In his first interview since suspending 17 players for competing in the rival LIV Golf Invitational Series, PGA Tour commissioner Jay Monahan defended the punishment in an interview with CBS Sports during the final round of the RBC Canadian Open on Sunday.

Six-time major champion Phil Mickelson, two-time major winner Dustin Johnson and longtime PGA Tour members Sergio Garcia, Lee Westwood, Louis Oosthuizen and Kevin Na are among those who are now ineligible to compete in tour events after playing in the inaugural LIV Golf tournament in London this past week.

“It’s been an unfortunate week that was created by some unfortunate decisions, those decisions being players choosing to violate our tournament regulations,” Monahan said. “It’s my job to protect, defend and celebrate our loyal PGA Tour members, our partners and our fans. And that’s exactly what I did. And I don’t think it was a surprise to anybody, given how clear I had been about how we were going to handle this situation.”

Rory McIlroy, who won the Canadian Open by 2 shots over Tony Finau, couldn’t help but take a subtle jab at LIV Golf CEO Greg Norman in a news conference on Sunday.

It was McIlroy’s 21st PGA Tour victory. “And one more than Norman,” McIlroy told a moderator.

“I think going up against the best and beating the best always makes it extra special,” McIlroy said. “And then, look, I alluded to it, I had extra motivation of what’s going on across the pond. The guy that’s spearheading that tour has 20 wins on the PGA Tour and I was tied with him, and I wanted to get one ahead of him. And I did. So that was really cool for me, just a little sense of pride on that one.”

The next LIV Golf tournament will be played in the United States, at Pumpkin Ridge Golf Club in Portland, Oregon, from June 30 to July 2. LIV Golf announced over the weekend that it added former U.S. Open champion Bryson DeChambeau, former Masters winner Patrick Reed and Pat Perez to its roster. They are scheduled to compete in Portland.

Monahan said players who compete in future LIV Golf events will face the same punishment as the 17 players who were suspended last week.

When Monahan was asked why players couldn’t compete on both the PGA Tour and LIV Golf circuit, he didn’t back down from his previous position that players had to choose one tour or the other.

“Why do they need us so badly?” Monahan said. “Because those players have chosen to sign multiyear lucrative contracts to play in a series of exhibition matches against the same players over and over again. You look at that versus what we see here today and that’s why they need us so badly. You’ve got true, pure competition. The best players in the world are here at the RBC Canadian Open, with millions of fans watching, and in this game, it’s true and pure competition that creates the profile in the presence of the world’s greatest players.

“And that’s why they need us. That’s what we do. But we’re not going to allow players to free ride off of our loyal members, the best players in the world.”

Monahan also was asked about players being criticized for competing in a circuit that is financed by Saudi Arabia’s Public Investment Fund. Survivors and family members of victims of the terrorist attacks of Sept. 11, 2001, have been critical of players downplaying the Saudi Arabian monarchy’s history of civil rights violations.

“It probably is an issue for players that chose to go and take that money,” Monahan said. “And I think you have to ask yourself the question, why is this group spending so much money, billions of dollars, recruiting players and chasing a concept with no possibility of a return? At the same time, there’s been a lot of questions, a lot of comments about growth of the game. And I asked, how is this good for the game that we love?

“I talked to players. I’ve had a player meeting, and I’ve talked to a number of players individually for a long period of time. And I think you’d have to be living under a rock to not know that there are significant implications. And I would ask any player that has left or any player that would consider leaving, have you ever had to apologize for being a member of the PGA Tour?”
