It’s Saturday. You’re driving along the way, maybe going to the golf course or a college football game with family or friends.

And then, suddenly, out of nowhere, you do a huge double take. To your right is the reigning US Open champion, holding up a cardboard sign that reads, “Send this to a friend who always has 3 putts.” You won’t believe your eyes, but yes, there is Bryson DeChambeau, the LIV Golf star who is arguably the most popular player in the world right now not named Tiger Woods.

This is a perfect example of why DeChambeau’s popularity has skyrocketed in recent years. His YouTube channel has taken off, as he has aired episodes with former President Donald Trump, six-time major winner Phil Mickelson and former Dallas Cowboys Quarterback Tony Romo. He also seems at peace with playing on LIV, more so than ever before from the perspective of the global fan.

That same mantra applies to his latest Instagram post, which not only trolls but also educates.

In addition to posting his cardboard sign, which every golfer can relate to, DeChambeau added a video to help amateur golfers who struggle with three-putting.

His advice?

Use a ruler to help with speed.

“When you three-putt, it’s best to practice your speed control,” DeChambeau said in the video.

“What works for me is using a ruler and marking 10 feet, 20 feet, 30 feet, and determining how hard you need to hit your putts to (go).”

DeChambeau explains that you should place marks on a yardstick that indicate how far you should bring your putter back in your backswing. He shows you how to place that yardstick on the ground in front of your feet while you practice putting. Different distances require different levels of strength, so this drill can help any wrestling amateur gauge that. You should only bring your putter back so far for a 10-footer, a little more for a 20-footer, a little more for a 30-footer, and so on.

“I can practice a 10-footer, a 20-footer or a 30-footer all day long, and all I’m doing is pointing my foot right where I need to bring the head of the putter back,” DeChambeau adds .

“Over time, that work and practice you put in will build into a feeling. Like, I can look up at you, and I can hit a 10-footer perfectly every time on flat ground.”

He then does the same no-look drill for 20-foot and 30-foot putts, demonstrating his strong feel on the greens.

“For me, that’s what helps me best control my speed and allows me to perform at the highest level,” DeChambeau said.

So to avoid three-putts, you may need to follow DeChambeau’s ruler drill. If it can help him win a few US Opens, it can also help you control your speed on the greens.
