Jordan Spieth is one of the most entertaining players to watch on the PGA Tour and a large part of that comes down to his relationship with his caddie, Michael Greller.

Michael Greller and Jordan Spieth feature prominently in the first season of the popular Netflix golf docu-series, Full Swing, and the man who carries Spieth’s bag is one of the most popular on the PGA Tour.

Greller has been on the bag of Spieth since 2011, and in that time, the pair have won three major championships.

Before getting under the strap for Spieth, Greller was a middle school maths teacher, and worked part-time as a caddie to earn extra cash. He initially took on working for Spieth as a temporary job, expecting to go back to teaching. However, that all changed when Spieth won the 2013 John Deere Classic, his first PGA Tour win.

Since then, Greller has remained on Spieth’s bag, and the pair have become one of the most entertaining duos in the game.

Who is Michael Greller?

Born in Michigan in 1978, Michael Greller graduated from George Fox’s university in 2003 as a Master of Arts in Teaching, and worked as a middle school maths teacher. He was preparing to take a year-long break from teaching in 2012, when Jordan Spieth’s father, Shawn Spieth, reached out to him to ask if he would caddie full-time for his son.

Greller is married to Ellie, and it was her that encouraged Greller to take on the opportunity to caddie for Jordan Spieth.

“I had an incredible teaching job but was ready to try something different,” Greller explained to George Fox University.

“My wife Ellie encouraged me to go for it. We were watching the Masters when she said, ‘If Jordan is winning the Masters in ten years, are you going to be asking yourself why you didn’t pursue it?’ She’s right. I would have been kicking myself.”

Greller is the son of John Greller and Jane Greller. Spieth’s father, Shawn, took over on caddying duties in 2019, when Greller’s father passed away. His mother, Jane, passed away the following year. Greller has two siblings, Tom Greller and Katie Greller.

On the golf course, Greller is well regarded as one of the best caddies on tour. He is often seen engaging in conversations with Spieth, where the pair don’t always agree at first. However, more often than not, Greller will get Spieth to hit the right shot, despite his player not always agreeing.

This was evident at the Genesis Scottish Open in 2022, where Spieth was skeptical as to whether his shot was going to get anywhere near the green on the par-3 6th hole.

Jordan Spieth is still currently chasing the career grand slam with Michael Greller, in what is one of the most compelling player-caddie relationships on tour.
