(CNN) -- Scotland's Martin Laird beat George McNeill and Chad Campbell in a three-way playoff to claim his maiden PGA Tour win at the Las Vegas Open.
Laird claimed the biggest triumph of his fledging career in Las Vegas.
The trio finished four rounds at the TPC Summerlin on 19-under 265 with Laird shooting a three-under closing round of 68.
Campbell was the first out of the playoff as he missed a short par putt on the 17th.
At the third extra hole, McNeill made a hash of his approach to the par-four 18th and ran up a bogey, leaving the 26-year-old Laird to two-putt from 11 feet to secure a dream victory.
Laird, who has forsaken the European Tour to campaign in the United States, claimed he had been unfazed in the playoff, despite the enormous pressure.
"The most nervous I was was the first few holes starting out, and then coming in there I was amazed how calm I was coming down the stretch," he told reporters.
The victory in a tournament which had pop star Justin Timberlake as host earned him £750,000 and a two-yeaer exemption on the PGA Tour.
"I had two great shots on 17, and I was determined not to let a good swing cost me the tournament on bogey, and obviously making the putt on 18 was big," he added.
American pair Campbell and McNeill had to settle for a share of second place while three-time Las Vegas winner Jim Furyk slipped to a two-over 73 to miss the playoff by a shot.
He tied for fourth with Jeff Klauk on 18 under.
Charley Hoffman was next on 17 under after four steady rounds while Rickie Fowler, playing in his first PGA Tour event, was in a group of seven players tied on 16 under.
