According to a study by Top 100 Teacher Marius Filmalter, the best putters in the world hit slightly up on the ball, adding at least 1.7 degrees of loft to their stroke at impact. This causes the ball to roll immediately forward (as opposed to caroming off the green surface) and to hold its line. Putting is about precision; hit down on the ball even slightly and it could jump off line. The good news? You can train yourself to hit the ball with the right amount of loft. Your lesson “fee”? A mere 75 cents.
