Tiger Woods

Tiger Woods

    Majors won: 14 (1997, 2001, 2002 & 2005 Masters; 2000, 2002 & 2008 U.S. Open; 2000, 2005 & 2006 Open Championship; 1999, 2000, 2006 & 2007 PGA Championship)

PGA Tour victories: 79 (second all time)

Notes: It's hard to imagine that you can look at the second-winningest major champion of all time and wonder: What could have been? But, that's where we're at when it comes to Woods. He collected his 14th and final major to date at the 2008 U.S. Open. Since then, he's been plagued by health ailments that have limited his starts -- sometimes missing entire seasons. For a while there in the 2000s, it sure looked like Woods surpassing Jack Nicklaus in the major tally wasn't only a formality, but also a question of how many more he'd collect once he passed the Golden Bear. Woods changed the game, brought it to the masses and is undoubtedly the biggest reason golfers today look more like "athletes" than ever before. He's one of only five golfers to achieve a modern-day grand slam (three times) and the only player in the modern era to win four (modern-day) majors in succession -- the Tiger Slam. All the injuries are such a shame.
