"Phil was there, and it was the day after he played Tiger" in Capital One's "The Match" — an event that was viewable by pay-per-view.
The singer-songwriter said that after he had a few drinks, he saw Mickelson and thought, "I gotta go tell this guy what I think."
"So I walked over to him, and I was like, 'Hey Phil, you owe me f------ $29.99 ... for wasting four hours of my life with the s------- golf I've ever seen,'" Owen said. "You guys hyped this whole thing up about this big match, you guys couldn't even make three birdies between the two of you.' I'm like, I want my $29.99 back and f------ apologize to me for some s----- golf."
Owen said that at that point, Mickelson pulled out a wad of cash, particularly a $100 bill. "He's like, 'Yeah, I won 90,000 of these yesterday.' He goes, 'Take $100 and go f--- yourself."
Mickelson called the encounter a "true story" in a response on Twitter.
The payout for "The Match" was $9 million.
