Obstruction - Rounding the bag

You see it you call it. I grant that as PU and 60-90 feet away, the OBS needs to be a little more obvious to be called - but if you see OBS - whether PU or BU, you call it.

Like I said, I suppose this may be regional ... I would never take umbrage at a partner PU that called an OBS on the bases. OBS just takes an instant, and it is usually away from the play - there are a huge number of reasons a BU could miss an OBS without doing anything wrong.

Clears up my question (along with your other reply) as to what you were saying.
'Passed on" (a phrase used often by basketball refs when discussing plays) was a bad choice of words on my part.
No disagreement that a BU can miss an OBS without having done anything wrong.
What piqued my curiosity when I read your post had more to do with something that happened to me earlier this season.
Two man. I'm BU 2 outs R1 on 1st.
Ground ball to F4, in quick order I have R1 jumping over the ball as F4 is ranging to her right to try to backhand it, the ball is just by F4's out stretched glove hand as R1 comes down on her as she completes her jump over the grounder, they get tangled up. I'm processing all this (do I have INT? or do I have nothing?) when PU, (who is inside the diamond between the circle and the 1st baseline about even with the pitchers plate) calls R1 out for INT.
Now maybe I was too slow in determining what I had on the play, too slow in giving a safe signal if I had nothing, or a dead ball signal for iNT, but he decided he saw something and I didn't and he was going to make call.
Yes any ump can call INT or OBS, I just felt that the call was mine. This was not a case my not being in position to see what was happening, I was looking right at it and the PU just "jumped the call".
