Scott's game was in a rut when he received a captain's pick from his idol Greg Norman for the International Team in 2009, the Australian having missed the cut in three of the year's four majors.
And although the United States won by five points in San Francisco and Scott claimed just one win, the 32-year-old received a major confidence boost from Norman and team-mate Angel Cabrera - the man he beat in Sunday's play-off at Augusta.
"Angel is a great man and I've gotten to know him a fair bit through Presidents Cups," explained Scott, who won his first major and became the first Australian victor at Augusta with a birdie on the second play-off hole.
"I played with him a couple of times in them and have spent some time with him, and he said a great thing to me in 2009. I was on a captain's pick there and my form was struggling, but he pulled me aside and he said, 'You're a great, great player.'
"It's something I didn't forget and was really nice of him.
"That Presidents Cup was a big moment for me. It was kind of gut-check time. My game was in a bit of a rut and I wasn't enjoying it so much. But Greg as the captain had a lot of faith in me and belief that I could win a point for his team. He gave me a pick and I didn't want to disappoint him.
"To think back to it, what that did was automatically put me into a world-class situation of playing. There's no hiding in a Presidents Cup. You have to go out there and you're playing against the best players in the world, and I used that as a real motivator and also a way to make myself believe that I'm a great player again.
"If you don't have that opportunity, sometimes it's very hard to play yourself out of a rut back up to the top of the leaderboard in a tournament. But I got put in that situation of pressure all over again and I needed that.
"I took the ball from there and ran with it. It was a big boost for me and then shortly after that, I was playing well again."
It still took Scott until Sunday night to turn that good play into a major title, with his most famous near-miss coming in the Open at Royal Lytham last year when he led by four with four holes to play, bogeyed them all and lost to a last-hole birdie from Ernie Els.
At the time Scott insisted he would take the positives from his play over the first 68 holes at Lytham, and speaking after slipping on the Green Jacket on Sunday night, he added: "Everything I said after the Open is how I felt and I meant it.
"It did give me more belief that I could win a major. It proved to me, in fact, that I could."
