Multiple Obstructions

[MD Longhorn]

This came up a few years ago and was originally a softball play, and I posted it then - generating some lively discussion. It came up again while sitting under the Umpire Tree last week, so I thought I'd see if it generates any new thoughts this time around, and if the conclusion is different for either OBR or FED than it is in ASA or other softball codes...

No one on base, B hits the ball between the outfielders. As he's rounding first, F3 is standing on the bag. BU rules and signals obstruction, mentally noting that this runner would have gotten to third base without the obstruction.

B rounding 2nd, and the throw, heading from CF to a deep SS, is dropped by the SS. While rounding 2nd, he collides with an inattentive F4 watching the play. BU resignals the obstruction, and based on where the ball is and where the runner is, again decides that based on this OBS alone, he should get 3rd.

Runner slides safely into third base.

PU and BU discuss, and both had the same awards - but both feel that had NEITHER obstruction occured, AND the misplay at F6 happened as it did, this runner likely would have scored.

What do you do?
