Tiger Woods has extra pressure on him every time he plays in a major championship.
He is still trying to chase down Jack Nicklaus, who had 18 major tournament victories in his career. Woods currently has 14, but he has been holding at that total for the last five years.
Woods is a top front-runner at the 2013 Open Championship at Muirfield, and he likes to play with the lead. He may not be out front after 18 holes, but his opening round 69 was impressive nonetheless.
