Michael Thompson clinched his maiden PGA Tour title with a two-shot victory at the Honda Classic in Florida.
The 27-year-old from Alabama held his nerve under pressure from Geoff Ogilvy over the closing holes, sealing his success with a birdie at the last to finish on nine under par.
Having shared the lead with Luke Guthrie overnight, Thompson seized control with an eagle at the third. Although he gave one shot straight back at the next, a further birdie at the fifth pushed him three clear.
A see-saw front nine saw him finish bogey-birdie-bogey but he remained out in front thanks to six successive pars after the turn.
Although his first three-putt of the week at 16 suggested a wobble as he approached the line, Thompson would not be caught. A par at the next gave him a comfortable cushion heading down the par-five last.
"This week was magical," he said afterwards. "I had a groove, kept feeling it and kept believing. All in all, it was just a wonderful experience."
Ogilvy birdied two of his last three holes, including a wonderful chip-in at the 16th. While his efforts weren't quite enough to even get him a play-off, the Australian could console himself with the fact that he has now moved into the top 50 in the world, qualifying him for next week's World Golf Championship.
Guthrie was alone in third on five under after signing for a 73, while a fine round of 69 pushed Englishman David Lynn into a share for fourth place.
Lynn's compatriot Justin Rose (71) also finished on three under, along with American trio Keegan Bradley, Erik Compton and Lucas Glover.
Graeme McDowell ended up two under with Ryder Cup team-mate Lee Westwood for company, the latter seeing his challenge at his 'home' event in Florida disappear with a round of 74 that included five bogeys.
Tiger Woods, meanwhile, closed out his week with a 74 as well, meaning he finished up tied for 37th.
