Phil Mickelson has earned a lot of money on the PGA Tour, but he has also lost a good deal in gambling.
According to Kaja Whitehouse of the New York Post, Mickelson lost $2 million to professional gambler Billy Walters in 2012. This equaled roughly four percent of the $48 million he earned that season.
Mickelson was accused of insider trading with Walters in 2012, but he won't face criminal charges after returning the near-$1 million he made on the deal.
The 46-year-old is one of the most recognizable players in the world with five major titles, including three Masters wins. However, he has never been shy about wagering on the course.
