Suicide Squeeze Coverage-Two man Crew

[gsf23]

Had this situation come up in a college game I played in about 10 years ago. We were in the field, other team had R2 at second, R3 and third, no outs, two man umpiring crew.

Suicide squeeze is on, R3 breaks for home, bunt is down the 1B line, PU is watching for the play at the plate and the foul ball. Pitcher comes across pick up the ball, has no play at home so turns and goes to first for the force out which the BU has got. While all this is going on, R2 at second takes off for third and about 2/3 of the way there, cut across the diamond to the 3B line and is safe at home before our 2nd baseman can return the throw to home. Our coach is going crazy, we make the proper appeal for R2 missing third base, and neither umpire saw what had happened.

I was guessing that the plate umpire should have this call since the BU has his back to play and is getting into a position for the call at first. Would that be correct? Personally, I just think that both umpires got caught up in the play and forgot about the runner at second.

Any comments?
