Jordan Spieth's caddie showed class after humiliating outburst on live TV

Jordan Spieth is widely regarded as one of the most likable men in golf, but the American could not hide his frustrations during the 2019 U.S. Open at Pebble Beach

Jordan Spieth faced criticism for lashing out at his caddie during the 119th U.S. Open - but for his caddie it's something he prefers.

Back in 2019, the then 31-year-old golfer - who has silenced his critics at this year's event - had a challenging start at Pebble Beach, standing at even par when a mishap on the eighth hole's distance measurement caused frustration. Spieth's tee shot initially landed on the fairway but kept rolling until it went over the course's cliffs and out of bounds.

Following a penalty drop due to his mistake, Spieth's third stroke overshot the green into thick rough. It was then Spieth was heard grumbling, "Two perfect shots," before venting his irritation towards caddie Michael Greller.

Spieth briskly said, not facing Greller, "Two perfect shots, Michael. You got me in the water on one and over the green on the other."

Despite a bogey at that hole and another on the following one, putting him two-over-par entering the back nine, Greller doesn't seem affected by Spieth's outward display of emotion.

Last year, Greller shared insights about working with Spieth to The Scoop, saying, "You have to be really perceptive over what your guy is thinking. For me, I am very lucky as Jordan wears his emotions on his sleeve, which is great for all of you [fans], but it's also great for me.

"I think most caddies would say you want to know what your guy is thinking. Jordan does a great job of communicating what he is thinking, no matter what it is, so it gives me a good gauge of when to back off.

"As a caddie you are always trying to protect from danger and my guy, he thinks he can pull off every golf shot in the world. It's a blessing usually and once in a while it doesn't work out, but you live for it. You would rather caddie for a guy who is fearless than scared."

Greller has been an integral figure by Spieth's side across the putting greens and lengthy fairways starting from his amateur days, with their collaboration stretching back to 2011, playing a role in each of the golfing phenom's 13 PGA Tour triumphs as well as his trio of major championships.

With a Masters, a U.S. Open, and an Open Championship already in Spieth's trophy case, there's been a noticeable gap since his last major win in 2017 at the Open. Now among the 156 competitors at Oakmont Country Club, Spieth's performance—and Greller's savvy advice—must be top-notch if he aims to break that dry spell by the tournament's conclusion on Sunday.
