OBR Obstruction: B becomes A - Play

[mikebran]

R1 only. No outs.

Hard groundball single, R1 rounds 2nd and is OBSTRUCTED by SS, as charging RFer has scooped and preparing to throw.

(Obviously, this is type B obstruction). Baseumpire makes the call and makes mental decision to PROTECT this runner into 3rd. and moves into position as throw is made to 3rd, a catch, a slide, a tag, a (what?).

Now in real time, the thirdbaseman, who knows he just tagged this runner 4 inches off the bag now alertly throws to 2nd to play on the advancing batter runner.

QUESTION in the form of a comment:

BU observing the tag of R1 that would be and OUT cannot CALL out, so he calls "TIME" and announces the obstruction and places R1 at third. But does this then make the throw to 2nd irrelevant, and is the placement of the B-R simply based on the umpires opinion as to WHERE B-R would have ended up?

(assumption: umpire would err on the side of allowing B-R second).

assumption 2: if someone is going to say that the play at third REQUIRES a call of "OUT" first, I'd like to see "documentation".

More: flashback from lists from the past, but isn't this an example of Type B "becoming" Type A?
