I just read this on theScore:
The likes of Rory McIlroy, Justin Thomas, Scottie Scheffler, and Sam Burns are battling at the Canadian Open for the $1.55-million payout to the winner. The 19th-place finisher at St. George's in Toronto will pull in just over $123,000. In London, Andy Ogletree shot rounds of 82, 77, and 75 to finish an outrageous 31 shots behind Schwartzel for the event. He'll still take home $120,000 for his work.
The significant six-figure deal Johnson got to jump ship to LIV Golf has been well-documented, and the two-time major champion takes home $625,000 for his eighth-place finish in London. That's just $373,000 less than he's made on the PGA TOUR all season.
If these payouts are sustainable then I don't see how the PGA can compete if you're making 2/3rds of your annual earnings in one week. Plus that massive signing bonus.
