THE PUTTING GREEN
Rule 16. The putting Green
Definitions
The 'putting green' is all ground of the hole being played which is specially prepared for putting or otherwise defined as such by the Committee. A ball is on the putting green when any part of it touches the putting green.
The 'line of putt' is the line which the player wishes his ball to take after a stroke on the putting green. Except with respect to Rule 16-1e, the line of putt includes a reasonable distance on either side of the intended line. The line of putt does not extend beyond the hole.
A ball is 'holed' when it is at rest within the circumference of the hole and all of it is below the lovel of the lip of the hole.
