Besides, if you turn to Page One of your unofficial umpire's manual, you will note the first sentence reads "When in doubt, get an out."
Somewhat more seriously, I do not have obs here as the play is described. If,
in the sole judgement of the umpire, there is no frickin way she was going to get to the bag before being put out, there is no obs.
Caveat: It is a judgement call. If the BU rules obs, then it's obs. We might visit about it out back after the game, but it is a judgement call.
