Three out on pitch that just made it to plate!?!

[oneonone]

I was getting ready to call a LL majors game this past weakend and was catching the tail end of a LL junior/majors game (9-10 year olds). Bases were loaded and no outs. The pitcher loses her grip on the ball and releases way early and drives the ball into the groung...it is slowing creeping its way to home plate. Runners on all three bases take off, no movement from any defense. They are all just waiting for the ball to reach the catcher. R1 heads back to third because she must think that the catcher will now be able to just pick up the ball and tag her. PU kills the action. Calls time. Walks back and picks up his rule book and is franticlly looking for something. I'm dressed out and he calls me over and asks if I just saw the same thing and would I have three outs because each runner left their bases before the pitch reached the batter/plate. I say yes and the half inning ends. Only in LL are you treated to rare events like these.
