( CNN ) -- Italy 's Matteo Manassero became the youngest ever winner at the PGA Championship . He had to work hard for it . Manassero edged England 's Simon Khan on the fourth extra hole of a playoff after Scotland 's Marc Warren exited on the first extra hole . The trio had finished at 10-under 278 . Khan found the water with his second shot on the deciding hole in fading light at Wentworth , and when Manassero struck a birdie to clinch victory , he surpassed Bernard Gallacher as the youngest champion . At 20 years and 37 days , Manassero was two months younger than Gallacher when the Scot triumphed in 1969 . As a result of winning the European Tour 's flagship event , he 'll move from No . 57 to inside the top 30 in the world rankings , leads the Race to Dubai and booked a spot at this year 's U.S. Open . `` I feel unbelievable , really emotional , '' Manassero was quoted as saying by the European Tour 's Web site . `` It 's been an amazing week . I have always felt something really special about this place and this tournament . `` Everything has come together this week . I managed to play well and managed to stay in contention after a tough day on Friday and pulled it off with this playoff . '' The dramatic finish at Wentworth helped make up for the early departures of Rory McIlroy , the world 's second ranked golfer , and defending champion Luke Donald . Both missed the cut after underwhelming in the opening two rounds -- played in chilly conditions . The fans at Wentworth could n't lift Ryder Cup stalwart Lee Westwood to victory , either . He was only a shot behind overnight leader Alejandro Canizares . Westwood , who recently moved his family from England to Florida , led at one stage on the front nine but was undone by a double bogey and two bogeys on the back nine . He finished the fourth round at one-over 73 . He was bidding to better two runner-up finishes at Wentworth . `` Obviously Lee had the most support at the beginning , but I had so much -- the crowd in general this week has been unbelievable , really , '' Manassero added . `` I think the weekend that they got to see was a reward for the people that were here Friday with that weather to watch . '' Manassero and Warren had chances to win the title before the playoff but faltered . Khan , five shots off the pace going into the final round , made a charge with a 66 . When Khan won the PGA Championship in 2010 , he rallied from a seven shot deficit in the final round with another 66 . He was playing his first event since March due to his wife 's illness , the European Tour 's Web site reported . `` I wanted to prove to myself I 've got it in me and that 's been the great thing today , '' Khan was quoted as saying . `` I 've played great . After such a long layoff , to come back and lose in a playoff of this fantastic tournament , I can take a lot out of it definitely . `` I felt great going into the playoff . It 's just a shame that second shot ( on the fourth extra hole ) did n't carry another couple of yards or I would probably be going back out to 18 again . '' Canizares and Miguel Angel Jimenez , the oldest man in the tournament at 49 , finished a shot off the pace . British Open champion Ernie Els tied for sixth following a final round 67 , while Sergio Garcia , under fire last week for `` fried chicken '' jibe , ended up tied for 19th .
