Definition

The “teeing ground’’ is the starting place for the hole to be played. It is a rectangular area two club-lengths in depth, the front and the sides of which are defined by the outside limits of two tee-markers. A ball is outside the teeing ground when all of it lies outside the teeing ground.

11-1. Teeing

In teeing, the ball may be placed on the ground, on an irregularity of surface created by the player on the ground or on a tee, sand or other substance in order to raise it off the ground.

A player may stand outside the teeing ground to play a ball within it.

11-2. Tee-Markers

Before a player plays his first stroke with any ball from the teeing ground of the hole being played, the tee-markers are deemed to be fixed. In such circumstances, if the player moves or allows to be moved a tee-marker for the purpose of avoiding interference with his stance, the area of his intended swing or his line of play, he shall incur the penalty for a breach of Rule 13-2.

11-3. Ball Falling Off Tee

If a ball, when not in play, falls off a tee or is knocked off a tee by the player in addressing it, it may be re-teed without penalty, but if a stroke is made at the ball in these circumstances, whether the ball is moving or not, the stroke counts but no penalty is incurred.

11-4. Playing from Outside Teeing Ground

a. Match Play
If a player, when starting a hole, plays a ball from outside the teeing ground, the opponent may immediately require the player to cancel the stroke so played and play a ball from within the teeing ground, without penalty.

b. Stroke Play

If a competitor, when starting a hole, plays a ball from outside the teeing ground, he shall incur a penalty of two strokes and shall then play a ball from within the teeing ground.

If the competitor plays a stroke from the next teeing ground without first correcting his mistake or, in the case of the last hole of the round, leaves the putting green without first declaring his intention to correct his mistake, he shall be disqualified

The stroke from outside the teeing ground and any subsequent strokes by the competitor on the hole prior to his correction of the mistake do not count in his score.

11-5. Playing from Wrong Teeing Ground

The provisions of Rule 11-4 apply.
