Interference? (Legion)

[JJ]

I went to ask.com and did a search for American Legion rules. They use the NCAA collision rule - that the fielder must have the ball to legally be in the basebath blocking the base.
If a collision occurs, the umpire must judge if it was avoidable or unavoidable, and if the runner was deliberately trying to dislodge the ball. If the collision was unavoidable, the umpire must judge if it was flagrant. Then he rules accordingly.
In the case posted, since the fielder did not have the ball when the contact occured, and the contact was not flagrant, it sounds like a "no call" UNLESS you judge it to be obstruction - IF the runner was safe at second and THEN the contact occured, and argument could be made that he was obstructed between second and third. Whole new can of worms!
