'It is an important win, every win is important but it is important for me to win in Britain and in the continent of Europe, under different conditions,' said Scott, who shattered the previous 72-hole tournament record by nine strokes. 'The other times I have won in hot weather and this week was testing, especially Friday' so I can draw a lot of confidence from that.'
More from Adam on his win.
Scott, who won the Qatar Masters in March by six strokes, was brilliant on the par-5s at the PGA Centenary Course at The Gleneagles Hotel. The Australian was 22-under on those holes throughout a commanding performance.
The 22-year-old started the day with a five-stroke lead and from the start it was evident he was not coming back to the field. Scott picked up his first birdie of the day at the par-5 second and added another at the par-3 fourth.
At the ninth, another par-5, Scott rolled in a three-foot putt for birdie to make the turn at minus-20.
Scott continued with a birdie at the 12th before a remarkable stretch over the final three holes. Scott reached the green in two at the par-5 16th and drained a long eagle putt before he ran home an 18-foot birdie at the very next hole.
Another par-5 awaited Scott at the 18th. Again he reached the green in two and converted for his fourth eagle of the tournament and an unforgettable performance. The win moved him to eighth on the money list and his 63, the best round of the tournament, was good for a Rolex.
'The reason for me to come this week was to win,' said Scott, whose 10-shot margin of victory is the largest on tour in 2002. 'To play my way back into the top 50 in the world, I need to play well because I feel like I should be up there. I haven't played well over the past few months but I've gone about it the right way, worked hard and got a fantastic result this week.'
Raymond Russell of Scotland entered the final round tied for second with Australia's Scott Gardiner. Russell started strong with back-to-back birdies before a bogey at the third. He added five more birdies to go along with an additional two bogeys to finish alone in second at 16-under-par 272.
Sam Torrance, who celebrated his 49th birthday Saturday, shot a final-round 67 to take third place at 15-under-par 273, his best finish on tour in 2002.
Gardiner found trouble with a triple bogey at the par-4 15th, but responded with two birdies over the closing three holes to finish alone in fourth at 12-under-par 276. Germany's Marcel Siem was one shot further back at 11-under-par 277 after a round of 68.
Ignacio Garrido posted a 5-under 67 to take sole possession of sixth place at 10-under-par 278. The Spaniard was followed by Ian Garbutt, Henrik Bjornstad, Andrew Oldcorn and Matthew Cort, who finished one shot further back at 9-under-par 279.
First round leader Richard Green carded an even-par 72 to finish in a group tied for 11th at 8-under-par 280. Green was joined by Raphael Jacquelin, Mathias Gronberg, Marc Warren and last year's champion, Paul Casey.
