Slot Machine: Cash In on Eyeline Golf’s New Slot Trainer

With the help of Eyeline Golf’s new putting aid, you could soon be rolling them in from everywhere.

Three weeks ago, Justin Rose Instagrammed a photo of himself on the practice putting green ahead of the first round of the BMW Championship at Wentworth Golf Club in England. Pinned to the ground with a couple of tees was a low-profile, simple-looking putting trainer with which the 2013 US Open champion was clearly trying to groove a sound swing path and perfect the angle of his putterface at impact.

Thanks in part to that training aid, Rose went 183 consecutive holes without a three-putt, dating back to this year's Masters.

Yesterday at the Memorial, he might have missed the par putt that would have extended the playoff with Sweden’s David Lingmerth. But he snaked in a monumental one on the first playoff hole.

We saw all week how simple and efficient Rose’s stroke was, a testimony not only to years of practice but also the effectiveness of the Slot Trainer, created by Jim McLean and his son Jon, and brought to market by Denver-based Eyeline Golf.

Jon McLean, a mini-tour player in Florida, conceived the Slot Trainer. At only one-sixteenth of an inch thick does not impede the movement of the putter head, and which allows you to roll the ball over grass rather than plastic.

The putter head fits between two tees four and a half to five inches apart helping to improve your alignment, and the narrow gate 11 inches away, and formed by tees two and a half inches apart, allows only well-struck, on-line putts to pass through.

The McLeans approached Eyeline Golf founder Sam Froggatte with a view to mass-producing the putting aid and Froggatte took a few samples to Pinehurst last year for the US Open.

One player who instantly took a liking to it and asked to keep one was Brooks Koepka who has since won the Turkish Airlines Open on the European Tour and the Waste Management Open in Phoenix. Charley Hoffman, Greg Chalmers and a number of other Tour players also use the Slot Trainer to help improve their putting stats.

Spend a few days working with the Slot Trainer and your putting stats are more or less guaranteed to look better too.

The Slot Trainer is available for $50 at
