Looked like a good call by blue. Most unfortunate time to be stepping out of the box by the batter.
It sounds like the reason is "because that's how we always do it". I think that's dumb, and unnecessary. So far no one has given a reason as to what the negative would be about having it relined. Just that we don't, well, because we don't.
I stand corrected...her foot was out of the batters box. The umpire was correct.
Also, I am with the swimcoach on this one. If you watch MLB game, they have a crew of people dragging small fences that drag the field between innings. Takes no time at all.
What you don't see is the grounds crew relining any part of the field. It takes considerably longer to line the boxes than it does for 6 or 7 guys to make a single pass with field drags.
