Player's Practice Swing Moves Loose Impediment Which Moves Ball
Q. In making a practice swing near his ball, a player moves a loose impediment (e.g., a stone), which causes his ball in play to move. What is the ruling?
A. The player is deemed to have caused his ball in play to move in breach of Rule 18-2a; he incurs a one-stroke penalty and must replace the ball.
This ruling differs from that in Decision 18-1/8 both because it is reasonably foreseeable that a practice swing will move loose impediments that may in turn cause a ball in play to move, and because a player can, through reasonable care, avoid taking practice swings that might produce such a result. "
So taking a swing and carving out sod that could hit your ball ......is reasonably foreseeable.
