( CNN ) -- Cockiness and swagger serve him on the golf course , but there 's much more to golf 's young phenom , Rory McIlroy . The U.S. Open winner might hang with tennis great Rafael Nadal , knock back some Heinekens or slip the electronic dance sounds of Swedish House Mafia into his iPod . Such tidbits are rolling out these days from the 22-year-old hero of Holywood , Northern Ireland , who won the tournament by eight strokes and instantly drew comparisons to Tiger Woods . `` I did n't realize how much my life would change , even in the last 10 days , '' McIlroy said on `` Piers Morgan Tonight , '' aired Thursday . As Woods has done over the years , McIlroy simply left the competition in the dust . He was the youngest winner of the tournament since the legendary Bobby Jones in 1923 . For someone under a spotlight these days , the athlete with a tousle of hair looked at ease during his interview with Morgan . `` To me , I won a golf tournament and that was the end of it , '' McIlroy said . But it really is bigger than that . '' He paid tribute to his parents , who both worked when he grew up . His father , Gerry , held down three jobs and was a `` calming influence '' during the U.S. Open , said McIlroy , an only child . The U.S. Open gave the golfer a shot of redemption after his final-round meltdown at the Masters in April . `` If anything it made me more determined to prove to people and myself that I was n't ... a choker , '' McIlroy said . While saying he was inspired by Woods , McIlroy is n't one to compare himself . But he does n't feel intimidated , either . `` I do n't want to feel inferior to any other golfer in the world , '' he told Morgan . `` If you do that , you give them an advantage from the start . '' While the young McIlroy has one major championship , Woods has 14 , including three U.S. Open wins . Woods , 35 , has had no PGA wins since taking a brief leave from the game in late 2009 after admitting infidelity . Life on the tour can bring its own problems , McIlroy conceded . `` You need a good team around you to keep you grounded . '' McIlroy , who plays in the British Open next month , said he and girlfriend Holly Sweeney are a `` normal couple . '' They have two dogs and she is completing her university degree . A fan of boxing and soccer , McIlroy said he does n't want the flash of fame to affect him . After all , there are more tournaments to win . `` I 'm very confident in my own abilities . I believe in myself , '' McIlroy said . `` I 'm not playing for money . I 'm playing for a place in history . ''
