Did you see the flap today on the PGA tour with Padraig Harrington? After completing his round, he was told that he may have teed up in front of the tee markers on one of the last holes.
What does Rule 11 say about teeing from outside of the teeing ground?
In stroke play, you incur a two-stroke penalty and you must correct your mistake before teeing off on the next hole or, in the case of the last hole of the round, declaring your intention to correct your mistake before leaving the green. If the mistake is not corrected, you are disqualified. That would have been Padraig’s fate if the officials had agreed that there was an infraction.
In match play, your opponent may require you to replay the shot. This must be done immediately and there is no penalty involved.
If you’ve ever found yourself in this situation, I’m pretty sure you won’t make that mistake again. I know I won’t.
By the way, do you know the specific parameters of the teeing ground? It is a “rectangular area two club-lengths in depth, the front and sides of which are defined by the outside limits of two tee-markers.”
