderstorm suspension) horns were blowing and they took us off the course”, he said. I chipped in on the next and then holed a long putt and felt really comfortable out there.
Van Zyl did not let his advantage slip in such emphatic fashion, but a two-over round of 73 meant a cumulative eight under. “Had a great weekend, only one bogey, 66, 65, that’s not a bad score”.
“Bernd played too flawless today. Simple as that. He played fantastic”.
Van Zyl held a two-shot lead after 54 holes, but he made a nervy start to the final round with a bogey at the second and another at the eighth, and he parred every hole on the back nine to remain at eight under for the tournament.
It was a disappointing day for Victor Dubuisson, seeking to become the first home winner of the French Open since Thomas Levet in 2011.
Austria’s best golfer had four birdies in a row on his way to a five-under first half, which put him in the driver’s seat.
He eventually had a 75 to place in a tie for 12th.
