Justin Rose claimed his first win on the US PGA Tour in 2011 by hanging on for victory at the BMW Championship in Illinois.
The 31 year old started the final round with a four shot lead but had to endure some nervous moments before edging out John Senden by two strokes.
Rose started his round nervously with a bogey at the par three second, but birdies on the sixth and seventh got him back on track.
Another bogey followed on the ninth and he was fortunate to escape with a six on the par five 15th after a wayward tee-shot which flew into the trees.
He held a one shot advantage over Senden going up the 17th but, after a poor approach, a wonderful holed chip for birdie effectively handed him the title, with Senden only managing a par after putting his second shot in the bunker.
"I had my ups and downs and the learning curve is steep sometimes," Rose said. "It was hard today, I took on a couple of crazy shots and had to have a quiet word with myself."
As for the chip on the 17th, he added: "I nearly took the chicken stick out and putted it but I said to myself it was a makeable chip so I had to commit."
Senden was the model of consistency with birdies on the ninth and 10th his only deviation from par.
The Australian finished a shot ahead of countryman Geoff Ogilvy, who carded a closing 69.
Luke Donald ended another impressive week by coming fourth courtesy of a 68 today which contained three birdies on the back nine.
Webb Simpson finished fifth, a shot ahead of Camilo Villegas and Jason Dufner.
