IP's again...

[SRW]

I've been studying ASA's Rule 6 for illegal pitches lately, and had some field experiences that raised some questions in my mind. In all cases, assume you're the BU.

1) You notice a leap. You give the DDB signal and say "illegal". The PU calls a strike on the pitch (batter didn't swing). What's the propper mechanic from this point on? Do you, as BU, call Dead Ball, and essentially reverse the PU's called strike?

1a) What if that called strike was strike 3?

2) Same as #1 except PU calls a ball. Do you call dead ball and raise a fuss only to get a called ball changed to an IP? Is it worth even calling DB for?

3) You notice the leap, give the DDB, state "illegal". The BR pops it up to F7, who makes the catch. Assume B3 tags and makes it to 2B safely. When you then call time, and go to the offensive coach to see if he wants the "result of the play", should the PU join you in the conference?

All help and rule cites, POE's, mechanics, etc. would be helpful. Thanks!
