I've always hated that ground-rule double rule. Should be discretionary. If there's a runner who clearly looks like he would score from first, then he should be allowed to score. Much more logical than just making an absolute rule like that. Maybe it was fine in the early days of baseball, when guys were slower, but it should be changed for todays' game, when many runners could score from 1st on a hit like that. The umps should have discretion on whether the runner would score or not from 1st. Maybe they all get together, and sort of have a vote, and if a majority thinks the runner would score, then he scores. Just seems right to me.
