It was only nature to seek player reaction to the allegations made about Phil Mickelson and his gambling habits by his former associate Billy Walters in his upcoming autobiography when they were revealed in an excerpt published by Fire Pit Collective and Golf Digest on Thursday.

Walters says in the book that he and Mickelson became gambling partners and that Lefty wagered more than $1 billion over three decades while losing nearly $100 million in that time. Walters also detailed a time when he says Mickelson asked him to place a $400,000 wager on the U.S. winning the 2012 Ryder Cup, a team Mickelson was playing on. Walters said wouldn’t go ahead with the bet out concern over what it might do to Mickelson’s reputation if it ever became public. Mickelson, after the story was reveal, denied ever placing a bet on the Ryder Cup.

On Thursday after the opening round of the FedEx St. Jude Championship, Rory McIlroy had fun at Phil expense with a response to the follow question:

  1. The talk of the golf world is this book excerpt that came out about Phil Mickelson. I’m curious what your reaction, what the reaction in there was when you read about it.

RORY McILROY: At least he can bet on the Ryder Cup this year because he won’t be a part of it.

Jordan Spieth also looked like he was ready to either provide a thoughtful response to him impression of the story, or potentially a humorous quip like McIlroy. But then, suddenly, in mid-sentence it was as if he completely changed his mind about getting into the whole matter at all.

“I mean, I would say people were maybe a bit surprised at the amount of … I haven’t really seen a whole lot on it. I just saw what some people sent me and stuff, and it was so quick this morning that even if I wanted to comment, I don’t think it’s a good idea,” Spieth said.
