Rory McIlroy has admitted his new role off the course in thwarting the threat of the PGA Tour 's newfound rivals LIV Golf, is beginning to take its toll.
The PGA Tour has been at war with LIV Golf for the past 10 months, after the Saudi-funded series emerged as a direct threat to the Tour's position at the top of professional golf. One man who has been key to the American-based circuit's staunch defence is McIlroy.
The four-time major champion has emerged as one of the breakaway circuit's biggest critics, often taking aim at LIV's controversial chief executive Greg Norman.
