Dustin Johnson makes good use of a cart path at The Memorial

Dustin Johnson played arguably the most unusual shot of the PGA Tour season as he used a cart path to his advantage during the final round of The Memorial.

Johnson was tied for the lead after playing a flawless outward 33 at Muirfield Village, but he looked set to have his card wrecked at the 10th hole when he pulled his drive way left and into the shubbery.

With no route to the green, even pitching back to the fairway was off limits as he considered taking a penalty drop, but the solution he came up with could only be described as inventive.

Johnson managed to stab his ball out of the bushes and onto a nearby cart path, and the race was on as marshalls, cameramen, Johnson and Sky Sports on-course reporter Wayne Riley gave chase.

With the path favourably sloping in the right direction, Johnson's ball followed the contours and rolled almost 50 yards before finally coming to rest in the middle of the concrete.

And after taking a free drop onto the nearest patch of grass, Johnson clipped a superb third shot to 12 feet but was unable to hole the putt that would have salvaged one of the best pars of the year.
