Is It Fair or Foul?--You Make The Call
 
Definition of a Fair Ball--One that settles between home or third base, or that is on or over fair territory when bounding to the outfield past third or first base, or that first falls in fair territory on or beyond first or third base, or that while in or over fair territory, touches the person of an umpire or player. NOTE:  A fair ball will be adjudged according to the relative position of the ball and the fair-foul line, not whether the fielder is in fair or foul territory at the time the ball is touched.
Definition of a Foul Ball--One that settles in foul ground between home and first or third base, or that bounds past first or third base in or over foul territory beyond first or third base, or that while in or over foul territory touches the person of an umpire or player or any object foreign to the natural ground.
A key word in the above definitions is “settles”.  Thus, on all calls between home plate and the bases, it makes no difference where the ball first hits.  It must be adjudged on where it finally comes to rest or is touched.
Also remember these three things:  1) A pebble is part of the natural ground, just as the grass.  2)  All bases including Home plate, are in fair territory and so are the fair-foul lines.  3)  The fair-foul pole is merely a vertical  extension of the fair-foul line.
