Interference??

[JEL]

Backing up is legal (except BR going to first). If this were not so, each time a runner leads with the pitch, and then returns we would have an out. Likewise, a return to touch a missed base, return to tag-up, etc all would be automatic outs!......hmmm, maybe I like that!

Don't confuse with running in reverse order to make a travesty of the game though, that is a no-no.

IMHO also, cited case was not intereference. On another thread, the value of umpiring 10U, and even 8U ball is being discussed. Here is a prime example of rules knowledge one will gain if calling in the younger age groups. You can call for years in 18U A Gold and never see a play such as this. If it can happen, it will happen in 10U, you gotta know your stuff to call these games.
