Xander Schauffele, during the first round of the Memorial, began using an arm-lock putting grip. He also said it should be banned.

Is arm-lock putting the cheat code everyone thinks it is? I put Bryson DeChambeau's putter to the test to find out. Here are the results.

At the World Scientific Congress of Golf last year, researcher Dr. Andy Hoffer looked at the arm-lock method of putting specifically, and how it helped golfers with tremors or yips.

Apparently, Schauffele ditched the new putting method prior to the weekend at the Scottish Open, where he went on to tie for 10th.
