question on "interference"

[ChucktownBlue]

How can anyone award third on this play?

Pitch into dead ball territory... one base TOP.
or
Interference for offense not vacating space needed for defense to make a play... runner is out. (7.11)

Personally, if the ball was obviously going into DBT, I'd give one base. Have called similar sitch several times this past year... Ground ball to infield, wild throw to first which is going into dugout, hits bucket which coach is sitting on in front of dugout opening. Two bases time of pitch. No arguments.

Don't award offense for the offense making a mistake.
