Runner Interference on IFF Rule

[thumpferee]

What ever happened to Delayed Dead Ball?

It is a Delayed Dead Ball on an Obstruction play, 7.06 (b), why not on Interference?

IMO, it seems to be a disadvantage to the defense under such a rule.

Example: Same situation, but after the interference, the 1st baseman dives and catches the foul ball while his foot is touching the base to get R1 at first on a force play.

By rule, the runner is out and B1 gets to bat again?

Or, the ball lands fair (which in this case is an IFF) and is not an infield fly, the 1st baseman picks the ball up and touches runner and 1st base, double play. Under rule, only the runner is out and B1 gets 1st?

WOW!
