Missed no putt under 10 feet. Beat an elite, international field by 12 shots, setting 20 tournament records along the way. Throw in a loose bogey and you have the 40. Then I had three or four more chances to make birdies coming down the stretch. I definitely think 18 under can be broken.
Guys are just better athletes, better players.
The equipment helps. I know records are meant to be broken, and that one will fall. It's just a matter of time. After shooting the front-nine 40, El Tigre was perfection in his first Masters appearance as a professional. He shot 30 on the back to salvage an opening 70 - and got only better.
