Another 2 questions?

[t2nyval]

Sorry for asking questions the book spells out but, here are another 2 from little league.

1) R2, pitcher misses throw back from catcher and R@ jumps off the bag, picks up the ball and throws it back to the pitcher. Whats the ruling.

2) Pitch approaches WAY outside, surprisingly before the ball even makes it to home plate, batter wildly jumps out of the box as if the pitch is going to hit him!??(I dont know what he is looking at!!) Whats this call. Thanks, Tony
