Both players came to the par-five closing hole knotted at 20-under. Neither Scott nor Rose could reach the green in two shots, as both found rough in front of the green. Rose, playing his second from a bunker, chipped on to the green and watched as his ball rolled eight feet past the cup. Scott landed his third shot four feet short of the cup.
Rose's birdie putt slid by left, opening the door for Scott to claim his first professional title. Scott confidently ran the putt home to set the new tournament record, which was previously 269 set by Nick Price and David Frost in 1997.
'I've led a few tournaments and haven't sealed it, so it was nice to do that this time,' said Scott, who was in constant contact with his new coach Butch Harmon all week. 'Butch told me before the round not to go out there and try and win the tournament, but just to play a round of golf. That helped me to focus on what I had to do.'
At the beginning of Sunday's final round, Scott held a one-shot edge over Rose and Dean Robertson. Scott started with birdies on two, three and five to extend the lead. Rose did not fair as well as Scott as he bogeyed the first hole.
Scott's lead was trimmed after he three-putted both the ninth and 10th greens, giving him back-to-back bogeys. Rose had erased his early miscue with birdies at five and nine.
The 13th proved to be a critical hole. Scott's approach shot at the par-four hit the flag and bounced back off the front of the green. He could not get up and down and had to settle for bogey. Rose drained a 20-foot birdie to suddenly find himself at the top of the leaderboard.
Scott rebounded from the bogey at 13 when he holed a tricky birdie putt at 14, tying the two for the lead. Both players were able to birdie the 523-yard 16th, setting up the duel at 18.
This is Scott's first career victory since turning professional in June of last year. He won in only his ninth start on the European Tour.
Rose finished alone in second after a three-under 69, but had to wait for official confirmation. A rules official spotted what he thought was rules infraction by Rose at 18. The official seemed to think that Rose tested the condition of the hazard, a rules infraction.
The official did not penalize Rose after he was convinced that the movement was nothing more than a nervous twitch.
'I'm proud of the way I performed,' stated Rose, who has struggled on tour since turning professional after finishing fourth at the 1998 British Open. 'I hung in there and felt comfortable down the stretch. I feel more confident now.'
Robertson posted a two-under 70 on Sunday, tying him for third at 19-under with Nick Faldo. The six-time major winner carded a four-under 68 on Sunday.
Defending champion Anthony Wall came in fifth at minus-18.
Malcolm MacKenzie took sixth at 17-under 271, while Brian Davis and Retief Goosen shared seventh, one-shot behind MacKenzie.
