(CNN) -- World No.1 Rory McIlroy has ended months of speculation by confirming a sponsorship deal with Nike that could net him between $200-250 million according to media reports.
The two-time major winner from Northern Ireland joins Tiger Woods at the sports giant, who now have arguably the two biggest names in golf on their books.
At a press conference in Abu Dhabi, where McIlroy will this week play in the HSBC Golf Championship, Nike confirmed their new "multi-year" arrangement with golf's rising superstar but refused to reveal any extra details.
McIlroy told gathered reporters: "I've always associated Nike with the best. I play for titles I don't play for money."
McIlroy is out on his own at the top of the world rankings and the 23-year-old has shown he is capable of emulating Woods' haul of 14 majors.
It is a major coup for Nike after they recently dropped cyclist Lance Armstrong, who has been stripped of his seven Tour de France titles for doping offenses.
McIlroy was introduced as a Nike staff player by Cindy Davis, president of Nike Golf, who said the deal signified a "significant moment for our brand and our golf business, and for the career of an extraordinary young athlete."
At a stroke, the deal transforms McIlroy into one of the hottest commercial properties in sport.
According to the Forbes list of 2012, McIlroy's deal with Nike will make him the highest paid young sports star in the world, taking him well above the $17.4 million he earned in the year up to July 2012.
Yet he still has some way to go to catch Woods, who raked in total earnings of $59.4 million in the same time period.
Nonetheless, both trail behind the world's top two highest grossing sports stars, boxers Floyd Mayweather Jnr and Manny Pacquiao, who earned $85m and $62m respectively according to Forbes.
Last year, McIlroy won his second major -- adding the PGA Championship to the U.S. Open title he won the year before -- while also becoming world No. 1 for the first time.
"Last year was a big year," he told the audience in Abu Dhabi. "This year, I think I can go to a new level. I'm practicing as hard as ever, with the best company behind me, and hopefully I can win more majors."
"Growing up I always thought all the best athletes in most sports were Nike players and I'm looking forward to joining the Nike family," he added.
McIlroy started testing his new clubs at the Nike factory in Texas late last year and says the transition from his former Titleist equipment has been seamless.
"I was blown away by the research and development that went in, and I'm really excited about the equipment. I'm really confident in the equipment and excited to put it in play this week."
Born in the town of Holywood in 1989, McIlroy was initially taught golf by his father before turning professional in 2007.
Despite his tender age, he believes he has raised his game to a level whereby he would now consider a year without a major triumph as a major failure.
"I guess if I go this year without a major, it will be a bad year," he said. "If I get to the end of 2013 and I haven't won a major, I would be disappointed."
The latest addition to the Nike stable was welcomed in a pre-recorded video by three of the highest-profile sportsmen in the world: England and Manchester United footballer Wayne Rooney, Swiss tennis player Roger Federer and Woods himself.
