Collision and base tagging

[mbyron]

I was taught that a 'tag' is different depending on whether it's a force or tag play. For any play, fielder must have possession and voluntary release after tagging the runner. For a force play, the runner is out when the base is tagged, even if the fielder subsequently loses possession of the ball.

Technically, tagging 1B in advance of the runner is not a force play, but for purposes of this ruling you can treat it as one. In your situation if F3 has the ball securely the moment he steps on 1B, I've got BR out, run does not score, call it extra innings.

BTW, I agree with your non-call on interference/obstruction. F3 was not obstructing because he was making a play; BR did not interfere if the collision was not intentional.
