KUALA LUMPUR (AFP) - Italian teen sensation Matteo Manassero won the Malaysian Open by one shot from Frenchman Gregory Bourdy on Sunday to seal his second European Tour victory. Manassero, who turns 18 on Tuesday, shot a fourth round four-under-par 68 at the Kuala Lumpur Golf and Country Club to seal the win with a four-round total of 272. There was no comeback for world number nine Rory McIlroy a week on from his last-round collapse at the US Masters. The Northern Irishman battled bravely on the back nine to give himself a shot at victory but a bogey on the last meant there was no playoff with Manassero as McIlroy finished third on 14-under 274. Bourdy posted 67 for a 273 total, while US PGA champion and world number one Martin Kaymer was eight shots back in a tie for ninth and Masters winner Charl Schwartzel a stroke behind in 11th. The young star said an eagle on the par-five 10th had set him on his victory charge and subsequent birdies on 11 and 14 helped seal the hard-fought win over Bourdy. Manassero received the winner's cheque of $416,660 and became the Malaysian Open's youngest winner and the first Italian to win the tournament. He put his flawless play down to his ability to keep a cool head despite coming under pressure from other players and the uncertain weather. "All the players were doing well. It is not easy to concentrate and stay calm. Fortunately I stayed calm," he said. Manassero became the youngest ever winner on the European Tour when he took the Castello Masters in Spain last year and Sunday's triumph means he is the third youngest on the major world tours to record more than one victory. The win also propels Manassero into the top 35 in the world rankings and he said his success in golf was due to the upbringing by his parents who patiently allowed him to develop his talent. McIlroy, 21, came into the tournament off the back of a gruelling journey from Augusta and said he was pleased with his performance despite the disappointing result. "To shoot the scores that I did considering the travelling is a pretty good effort. I'm disappointed with the result but everything else was positive," he said. "I'm proud at how I picked myself up from last week and the way I came back on the back nine today."
