another running lane decision

[btdt]

During state playoffs last spring. R3, 2 out, ground ball to F-6 which F-6 fumbles around a bit and then makes a bad throw to first which pulls F-3 off the bag toward the plate.

Of course there is a collision and I have the runner safe.

Plate umpire calls time and call B/R out/interference for being out of running lane. Run does not count.

I did not agree but it was U-1 call.

My interpretation of the rule is for throws coming from behind the runner, not errant throws from F-6.

The call had an effect on who went to the state finals as the runner from third scored, but interference negated that run.
