Asking for help from feloow umpire

[GarthB]

WIth runners on 1st and 3rd what are you doing in position B? Position C is the correct mechanic....

Really?

From the Manual for the Two-Umpire System, published by Umpire Development Program:

Section 7 "Runners on First and Third"

7.1 Positioning

"With runners on 1st and 3rd, the base umpire will position himself in exactly the same manner as with a runner on 1st base only. (see Section 3.1)"

Of course, Section 3.1 does an excellent job of defining position "B".
