Rory Mcilroy, 23, Northern Ireland
Quick, name a golfer. Okay, not Tiger Woods. Okay, not Phil Mickleson. Chances are you probably came up with young Irish scrapper, Rory Mcilroy. The 23-year-old phenom is the heir to the Nike throne that won the PGA Championship and U.S. Open. The last time a youth had taken home those major championships were, you guessed it, young Eldrick.
