Justin Rose shot a flawless 66 to beat Lee Westwood by a shot and capture the $1.5m first prize cheque at the Turkish Airlines World Golf Final.
Rose had beaten his Ryder Cup team-mate in the group phase of the eight-man tournament and was never headed in the final after sinking a 20 foot birdie up at the opening hole to go one in front.
In a match of high quality, neither player had a single bogey on his card but Westwood's inability to hole a string of good birdie chances eventually cost him.
After both had birdied the par three fifth, Westwood caught Rose at the seventh hole after a two-putt birdie.
But at the par three eighth, Rose plonked his tee-shot to eight feet and calmly rolled in his birdie putt. It put him one in front again and it was a lead he never relinquished.
Still one up at the turn, Rose doubled his lead with a fourth birdie of the day at 10 after a wedge to 10 feet.
Westwood, who carded a brilliant 61 to win his semi-final, couldn't find the same spark and a string of wasted opportunities was highlighted by a missed putt from inside three feet at the 13th.
Rose missed from similar length at 16 where Westwood birdied to cut the gap to one again but Rose effectively slammed the door by sinking a 20 footer for birdie at 17.
Westwood made one last push at 18 by holing out for birdie after a towering approach to five feet but Rose held his nerve to hole out from three feet and take victory by a shot.
Burned the edge
A delighted Rose admitted that Westwood missed plenty of opportunities in their 18-hole final.
He said: "Lee again played solidly today. Where the putts went in yesterday for him, they burned the edge today and when he'll look back at the round there were a lot of chances for him.
"But it got tight at the end. He did what he had to do; he put the pressure on me all the way. He made a great four at 16 where I thought his ball was actually wet with the second shot.
"And then obviously at the 18th he kept the pressure going."
As for what he might do with the $1.5m winner's cheque, Rose laughed: "What's my wife going to do with it, let's put it that way.
"It's a lot of money, we're very fortunate. I'm spoilt for choice."
Westwood shouldn't feel to deflated either. His second prize was a cheque for $1m.
