Lewred14,
If an umpire is actually telling you this in your games ("no contact, no obstruction"
you have my sympathy, for you have ill-informed umpires.
Obstruction does not require contact. But there is another element required for an obstruction call that may or may not have happened on your play.
To have obstruction, you must have two things:
1) a fielder not in possession of the ball.
2) a runner that is actually impeded.
Absent either one of these elements, you cannot have obstruction.
Blocking the base alone and in itself is not enough for obstruction.
An "impeded" runner is one that alters her path to the base, slows down, tries to go around, slides and makes contact with the fielder or is otherwise prevented from taking the route to the base of her choosing by a fielder not in possession of the ball.
What can a coach do if he feels his runner has been obstructed? Here is the approach I would take. When I wa coaching a few years ago, I actually had a "no obstruction" call reversed this way.
Calmly request time. When granted, calmly approach the umpire and maintain a level, non-aggresive tone. (This is a good start whenever you need to talk to the umpire).
Start off with, "I have a question about that play. Did you see my runner (fill in the blank: slow down, change directions, slide into and make contact, go around...whichever fits the play)?"
If the answer is "no", you're pretty much shot down right there! In the umpire's judgement the runner was not impeded.
If "yes"...
Next ask, "When my runner (slowed, altered, etc.) did the catcher have possession of the ball?"
If "yes", again you might as well stop right there. In the umpire's judgement the catcher had the ball.
If "no"...
Restate what you have now confirmed. For instance, you could say, "So my runner was impeded and the fielder did not have possession of the ball. Is that what you've just told me?".
Unless the umpire changes his tune mid-stream, that is exactly what he has just told you. Hopefully, you can get a "yes" to that one!
Then ask, "So why didn't you call obstruction?" Stand back and wait for an answer.
If the umpire says anything about "there must be contact" or that the catcher was "about to receive the ball", listen to his answer then when he is finished, the first words out of your mouth should be....
"I'd like to file a protest".
You are no longer protesting a judgement call. The umpire has confirmed his judgement for you (since you asked the right questions!) and you are now protesting a misapplication of the rules.
As the protest is logged, be sure that it is clearly recorded that the umpire confirmed your runner was impeded and that the fielder did not possess the ball. These two points are the key to having your protest upheld.
Now, just cross your fingers and hope that whoever is reviewing the protest has some idea of the proper rule and its application! If they do, this is a 100% winnable protest. That's the tricky part, but the odds should be in your favor.
Then again, all your well-laid groundwork could be crushed by a tournamnent director that has no clue on the proper rule. That happened to me this past weekend when a TD overruled a call I made regarding base awards. The TD was clearly wrong, but their word was final.
These tyes of calls can be successfully protested, if you follow ask the right questions and word your protest correctly.
