The Man Who Hacked Putting

Mark Sweeney, inventor of the AimPoint putting system, on why it works and how it’s changing the game

In 2004, software developer Mark Sweeney was fed up with missing putts. So he dedicated two years of his life to creating a system that delivers perfect reads. He called it AimPoint. 

Viktor Hovland implemented it and won the Hero World Challenge. Keegan Bradley, Lydia Ko, Adam Scott and more now straddle their line and read their break in finger-widths. Hear from the inventor of this peculiar but effective strategy, as Sweeney and host Tom Coyne dig into something that took 100,000 lines of code to get right. Along the way, you’ll learn how Golf Channel’s virtual putting line came to be, how a group of third graders helped unlock an AimPoint mystery, and why you might already be a much better putter than you think.
