Rule of the Day

27-2b/4 Provisional Ball Played from Beyond Where Original Ball Likely to Be But Not Beyond Where Original Ball Found
Q:

A player, believing his tee shot might be lost or on a road defined as out of bounds, played a provisional ball. He searched for his original ball but did not find it. He went forward and played his provisional ball. Then he went further forward and found his original ball in bounds. The original ball must have bounced down the road and then come back into bounds, because it was found much farther from the tee than anticipated. Was the original ball still the ball in play?



A:

No. The player played a stroke with the provisional ball from a point nearer the hole than the place where the original ball was likely to be. When he did so, the provisional ball became the ball in play and the original ball was lost -- Rule 27-2b.

The place where the original ball in fact lay was irrelevant.
