Thanks!
It is very helpful to be able to discuss it so I can relay the correct info to the player(parents) so they can learn also.
The ruling on the field was not a thing, because when asked the plate umpire did confer with the base umpire but the BU said he could tell a thing because both teams had on similar color tops and he didn't know who was where.

Oh and he added it's 10U who cares. . .
