Missed base

[joemoore]

4.09 has an exception if fans rush the field and physically prevent a game winning run from scoring, the umpire awards the base.

There is also an exception for sliding bases, if the base is moved from it's normal location the runner is only required to touch the space originally marked by the base. (7.08c)

Suppose runner is obstructed and prevented from touching 2B. He continues to third. Play ends and umpire calls time to enforce the obstruction. During the dead ball he is prevented from returning to second base, correct? There has to be an exception.

I'm ignoring it, but if he was required to touch the base, then I'd tell the runner when I enforced the penalty. "Runner was prevented from touching 2B. Runner, go touch 2nd base and proceed to third."
