A player marks his ball on the green.

Question:
Whilst picking up or replacing the ball, he accidentally moves it slightly.
Or: Whilst preparing to putt (e.g. by touching it with the putter), the ball moves ever so slightly.
Is there a penalty?
Answer:
Rule 13.1d states:
If the ball or the ball marker is accidentally moved by the player on the green,
- → no penalty
- → The ball must simply be replaced on its original spot.
This applies, for example, to:
- marking
- picking up
- replacing
- accidental contact with a club or foot

Anyone who says, ‘Let’s not be too strict about the rules of golf – we’re not playing “The Open” after all’, is playing some sort of ball game, but certainly not golf.
Fundamentally, golf is all about the ‘Spirit of the Game’
