Phil Mickelson is a legend in his own right, and if you’re even remotely familiar with golf, his name should ring a bell. With more than 45 event wins and six major championships to his name, he’s cemented his place among the most talented athletes in the sport’s history.
Yet behind the calm, confident exterior lies a story of loss and addiction that shadowed Mickelson for more than three decades. Over that time, he wagered more than $1 billion and reportedly lost around $100 million to gambling.
You may know Mickelson as the unflinching golfer who can sink a putt from almost any situation — but you probably don’t know Mickelson the gambler. This is his story.
