Putting

推杆- Putter是一个Golfer球包里最重要的一根球杆。而推杆的好坏直接影响一场球的最终成绩。

The USGA statistics states the average male golfer shoots a 98-99 and has at least 40 putts per round or 2.2 putts per hole. Most recreational and amateur golfers are well above this number while professional golfers average about 1.8 putts per hole and 32 putts per round.

世界排名前十的PGA选手，平均推杆是1.6。

推杆三要素：初始方向、果岭判读以及距离感知。可以解释为：杆面的瞄准方向，阅读果岭的折点（break）以及推杆的力度控制。第三点最重要是距离的控制，即speed。

Setup:

There are four main elements to the setup: 1) putter face alignment; 2)shoulders alignment; 3) ball position; 4) eyes over target line.

1) It is important that the putter face is set up square to the starting line of the putt. It is easier to return the clubface to square if no manipulation is involved.

2) The shoulders should be square (parallel) to the starting line in order for the putter path to be correct. Whether the golfer favours a straight-back and straight-through stroke or one that arcs to the inside, square shoulders promote a proper path.

3) Ball position should be just ahead of where the putter’s arc bottoms out during the stroke. This to assure hitting up slightly on the ball through impact, which is the optimal way to contact the ball.

4) The eyes should be over the target line for proper visual accuracy. They can also be slightly to the inside, but never to the outside.

对于Toe-Weighted的推杆，要根据设计多与少的不同来设定Arch多少来推击。只有通过Arch才能把球推正，用直上直下的推击方式，很容易关闭，球向左方向滚出。

对于Face-Balanced的推杆，如果用Arch的方式推击，杆面很容易打开，球向右方向滚出。用直上直下的推击，球会直向滚出。

Plumb Bob瞄准法比较适合只有一个拐点的中短距离推杆，在长推或者多重拐点的推杆效果不佳。在你要面对中短推但不确定拐点的时候，这是一个很好的工具。它能让你知道自己在推哪一个方向，有自信的去完成这一杆，但最好的效果仍然是结合多种方法，譬如看看草纹，看同组球员的走线情况，看不同角度的果岭坡度。
