My first question on the 1B play would be is "oversliding" the same thing as "overrunning?" My first thought was that it is not, but I don't own a LL rule book. Can this be supported by rule? How about ASA? Occasionally I do see runners sliding into first, but this
is the first time I've seen an overslide into first.
My second thought was that she had passed first, so it was one-big-bag and thus did not matter. But obviously that's an ASA rule and not LL. Big surprise there.
