There's a new similarity between Adam Scott and Tiger Woods.

Scott coasted to his first career PGA Tour victory on Monday, winning the inaugural Deutsche Bank Championship by four strokes.

A 23-year-old Australian whose swing is almost identical to golf's top-ranked player, Scott fired a five-under-par 66 to become the youngest winner on tour since Sergio Garcia captured last year's Mercedes Championship at 21.

Scott also joined Woods as players who claimed their first PGA wins while playing on sponsor's exemptions.

"It is kind of a relief, for one," Scott said when asked about his emotions.

"I feel that, being not just a foreigner but being a young player, there is a lot of pressure out there on this tour.

"And there are only a few young players who have done very well in the past. One is probably Sergio and the other is Tiger."

After four rounds in the 60s, Scott had a 72-hole total of 20-under 264 and claimed the £570,000 top prize, becoming the second straight member of the European Tour to win on the PGA Tour.

Northern Ireland's Darren Clarke took last week's NEC Invitational.

"Obviously, I know I can win over here, but that should not be taken for granted, either," Scott said.

"I think I have played exceptionally well this week and I made the most of it.

"As I said earlier in the week, I think I still have a lot to prove in Europe and I feel like I have a lot to achieve over there."

PGA veteran Rocco Mediate claimed sole possession of second place, and £340,000, with a six-under 65 that left him at 16-under 268.

"This is the best I have putted for a couple of years, trust me," said Mediate, whose spot in the world golf rankings has slipped to 38th.

"Everybody says your world ranking has dropped and this and that. It has dropped.

"I haven't played and the few I did play, I finished like 40th. And I spent all my time with my boys and my wife.

"My world ranking had dropped, but my ranking with my children and my wife, I'm number one."

England's Justin Rose, also playing on a sponsor's exemption, was alone in third at 15-under 269 after a final round 67.

Mediate described Scott as "as good as you can get, really."

"He hasn't even tapped (his potential)," Mediate added.

But Scott struggled with his putting, a problem that reached a "low point" at the British Open, where he missed the cut after rounds of 82 and 74.

"I took the next week off and went home and all I did was putt and chip for the week," he explained.

"I didn't hit any balls and I just spent hours putting and chipping. And that really turned it around."

The results showed on Saturday, when Scott fired a course-record 62 to grab the lead.

He made just four bogeys all week at the TPC of Boston, just one over the final 23 holes.

"I missed a few fairways and missed a few greens and I left myself some 40-footers, 50-footers, 60-footers, and I didn't really knock them stone dead," he said.

"I left them four feet, six feet, and those were the ones that surprised me, knocking them all in."

Scott made birdies at the second and third holes and his lead never dropped below three shots yesterday.

Mediate's challenge ended when he missed an eight-foot downhill birdie try at the 14th, but the 40-year-old was not disappointed by his best showing since a runner-up finish at the season-opening Mercedes Championship.

"If I had shot 62 and finished second, yeah, (I would have been disappointed)," Mediate said. "I made one little blip on 14."
