While the U.S. Amateur proved a good fit for Riviera given the weather and sensational match play setup by the USGA's Ben Kimball, it was not a big draw in LA. The miniscule crowds, even more miniscule member support and commitment to the possible 2028 Olympic golf all but rules out any return to the major championship world. The U.S. Open is also slated to return to Los Angeles in 2023 at The Los Angeles Country Club.
Apparently in the mind of the club's "corporate officer" Michael Yamaki, the amateur has positioned Riviera for the first ever boutique Ryder Cup. His reasoning? Folks in LA overpay for Laker courtside seats and gasoline at San Vicente and Allenford, so they'll do the same at Riviera for a massive-scale golf event like the Ryder Cup, PGA or U.S. Open.
From John Strege's Golf World item:
“I’m still talking with the PGA of America. At some point they professed they’d like to see a Ryder Cup on the West Coast. I think we could do that event. I’d still like the PGA Tour [to consider] a Presidents Cup here.”
And this pearl...
“Its [the USGA] perception of us here in Southern California is that we’re just in our hot tubs or surfing,” Yamaki said. “They don’t think that we will support sports in the same way as the East Coast.”
Given the piles of tickets from the U.S. Amateur, I'm guessing the USGA's mind hasn't been changed.
