Riv not LIV is the mantra this week at the Genesis Invitational.

LIV Golf is the upstart circuit led by Greg Norman and financially supported by Saudi Arabia’s Public Investment Fund. Its first tournament of 2023 will be at the El Camaleón Golf Course in Mayakoba, Mexico, next week and its golfers include last year’s Genesis winner, Joaquin Niemann.

Riv is a favored diminutive for Riviera Country Club, the venerable Pacific Palisades par-71 layout playing host to this week’s PGA Tour event that will include every golfer in the top 25 except Niemann and Cameron Smith, another LIV defector.

It also will include Tiger Woods, a surprise entry. Woods is a staunch PGA Tour supporter who has worked with Rory McIlroy and others for a year to combat LIV.

"It's been very turbulent. ... It's been difficult, there's no lie," Woods said. "We never would have expected the game of golf to be in this situation, but it is, that's the reality.
