Even if you aim perfectly to allow for the exact break of a putt if you then roll your ball too fast it will miss above the hole. And if you roll it too slowly it will likely miss below the cup.
You can’t dominate with your putter if you don’t know how to aim it correctly or how much break to play. Nail these fundamentals first. If you hook or cut-spin your putts your chance of success goes down. If your putts roll off the face in the same direction your putter is heading immediately after impact that’s good. If your putter moves one way and the ball another you’ve got problems.
The seventh hole at Shinnecock Hills is the ultimate example of why you need to leave approach shots below the hole on severely sloping greens. As you watch the Open count how many times the players who end up above or right of the pin on No. 7 wind up three-putting. It was a pivotal hole in the 2004 U.S. Open. Expect more of the same this year.
