Warren Bennett won his fifth Challenge Tour title of the year and his fourth in the past six weeks when he stormed to victory in the Russian Open at the Moscow Country Club.
A closing 64, which would have equalled the course record but for preferred lies being in operation, left him on 18-underpar 270 and seven strokes clear of the rest of the field.
Going into the final round two shots ahead, the 26-yearold from Watford started birdie-eagle to go five in front and from then on the rest were playing for the minor places.
As the sun shone over the majestic course, Bennett was out in 31 with two more birdies while collected three more in a homeward 33.
"I just ripped it down every flag," he said. "I had so many chances I could have broken 60. I'm just playing my best golf and this has to be the best of my five wins because of the way I played, the toughness of the course and by shooting 64 to finish. If this doesn't get me some sponsorship I don't know what will."
Joint second were Ricardo Gonzalez of Argentina who closed with 68, and Bennett's playing partner, Sweden's Max Anglert with 69, both on 277.
Bennett, who picked up the Challenge Tour's biggest cheque of the year, £14,619, cemented his position at the top of the rankings. He has now won almost £69,000 and is over £34,000 clear of all his rivals.
