It puts the two-time victor who came through the European Tour Qualifying School in pole position to be named the Sir Henry Cotton Rookie of the Year, with just one more regular tour event left on the 2019 schedule in Portugal, this week.
Belgian Nicolas Colsaerts captured his first European Tour title in seven years on Sunday, winning the French Open by one shot after a final round of 72. Quite a turn of events for a guy who arrived in Versailles wondering if he'd have a full-time job next year.
Dane Hansen carded a closing round of 68 to finish one shot behind Colsaerts, with South African Coetzee at 10-under par after a level par round of 71.

Belgian Colsaerts was a member of the European team that came back from 10-4 down to complete the Miracle at Medinah in 2012, while two years later Welshman Donaldson hit a towering iron into the 15th at Gleneagles to secure the point that ensured the trophy stayed on this side of the Atlantic.
"It's been a long road".
"I'm in control of a lot of things, my striking, emotions... it would be wonderful to win this thing. I went through ups and downs for so many years now".
Having begun the final round with a three shot cushion, Colsaerts quickly established control with an opening hole birdie while Coetzee found the water off the tee, handing the 36-year-old a five stroke lead from the first. However, he trailed Coetzee by two with six holes to play, and then had to take a back seat to Hansen.More news: Thai King Vajiralongkorn Strips Royal Consort of Title, Ranks for Disloyalty
The world number 289 made three straight birdies at the start of the back nine, but followed those with a double-bogey on the par-four 13th and never fully recovered, finishing with five straight pars.
A birdie at 13 and a chip in eagle at the par-5 14 proved to be the difference even though he double bogeyed the 15. I don't know what happened on 17. but it was a bit of a surprise when I got on to the green. I thought it was slowly slipping away.
"My putter was pretty cold all day, which was the difference from the first three rounds". But like I said, when you hole the last putt like this, and you come out on top, it's really a special feeling. He made his Ryder Cup debut in 2012, when he had eight birdies and an eagle as he and Lee Westwood defeated Tiger Woods and Steve Stricker in a four ball match.More news: WikiLeaks founder Julian Assange denied extradition hearing delay
