Northern Ireland's Tom McKibbin has spurned the advice of mentor Rory McIlroy and is giving up a PGA Tour card to join Saudi-backed LIV Golf.

The four-time major champion has a lot of thoughts on the state of pro golf but said “we shouldn’t try to dumb down golf to appeal to more people.”

McIlroy makes his season debut on the U.S.-based circuit this week at the AT&T Pebble Beach Pro-Am, one of the tour’s $20 million signature events. It’s a big week—or at least it’s supposed to be, with a limited field of 80 players that includes 45 of the top 50 in the world playing one of the most iconic courses on the planet.
