Can't do a suicide squeeze, but you could still run a squeeze play.

Yes, it's called a "safety squeeze."

The LL book says 7.07 only applies to the Junior, Senior, and Big Leagues.

Correct. It's the "evaporation" rule. I have never seen it. Some friends of mine have.

LL asks that on such a play, umps must adjudicate what is the "clean hit" by B1. If the rock doesn't leave the infield and no outs are recorded, R3 "vanishes."

LL umpires around here call it the "poof" rule, as it "poof....he disappeared."

What started out as a pitching motion ended up as a throw to the plate... Balk! They'll call a balk if the catcher leaves the box before the ball leaves the pitcher's hand.

As long as the pitcher continued to a make legal pitching delivery, it is still a pitch and not a throw.

A pitcher may disengage and throw to home.

Nope. It's still a pitch.

The interpretation in use is that the catcher cannot move from the box until the time of the pitch - which is when the motion commits the pitcher to pitch.

That's the rule (on an IBB), but I've never seen it called and I hope I never do.

I'm just wondering how a catcher would know a safety squeeze is on if R3 does not leave the base until the ball reaches the plate (Normal LL), or, why he would see a need to step in front of the plate.

I called a walk off balk in Fall ball, with R2 and R3 and 1 out, when the catcher stepped out of the box by at least 6 feet, before the pitcher even started his motion, but he started as soon as catcher was in place out of the box. At every plate meeting the coaches talked about balks (I did not bring it up), they wanted us to call balks so the kids can learn during Fall ball, no warnings.

DG....no balk here. It can only be called if it's an IBB. Without the IBB, I would not let the pitcher pitch until the catcher set up correctly. I have never had this happen, but this is how I would handle it.

Given the game situation I'd bet a lot that it was an IBB.

Opps....After reading it again, I wouldn't take that bet. :o

When coaches say that, usually they are looking for reinforcement of what they've been warning their pitchers about. I doubt "the lesson" you taught them was on their radar.

I am pretty sure that one was not on their radar. I overhead the manager telling the league commissioner after the game that a game should not end that way, and I agree, properly instructed catcher will not do that, and if a pitcher saw him step out he should have stepped off and called for a meeting instead of starting his motion. I doubt there was any player or coach in the league who did not hear about it, so I don't expect it will happen in the Spring.
