What do pgs.155-158 of the CCA manual say on this? I'm not a CCA level official, just curious as to their recommeded mechanic...always looking for something that may help my own mechanics and thought process.
Thanks

PS..I'm a walker...it's rare that I ever get the opportunity to work 3 man, and as an umpire who just works lower level local SP, FP, (and yes BB), I'm never under the eyes of an observer. But I am a stickler for good solid mechanics that help you in seeing what you need to see and getting you to where you need to be on the field to get the call right.
