Phil Mickelson Phil Mickelson

It’s not exactly a secret that golf superstar Phil Mickelson is a prolific gambler, but the true extent of his gambling habit is probably more mindblowing than anybody previously realized.

In his new book, Gambler: Secrets from a Life at Risk” prolific sports gambler Billy Walters detailed a relationship and partnership with Phil Mickelson and also revealed some absolutely insane facts about Mickelson’s gambling habits, claiming that Mickelson has lost close to $100 million gambling and wagered a total of more than $1 billion.

Here’s an excerpt from his book, via Golf Digest:

After my betting partnership with Phil ended in the spring of 2014, I learned a lot more about his sports gambling from two very reliable sources.

They said it was nothing for Phil to bet $20,000 a game on long-shot, five-team NBA parlays. Or wager $100,000 or $200,000 a game on football, basketball, and baseball. Based upon my detailed betting records and additional records provided by the sources, here is a snapshot of Phil’s gambling habit between 2010 and 2014:

• He bet $110,000 to win $100,000 a total of 1,115 times.

• On 858 occasions, he bet $220,000 to win $200,000. (The sum of those 1,973 gross wagers came to more than $311 million.)

• In 2011 alone, he made 3,154 bets—an average of nearly nine per day.

• On one day in 2011 (June 22), he made forty-three bets on major-league baseball games, resulting in $143,500 in losses.

• He made a staggering 7,065 wagers on football, basketball, and baseball.

Based on our relationship and what I’ve since learned from others, Phil’s gambling losses approached not $40 million as has been previously reported, but much closer to $100 million. In all, he wagered a total of more than $1 billion during the past three decades.

Obviously, this led to a lot of reactions on social media.

It’s clear that Mickelson has quite the gambling habit.
