Italy's Matteo Manassero has become the youngest winner of the PGA Championship after beating Simon Khan and Marc Warren in a playoff at Wentworth.
The 20-year-old birdied the fourth extra hole to edge 2010 champion Khan, after Scotland's Warren took three off the tee and then found the water at the first hole extra hole.
The trio ended on 10-under-par, one clear of Spaniards Miguel Angel Jimenez and overnight leader Alejandro Canizares.
England's Lee Westwood - who was two shots clear after four holes - stumbled to a 73 thanks to wild driving and slack putting to finish at seven-under-par.
On claiming his fourth European Tour title, Manassero said: "It's been an amazing week, I've always felt something special about this place and this tournament. I'm the happiest man in the world right now."
Khan, who is twice Manassero's age, came from seven behind in the final round with a closing 66 to set the clubhouse lead and faced an anxious 90 minute wait to learn his fate.
Manassero matched that score by the 13th, but could only par his way home for a 69 to join Khan. Warren, meanwhile, had four straight birdies from the 10th to edge into the sole lead, but dropped a shot at the 15th to make it a threesome at the top.
Canizares, playing in the final group with Westwood, missed an 18ft eagle putt on the last to join the playoff.
After Warrren bowed out, Khan and Manassero matched each other for two more holes, until Khan's hybrid approach fell just a few feet short of for the green, leaving Manassero a two putt birdie to win his first event since the Singapore Open last November.
Ernie Els, who oversaw a redesign of Wentworth's West Course, ended with a 67 to finish eight-under-par alongside fellow South African James Kingston and 22-year-old English rookie Eddie Pepperell.
Sergio Garcia finished five-under after a week of controversy following his ongoing spat with Tiger Woods and his "fried chicken" comment towards the world number one.
