Phil Mickelson: Gambling crossed the line ‘into addiction’

Less than a month after the release of a book that detailed his gambling ventures, Phil Mickelson announced Monday that he will refrain from wagering on football games this season after he struggled with a betting addiction.

The book, written by famous Las Vegas gambler Billy Walters, came out on Aug. 23 and revealed that Mickelson lost nearly $100 million due to betting. It also made note of a five-year gambling partnership between Walters and Mickelson.

Walters accused Mickelson of trying to bet on the 2012 Ryder Cup, but Mickelson denied those claims, telling Golf Digest that he “would never undermine the integrity of the game.”
