Thansk for the information.
But my question remains:
Where is the batters supposed to go to avoid intererence and how can see the catchers movement behind him, the catcher may move inside the foul line to throw or outside the foul line?
Under 6.06 (c) the key words are " by stepping out of the batters box" (he stayed within the box) and "or making any other movement that hinders the catcher's paly at home base" (the batter stood still after the pitch, ie no 'movement').
This rule applies if the batter makes an intentional attempt to interfere with the catcher, not if the batter stays within the box and does not move.
