It's Saturday. You're driving down the road, maybe going to the golf course or to a college football game with family or friends.

And then, suddenly, out of nowhere, you do a huge double-take. To your right stands the reigning US Open champion, holding up a cardboard sign that reads, “Send This To A Friend Who Always 3 Putts.” You can't believe your eyes, but yes, there's Bryson DeChambeau, the LIV golf star who may be the most popular player in the world right now and isn't named Tiger Woods.

This is a perfect example of why DeChambeau's popularity has skyrocketed in recent years. His YouTube channel is successful 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 happy at LIV, taking into account the perspective of global fans more than ever before.

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

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

His advice?

Use a ruler to increase speed.

“When you're three-putting, the best thing you can do is practice your speed control,” DeChambeau said in the video.

“What works for me is to use a ruler and mark 10 feet, 20 feet, 30 feet and determine how hard you have to hit your putts to go.”

DeChambeau explains that you should put marks on a yardstick that indicate how far back you should take your putter on the backswing. He shows how you should place the yardstick on the ground in front of your feet when putting. Different distances require different levels of power, so this drill can help any amateur who is having difficulty assess this. With a 10-foot putter you should only bring your putter back so far, with a 20-foot putter a little more, with a 30-foot putter a little more, and so on.

“I can practice a 10-footer, a 20-footer, or a 30-footer all day long, and all I do is point my foot exactly where I need to return the putter head” adds DeChambeau.

“Over time, the work and practice you apply will solidify into a feeling. For example, I can look up at you and hit a 10-footer perfectly every time on a flat surface.”

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

“For me, it’s what helps me best control my speed and perform at my best,” DeChambeau said.

So to avoid three-putts, you might want to stick to DeChambeau's ruler drill. If it can help you win two US Opens, it can also help you control your speed on the greens.
