I thought this was a great example of how sometimes a player can do just about everything wrong and still get away with it. Jimmy Walker grossly under-reads this 5 foot, left to right breaking putt, lines the line up on the ball to his read, then proceeds to take his putter outside and loop it out even more so that it pulls the ball at least a cup left of the hole, after which the ball sneaks in the far right side of the cup. My take on this is that Walker instinctively and subconsciously knew that the putt was going to break way more than he read, and by the time he pulled the trigger he just maneuvered the putter to get the ball rolling on the correct line. He won the tournament, and it certainly helps when putts like this that should never go in just go in anyway. This is also one of the reasons I never use the line on the ball when I putt. I tried it a few times and could never get comfortable with where the line was aiming. I would often make my final read when over the putt, and by that time, if the read had changed, the line was a major distraction.
