RULE 20/1 CLUB TO BE USED IN MEASURING
Q: A player, taking a relief under a Rule, uses his driver to measure the one club-length or two club-lengths prescribed in the relevant Rule. He drops a ball correctly and the ball rolls less than two driver-lengths, but more than two putter-lengths, from where the ball first struck a part of the course when dropped.
Under Rule 20-2c, a dropped ball must be re-dropped if it rolls more than two club-lengths. If the ball comes to rest in a poor lie, may the player opt to use his putter to measure the distance his ball has rolled, in which case he would re-drop under Rule 20-2c and escape the poor lie?
A: No. The player must continue to use the club he originally used for measuring for all measuring in a given situation.
