After his winning his first major overnight at the US Open, Northern Ireland's Rory McIlroy is intent on claiming many more in a career that has only just begun.

The 22-year-old led from start to finish at Congressional to become the youngest major champion since Tiger Woods won the Masters in 1997.

"To get my first major out of the way quite early on in my career, especially after what's happened the last couple of months, feels great," he said.

"Now, I'm looking forward to putting myself in the picture for many more."

The new world number four produced rounds of 65, 66, 68 and 69 for a tournament record, 16-under-par total of 268, four better than the previous mark.

McIlroy had previously only won one US Tour title and one European Tour title, but showed his talent in majors by finishing tied for third in last year's British Open and US PGA Championship.

He was poised to make the Masters his first major title when he held a four-shot lead going into the final day earlier this year, but a meltdown on the 10th hole led to a triple-bogey and he ultimately carded a final-round 80.

There would be no collapse at Congressional, though. With an eight-shot lead going into the final round, McIlroy showed few signs of nerves and stretched his lead to 10 shots with two birdies in the opening four holes.

He made only his second bogey of the week after driving into sand on the 12th, but kept up the momentum with a number of crucial putts on the back nine.

His first three-putt of the week at the 17th saw him drop a shot but he held his nerve for par at the last to banish his Augusta demons and win his first major title by eight strokes – the fourth highest winning margin in US Open history.
