Forsstrom had looked on course for a straightforward victory on Sunday when he made two front-nine birdies to extend his one-shot overnight lead to three at the turn.

But things began to unravel on the back nine as the 34-year-old followed up a double bogey at the 10th with a bogey on the 12th to surrender the outright lead.

Dantorp then hit the front on his own with a birdie at the 13th, but Forsstrom bounced back with gains at the 14th, 16th and 17th to edge back ahead.

And despite missing the fairway on the last, Forsstrom gave himself another birdie chance there before settling for a par which was good enough to bring him a first win at this level.

Forsstrom's final-round 69 meant he finished the tournament on 17-under-par, one ahead of Dantorp, who shot a closing 67.

Dane Thorbjorn Olesen was two shots further back in third after posting a flawless 66 on Sunday.

"I won on the Challenge Tour in Belgium, so I think Belgium is good!" - Simon Forsstrom.

Forsstrom, who earned his DP World Tour card for this season with a two-stroke victory at the final stage of Qualifying School in November, also won in Belgium on the Challenge Tour in 2016 and revealed he feels at home there.

He said: "I think the course suits me very well, it's pretty tight and short.

"I won on the Challenge Tour in Belgium, so I think Belgium is good!

"It's pretty similar to Sweden, the trees and the grass, so I think I feel very at home here."

None of the three Australians, Maverick Antcliff, Jason Scrivener and Blake Windred, made the halfway cut.
