Jason Dufner's approach to his putting has changed dramatically over the past few seasons. When Secret Golf met up with Jason at his home course in Auburn, Alabama in 2016, he had no interest in even shooting a putting video, even going so far as to say that he didn't even like looking at his putter.
Fast forward to 2018, however, and his outlook on his flatstick has seen a complete 180. With the introduction of Blast Golf Technology to his short game, he has been able to very accurately analyze every parameter of his putting stroke, and more efficiently go about making improvements- much like he is renowned for doing with Trackman and his long game.
We will get to what Jason is working on specifically, but first, a little more on Blast Golf, and the parameters it uses to analyze your stroke.

As a quarter-sized unit that you simply attach to the butt end of your putter grip, Blast Golf packs an incredibly thorough punch in analyzing your putting stroke. While it breaks the motion down into 12 different categories that affect your putting, today we will be focusing on 4 of them; loft change, rotational change, lie change, and tempo.
- Loft Change: Loft is the angle of the putter face in relation to a line perpendicular to the ground. The loft at impact should be the same loft as when you addressed the ball (0 degrees of loft change.) Any decrease in loft will drive the ball into the ground, any increase in loft will send the ball into the air.
- Lie Change: The lie of your putter is the angle created between the ground and the shaft. An increased lie at impact would cause the putter face to be aimed to the right, while a decreased lie would cause the putter face to be pointed to the left (for a right handed golfer.). The lie of the putter should be the same at address and impact.
- Rotational change: The rotation of the putter is where the putter is aimed at address versus where it is aimed at impact. Rotational change open would mean the putter is aimed to the right of the address position, rotational change closed would be a putter face aimed left of the address position at impact. You want the putter aimed at the same place at address and impact (0 degrees of rotational change).
And that brings us to Duf's major area of emphasis- Tempo. In the video below, he explains his keys:
The biggest takeaway from Duf's experience with Blast Motion is in the 2:1 ratio of back stroke time to forward stroke time (tempo). This just means that if his back stroke takes .6 seconds, his forward stroke should take .3 seconds.
He finds that if this ratio is not maintained, it is because his stroke is excessively handsy, and he didn't use the big muscles of his thorax to power the putt. The more he uses the big muscles in his torso, the easier it is to maintain the constant 2:1 ratio of his tempo.
Though technical in nature, this technology has ultimately helped Duf simplify the process of improving both his putting stroke and his confidence.
