Justin Thomas has set the world of golf alight since gaining his PGA Tour card in 2015, winning every season he has been on tour, including the US PGA Championship in 2017.
Throughout it all, he has had the same man on his bag: Jimmy Johnson.
Johnson had previously been the regular caddie for American Steve Stricker, before the American had to reduce his playing schedule due to his back surgery.
In 2015, Stricker gave Johnson his blessing to start working for young up-and-comer Thomas.

He has also caddied for other big names in the game such as, Charles Howell III, Nick Price and Adam Scott.
Despite the 36-year age difference between the pair, Thomas and Johnson are a formidable partnership.
“Because I’m older than him, I didn’t want to come across like a know-it all,” Johnson told the Caddie Network. “I wanted to be more of a big brother than a father figure. He has a father.
“Justin trusts me. I’ll let him do something if he thinks he can do it. We will talk through it. We have a total understanding with each other.”
Thomas added: “There aren’t really any situations he hasn’t been in before and, to me, that's great because he is going to know the right things to say to me.

“He’s also such an even-keel person that he’s always keeping me relaxed, too. We just got along.”
Like many caddies, Johnson is more than capable of swinging a golf club himself and plied his trade for 17 years on the Sunshine Tour in South Africa.
