The “line of putt’’ is the line that 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.
“Loose impediments’’ are natural objects including: • stones, leaves, twigs, branches and the like, dung, and worms and insects and casts or heaps made by them, provided they are not: fixed or growing, solidly embedded, or adhering to the ball. Sand and loose soil are loose impediments on the putting green, but not elsewhere. Snow and natural ice, other than frost, are either casual water or loose impediments, at the option of the player. Dew and frost are not loose impediments.
A ball is deemed “lost’’ if:
a. It is not found or identified as his by the player within five minutes after the player’s side or his or their caddies have begun to search for it; or
b. The player has made a stroke at a substituted ball; or
c. The player has made a stroke at a provisional ball from the place where the original ball is likely to be or from a point nearer the hole than that place.
Time spent in playing a wrong ball is not counted in the five-minute period allowed for search.
A “marker’’ is one who is appointed by the Committee to record a competitor’s score in stroke play. He may be a fellow-competitor.. He is not a referee.
Single: A match in which one plays against another.
Threesome: A match in which one plays against two, and each side plays one ball.
Foursome: A match in which two play against two, and each side plays one ball.
Three-Ball: A match-play competition in which three play against one another, each playing his own ball. Each player is playing two distinct matches.
Best-Ball: A match in which one plays against the better ball of two or the best ball of three players.
Four-Ball: A match in which two play their better ball against the better ball of two other players.
A ball is deemed to have “moved’’ if it leaves its position and comes to rest in any other place.
The “nearest point of relief” is the reference point for taking relief without penalty from interference by an immovable obstruction (Rule 24-2), an abnormal ground condition (Rule 25-1) or a wrong putting green (Rule 25-3).
It is the point on the course nearest to where the ball lies:
(i) that is not nearer the hole, and
(ii) where, if the ball were so positioned, no interference by the condition from which relief is sought would exist for the stroke the player would have made from the original position if the condition were not there.
Note: In order to determine the nearest point of relief accurately, the player should use the club with which he would have made his next stroke if the condition were not there to simulate the address position, direction of play and swing for such a stroke.
An “observer’’ is one who is appointed by the Committee to assist a referee to decide questions of fact and to report to him any breach of a Rule. An observer should not attend the flagstick, stand at or mark the position of the hole, or lift the ball or mark its position.
