Phil Mickelson is a golfer so good that he won his first PGA Tour when he was still officially classed as an amateur. Playing in the richest era of the sport, he ranks behind only Tiger Woods in terms of prize money earned over the course of his career, at an estimated $87m. His style is eye catching, often described as 'risky' due to his habit of always choosing the more difficult shots. 'Lefty' still plays today, although it's been a few years since he won his last major tournament, which was the US Open in 2013.
Mickelson has an eye for recognizing a good endorsement deal, and that's where the rest of his money comes from. His partnership with Rolex has been particularly profitable, and when he was diagnosed with arthritis in 2010, he even made money by promoting the drug that was used to treat him!
