If you had never previously thought about a putter custom fitting before, we are pretty confident you will be considering it after reading TaylorMade's account of Dustin Johnson's new T-line on his putter.
Johnson, who won by a commanding eight strokes in the 2018 opener at the Tournament of Champions in Hawaii, not only stuck a new TaylorMade M4 driver in the bag, but also relied on a brand new sightline on his Spider Tour Black putter.
After recently throwing away a big lead at the WGC-HSBC Champions after a poor display on the greens using a Spider Tour Black without any sightline, Johnson headed to TaylorMade's putting lab in Carlsbad where he worked his way through a number of models with differing sightlines.
The takeaway from TaylorMade's comments was that Johnson had been aiming up to 10 inches left of his target with a long sightline! That's where the T-line came in and changed it all.
"Dustin was struggling with his putting end of last season, punctuated by his lost lead in China after struggling on the greens," said TaylorMade.
"Keith Sbarbaro [his fitter and VP of Tour Relations] met with him in Carlsbad at the putter lab to solve his woes.
"The Tour team built 12 identical Spider Tours, each with different sight lines (long, short, dots, etc.). He hit 5 putts (flat, 15 footers) with each sightline in the lab.
"The putters with the long lines he was aiming upwards of 10 inches left of the hole. The short line model(s) he lined up left edge.
"The one he used all last year with no line was 1 inch left of centre, but the “T-line” model was right at dead centre nearly every putt."
So there you have it, folks. Putter custom fitting really does work, and the results were very much clear for all to see at Kapalua last week.
