If I did not know any better...

Tim, or someone else of extensive experience,

Please explain a reasonable philosophy for this situation.

Catcher sets up outside... calling for a pitch that should be outside the plate. Pitcher 'misses' his mark and the pitch comes down the tube/middle of the plate.

I've had other umpires tell me that they would not call that pitch a strike because the pitcher missed his mark.

What is expected of a top-flight umpire here? I see three options:

1) Does the strike zone move way outside - call a strike when the pitcher hits his mark even though the pitch is not over the plate?
-or-
2) Do I assume the battery has given up opportunity to pitch a strike - If he does hits his mark it will not be over the plate and therefore a ball? If he does not hit his mark, it should also be a ball even if that 'miss' is over the plate.
-or-
3) Should I continue to call balls and strike based upon the position of the ball relative to the batter?

Option #1 does not seem reasonable. Option #2 has merits. But to date, I've always chosen option #3 - no change from any other pitch. Additionally, I do not change my viewing position behind the plate. Should I be considering some other options?

The majority of my ball is High School Varsity and slightly older American Legion. Does the level of ball make a difference on how this scenario should be called?

Thanks in advance for your help.
