The two-time major winner, who had pledged loyalty to the PGA Tour, is among 42 golfers set to play in the first event for a series whose major shareholder is Saudi Arabia’s sovereign wealth fund.
Dustin Johnson, who in February pledged his loyalty to the U.S.-based PGA Tour, will be the top-ranked golfer in the inaugural event of a Saudi-backed rival tour next week at the Centurion Golf Club outside London. Phil Mickelson, who recently expressed some measure of support for the alternative circuit, was not among those listed in the field for the tournament.
