Nike insisted it would remain in the apparel business, and after the signing of Jason Day, the world No 3, in February, this was further emphatic proof. The company released a short statement in which McIlroy said: "I've loved this company since I was a kid. I'm really happy to continue this journey with Nike."
The 27-year-old, who has been named by Golf Digest as the highest-earning figure in golf, with an annual off-course income of $32 million, would watch his worth soar if he won the Masters this week and became only the sixth player in history to complete the grand slam.
However, the money would mean little compared to the honour of donning the green jacket, a moment of which he has always dreamed. McIlroy is marrying his fiancée, Erica Stoll, in the weeks after the season's first major, but he feels he requires a Masters title if he is to be completely "fulfilled".
"I'd love to give you an answer and say my life is already fulfilled, with everything that's happened, and everything that's going to happen in the future, by starting a family and all that," McIlroy told ESPN. "But if I didn't have a green jacket, there'd be a tiny piece that would just be missing. It really would be. And yeah, I'd be lying if I said, as a person... I wouldn't be fulfilled if I didn't get it.
"I said when I was eight years old that I wanted to be the best golfer in the world and I wanted to win all the majors. I've nearly done all of that. There's one piece of the puzzle that's missing."
