(CNN) -- A stunning round of 62 that included 11 birdies propelled Charley Hoffman to the Deutsche Bank Championship Monday.
The 33-year-old American shot the best round of the tournament on its final day as he secured victory by five shots from a three-strong group that included Australians Geoff Ogilvy and Jason Day, as well as Englishman Luke Donald.
Tiger Woods finished tied for 11th -- a result that meant he hung onto his world number one ranking.
It was only Hoffman's second win in three years but victory took him to second place in the FedEx standings behind Matt Kuchar.
After his victory he told reporters: "I actually didn't know how many birdies I had. The ball just kept going in the hole, it was a really fun day
"I wasn't even close to anything for the most part starting the playoffs. Played decent last week, and just got it going this week."
Hoffman's nine-under-par round started with four birdies in the first five holes. Further birdies at the seventh, tenth and eleventh grabbed him a share of the lead before a chip-in from a bunker on 13 put him out in front.
Three more birdies cemented his win and after his round he paid tribute to short-game specialist, James Sieckmann, who he credits with transforming his skill around the greens.
"I can tell you right now -- if I wouldn't have met that guy I wouldn't have won this golf tournament," Hoffman told the PGA Tour website.
"I could barely get it out of the bunkers before, pretty shocking. He's helped tremendously with my short game and my bunker game, and I appreciate all the help he's given me and all the knowledge he has."
