The Frenchman’s 65th final round earned him a two-stroke victory.
From France Romain Langasque reversed a five-stroke deficit to win his first European Tour title and secure his US Open debut at the ISPS Handa Wales Open.
Langasque scored six birdies in a flawless 65 final at Celtic Manor to finish eight under par and two shots ahead of Finland’s Sami Valimaki, with England’s David Dixon and Matthew Jordan one shot down.
Sweden Sebastian Soderberg needed to birdie the 18th to force a play-off, but fell back into a tie for the fifth after turning his third shot into the water to run a triple-bogey eight.
Scotland Connor Syme, who shared the lead overnight with Soderberg, also found water on the latter to overtake Bogey and slip into a tie for eighth.
Langasque told Sky Sports: “I’ve been playing really well since the start of the week and just focused on my own thing, and I’m so happy with the way I played the last nine.
“I had so many birdie chances and the second shot on 16 and the tee shot on 17 were my two best shots of the week.
“It’s one of the first times that I didn’t really feel the pressure because I was really focused on each shot and the first time I felt pressure was the corner at 18 because I was looking to have a longer shot.
“It wasn’t easy because I was too close and the two putts were under pressure, but before that I was really cool. ”
The victory will take Langasque into the world top 100 for the first time and also secure a start at the US Open next month via the mini order of merit of the top five events of the UK Swing of the European Tour.
“In golf, anything can go so fast,” added the 25-year-old. “I’m really, really happy this is where we all want to be and now I will have some good opportunities and I will have to focus again and play my best golf.
“Playing my first US Open this year, the good thing is that without an audience there is less pressure to be my first. I am really proud of myself. ”
Valimaki held the absolute lead after an eagle on the ninth and again after a birdie on the 11th, but bogeyed the 12th and couldn’t find more birds in the home stretch.
“It was a good day, I just couldn’t find those birdies on the last nine and it let me down for the win, but obviously a great week,” said Valimaki, who won the ‘Oman Open in March.
“It’s a big bonus for sure to enter the US Open. It’s great, I’ve waited so long to get into the majors and now is the time. I’m going to go out there and try to win the tournament, like I do every tournament. ”
