charliej47 wroteRULE 9. BASE RUNNING
Sec. 6. A batter-runner is awarded first base if:
A. He is a runner because of c, d or e of section 5
B. A fair ball, other than an infield fly, becomes dead and provided a preceding runner or retired runner does not interfere in such a way as to
prevent an obvious double play.
NOTE: Unless awarded first base as above, a batter-runner is entitled to first base only if the batter-runner reaches it before being tagged out, thrown out or called out for hitting an infield fly.
What rule book are you quoting? (Year, etc.?)
This wording is not quite what the 2010 rule book says in that same rule (Rule 8-5). I should have also said fastpitch, since U-trip has two separate rule books for fast and slow pitch, but I wouldn't have thought the ruling would be different.
Nonetheless, the current rule book does have the same wording as "B" that you quoted (8-5-D) and the same note, but this cannot be meant to apply to ALL situations where a batted ball becomes dead, since that would directly contradict the majority of Rule 8-14. Awarded Bases, including some very obvious awards (home run, fair ball bouncing over the fence (GRD), etc., etc.).
I chalk this up to goofy rule book wording, since they must be talking about "at least" 1B, not at most.
