Well, as I said before, I'm looking at this as "the runner was obstructed while rounding first base." Splitting the hair of before vs. after, in this sitch, is taking it a little too far. I think I'd protect them between 1st and 2nd, as the OBS, in my judgment, occurred AT 1B.

Cecil, I understand what you are saying; I also understand what Mike is saying.

If F3 is standing on 1st base, or, as stated, "inches off the second base side", I don't just rule based on the "slow down and alter prior to reaching first base." As I see this, the runner was hindered starting then ("prior to"), and continued to be hindered as she turned, and until she was again running in the path she chose, and at the speed she would have had absent the obstruction (and that includes SOME place after the base). So, even though I don't believe that BR is awarded 2nd unless I judge she would have made it, I do believe she needs to be protected if she makes that attempt.

I hope that is what Mike is trying to say; regardless, it is how I rule on any obstruction at or on a base, the one the NCAA calls "rounding" obstruction.

Same idea, different words. Thanks

Me too, and I also agree that the OBS would continue/reoccur after 1st.

It's just that if you don't say OBS affected the BR before 1st, there would be a possibility of a play making an apparent out at 1st. I guess not in the OP the way Bob presented it, but some balls to the outfield are played to 1st; not always expected by the BR.
