Here’s an interesting new rule which came up last Thursday. This detail is only available in the full rules so I am copying it here for all to see.
Rule 6.2b(6)/1 –Ball That Comes to Rest in Teeing Area Does Not Have to Be Played as it Lies.
Any time a player’s ball is inside the teeing area, the player may move the ball to another spot within the teeing area, and may play it from a tee without penalty.
For example, a player makes his or her first stroke from the teeing area, barely making contact with the ball, and the ball either comes to rest on the ground within the teeing area or remains on the tee.
Since the ball is in the teeing area, the player may play the ball as it lies or, even though the ball is in play, may move the ball to any other spot within the teeing area and play from there without penalty. The player may also place the ball on a tee or adjust the height of the tee the ball is resting on.
