Pieters and Detry took a five-stroke lead into the final round of foursomes. However, their lead was reduced by one when Detry missed a three-footer on the par-3 second.
Nevertheless, the Belgian duo had an eagle and two birdies on the rest of the front nine, making the turn with their five-stroke advantage intact. Australia's Marc Leishman and Cameron Smith pulled to within two strokes, thanks to holing out from the bunker for a birdie by Smith and a 12-foot par save on the next hole by Leishman.
If there was any doubt, Pieters' approach to four feet on the 18th set up a final birdie by Detry to give the Belgians a 23-under total of 265.
Speaking after he and his team mates victory Thomas Pieters told journalists that "We were both nervous at times, but to finish with a birdie was special”.
