Asking for help from feloow umpire

[sabattis]

In working a 2-man umpiring crew under major league rules, is there ever a situation when the Base Umpire, upon request by the offense, should ask for help from the Plate Umpire when the call was clearly a judgment call of the responsibility of the Base Umpire? If so, when? For example, the Base Umpire is in B position with 2 outs and runners on 1st and 3rd. The pitcher throws in an attempt to pick off the runner at 3rd. Obviously, the base umpire needs to make a call (say “out” in this case) – however, if the offense asks the base umpire for “help” (that is, ask the Plate Umpire if he saw anything different), should the Base Umpire ask the Plate Umpire for “help?”
