(CNN) -- England's Simon Dyson fired a superb closing 66 to win the Alfred Dunhill Links Championship by three shots at St Andrews on Monday.
Dyson celebrates the biggest victory of his career to move to the top of the Ryder Cup points race.
One shot behind Luke Donald overnight, Dyson captured the biggest victory of his career with a 20-under-par total -- after grabbing birdies on six of the first seven holes in an outward 30.
The win means Dyson now leads Europe's Ryder Cup points race and is in the world's top 50 for the first time.
Compatriot Oliver Wilson and Northern Ireland's Rory McIlroy shared second position.
It was Wilson's eighth runners-up finish -- he has still to win on the European Tour -- while joint second was good enough for 20-year-old McIlroy to move up from third to first on the Tour money list with two months of the race remaining.
Dyson knew it could be a special day from his second shot -- a pitch to three feet that brought him level with Donald, who carded a 73 to fall back to seventh and has not won on Tour now for three-and-a-half years.
By the eighth tee, Dyson was already four shots clear and although McIlroy did cut it back to two by turning in 32 to the winner's 30, that was as close as he got.
Dyson added another birdie on the 12th and could afford to bogey the Road Hole 17th. McIlroy ruined his chances of winning by bogeying the 12th, 16th and 17th -- but his birdie on the last was huge for the money list battle.
Scotland's Richie Ramsay would have finished joint second but for three-putting the last. He eventually came home joint fourth to secure his Tour card for next season.
After just three career wins -- two in the Netherlands and one in Indonesia -- since he turned professional a decade ago, 31-year-old Dyson is finally delivering on his potential.
In August, his second Dutch win came with a course-record closing 63 but Dyson admitted even that could not top his final round here.
"There is no way this can't be the best," he told reporters. "This is like our fifth major, a massive tournament at the home of golf, and I've shot a 66 to win it."
