Golf, Northern Ireland
Last year Rory McIlroy sounded the warning that he was Tiger Woods' heir apparent as golf's new golden boy.

He also won the PGA Tour and European Tour money titles and was voted the PGA Player of the Year and PGA Tour Player of the Year.
Lee Chong Wei's All-England wins in 2010 and 2011, had dimmed Lin Dan's aura of invincibility. But, in 2012, with the Olympics on the horizon, Lin regained the mantle by beating the Malaysian in the final in Birmingham.
And on sports' biggest stage at the Olympics, and up against arch-rival Lee again, Lin came up on top in an epic tie that cemented his place as one of the badminton's finest players.
