Did he go?

[Robert G]

Runners on 1st & 2nd, I am PU, Bu is in C Slot.
B1 checks his swing & I ask my partner for Help "did he go"?
I caught him off guard & he did not react right away then gave the safe sign.Was I wrong for asking for his help with a right hand batter up? What if it was a lefty up?

2- I understand the V in a 2 man crew, but with none on & f8 makes a great catch in center who's call would it be?

3- Do you (PU) signal verbally when a infielder makes a catch at his shoe tops?
Thanks, Robert
