Tip From the Archives
You are having difficulty reading the break in the green.
In addition to checking the grain of the grass and line from your ball to the hole, you should also try using the plumb bob technique to help read the roll of the green.
Learn how to plumb bob the line by standing behind the ball and look straight down the line to the hole. Hold the putter with your thumb and index finger so that it hangs down as your arm is stretched out in front of you. Block the view of the ball with the lower end of the shaft of the club. Now keep only your dominant eye open. Does the hole now appear to be on the left or the right of the shaft? If the hole looks like it is on the right of the shaft, then you should expect the putt to break the right. If the hole looks like it is on the left of the shaft, then you should expect the break to be from the right to the left. If it appears to be directly behind the shaft, then you should aim straight at the hole because there is not likely to be any directional roll due to the break.
