Rory McIlroy has little interest in following Jason Day's example and teaming up with a so-called superstar caddie, the four-time major winner said in the wake of Day's decision to hire the sport's best known bagman.
Day coaxed Steve Williams out of retirement starting at the recent US Open, saying he thought the veteran caddie's experience would be an asset as he tried to play his way back to world number one status.
Williams caddied for Tiger Woods in 13 of the American's 15 major victories.
Day's decision to hire Williams raised the question of whether other top players might follow suit, perhaps trying to lure someone such as Jim 'Bones' Mackay, who worked for Phil Mickelson for 25 years.
McIlroy has been using his lifelong friend Harry Diamond for nearly two years now, with the former world number one saying that he no longer needed an old hand on the bag.
"Maybe back in the day when I wasn't as experienced, but I've been on tour for 12 years," McIlroy said.
"Caddies don't hit the shots. I want someone out there I'm comfortable with. That's the big thing for me and that’s why I have Harry on the bag."
Diamond is expected to work for McIlroy at next week's Scottish Open and the following week's The Open at Royal Portrush, where McIlroy shattered the course record with an 11-under-par 61 in the 2005 North of Ireland Amateur Championship.
McIlroy will miss this this week's Irish Open after being the tournament host from 2015-2018.
McIlroy, 30, has not tasted victory in one of golf's four biggest championships since 2014.
His previous caddie JP Fitzgerald was on the bag at all four of McIlroy's major victories between 2011-14.
But McIlroy said Diamond, who represented Ireland as an amateur, brought an extra asset to the job.
"Having someone by your side that actually knows the game and knows how to play the game, and can sort of see different shots, and have a feeling of what way a ball's going to come out of a certain lie in the rough, all of that stuff (is an asset)," he said of Diamond,
"Harry’s my best friend. We were best man at both of our weddings. I'm comfortable out there with him and feel like he does a better job.
"I don't envision a day where I go to a superstar caddie, or a well-known caddie. I just don’t think it's in my approach."
