Scott: "It makes going out on the course less stressful, knowing you're going to putt alright all the time."

AAP's Darren Walton reported these comments from anchorer Adam Scott which, while earnest, probably will be added to the USGA/R&A's circumstantial evidence file.

Long regarded as one of the world's premier ball-strikers and the winner of 18 tournaments globally, Scott admitted during his Open charge at Royal Lytham that his old putting "ups and downs were horrible".

"It eats you up," he told AAP.

"It's such a mental part of the game and for me walking out there feeling really solid with it for the last 18 months, I feel like I'm not ever going to shoot a bad score.

"It makes going out on the course less stressful, knowing you're going to putt alright all the time."

He makes it sound like a drug.
