Umpires, Interference or Obstruction?

Umpires, yeah umpires I'm talking to you. Well of course just about anyone else on the planet who loves baseball. Just wanted to let everyone know there are unwritten rule wording that is being kept from you that determine outcomes in playing actions and potentially games.  

Unwritten rules language can be problematic. For instance: Runner makes contact with defensive player fielding a misplayed ball or defensive player fielding a misplayed ball makes contact with runner, now go to the rule book and look it up and let me know what the rule book says.

Here is what it does not say:  The simple act of making contact is just a needed element in determining interference or obstruction on a misplayed ball.  When contact is made with or by a runner the most important element in determining when it is interference or obstruction on a misplayed ball are the specifics regarding the location of the defensive player at the time of contact, but those specifics are not stated in the rule book.  

From the defensive player's original position he has a (step & a reach) to play a misplayed ball,  if contact is made within this area interference would still be called. 

If the defensive player goes beyond a (step & a reach) to play a misplayed ball and contact is made the runner is now protected and obstruction would be called.  The one exception is if the runner intentionally runs into the defensive man, then it would still be interference.
