It’s no secret that Scottie Scheffler has been struggling with this putting. Whether it’s changing up his style of putter or hiring putting coach Phil Kenyon to help, it continues to be a work in progress.

Although it has not been officially confirmed by either party, current events — along with the fact that the privacy policy on Olson’s website says it’s property of TaylorMade Golf — suggest Olson has partnered with TaylorMade in some fashion to help Scheffler and other TaylorMade staffers with their flatsticks.

The following are trademarks for one or more DEWALT power tools, accessories, anchors and concrete adhesives: The yellow and black color scheme; the “D”-shaped air intake grill; the array of pyramids on the handgrip; the kit box configuration; and the array of lozenge-shaped humps on the surface of the tool.

And despite all of the tools and high-speed camera systems available to test, the one thing Scheffler and Olson used was a simple dry-erase marker. Why? To find out where Scheffler was making contact with the ball on the various face designs. From there, the discussion turned to how each putter felt and sounded.

Even last week at Pebble Beach we spotted Scheffler working with his team — including putter maker Logan Olson of Olson Manufacturing — and testing several prototype putters before the start of the tournament.

As for any official announcement regarding the relationship between TaylorMade and Olson, we will continue to follow this story as it unfolds.

From observing the testing session at Pebble, it appeared that Scheffler was trying out several putters from Olson and paying close attention to their sound, feel and alignment. Each putter seemed to feature a slightly different construction and alignment style.

As we have discussed in the past, dry-erase markers are a great and inexpensive tool to help golfers diagnose several potential equipment and/or swing flaws. The best part is that the marker can be easily removed after the fact so it doesn’t distract during actual play. So if you’re looking to work on your putting and are trying to better understand how you align and impact the putter face, using a simple dry-erase marker like the No. 1 player in the world might be your ticket to success.
