Rory McIlroy has long been held in high regard, having earned rave reviews in the junior ranks, and he has transferred that to the highest level by winning his first major at the age of 22.

Prior to turning pro in 2007, McIlroy won a string of tournaments on the amateur circuit and helped Europe's team win the 2004 Junior Ryder Cup.

Hardened golf fans were aware of his talents through the early part of the previous decade, but he burst on to the scene when winning the Silver Medal for the top amateur at the 2007 Open Championship - having posted the only bogey-free round in the first round at Carnoustie.

McIlroy turned pro shortly afterwards and finished third in his second professional event, the Alfred Dunhill Links Championship. The young Ulsterman made steady progress in 2008, breaking into the world top 100, and a play-off defeat at the UBS Hong Kong Open at the start of 2009 propelled him into the top 50.

McIlroy's debut victory on tour came in the 2009 Dubai Desert Classic, when he showed nerves of steel to hold off Justin Rose by a single shot.

He had a fine end to 2009 and was pipped to the Race To Dubai by Lee Westwood, but he did become only the second 20-year-old, the other being Sergio Garcia, to break into the world's top 10.

His form in 2010 was solid, he recorded his first win on the PGA Tour at the Quail Hollow Championship, but he failed to turn a string of promising positions into regular wins.

He made his Ryder Cup debut in the success in 2010 at Celtic Manor and after taking the decision to hand back his PGA Tour card, he will look to press ahead in 2011.

McIlroy's record in the majors is excellent, securing top three finishes in The Open and US PGA Championship.

He suffered meltdown when leading after three rounds of The Masters in April 2011 only to shoot 80 in his final round - but he put those woes behind him by storming to a stunning victory in the US Open at Congressional.

Career high: McIlroy proved he can cut it at the highest level by leading from start to finish to win the US Open by eight shots.

Career low: Suffered total meltdown in the 2011 Masters. He produced imperious golf for three rounds to take a four-shot lead into the final 18 holes. He led by one at the turn, before a triple bogey seven on the 10th set him on a slippery slope towards an 80 and a share of 15th place.

Quote: "I expect a lot of myself. I put myself under the most pressure, because I want to do well. I don't really let what people say affect my game. As long as I can live up to my own expectations, I am doing okay."

Trivia: Is the second 20-year-old to break into the world's top ten, after Sergio Garcia.
