Simply wanted to show you this video about a player who is not too lucky:
As you can see, the ball ended one yard behind (!) the spot, where he played from… and thus the stroke is (hopefully!) not too good for his driving-length-statistics….
Rule 6.2 allows him to tee the ball (without penalty) within the teeing area and play his second stroke – last year he did not have that option (or rather: he did have that option but it would cost him a one stroke penalty).
Hopefully the second stroke will be better than the first… :-).
