Why he’s on the list: The U.S. Open showed that McIlroy is capable of complete domination. The rest of the field could do little more than watch as he won by eight strokes and broke the U.S. Open record by four strokes. If the results portend those in years to come, Rory McIlroy will become a household name. At just 22, there’s plenty of time for that. To boot, his well-publicized relationship with tennis phenom Caroline Wozniacki could double-down the sponsorship opportunities for the superstar duo.
