Steve:
If the ball is coming from the left side of the infield and the ball takes F3 to the home side of the bag I wouldn't have a running lane violation. I might have a straight interference call or nothing. The running lane has nothing to do with it. It's an accepted pratice that the running lane is for plays coming from behind. I'm not sure why all the guys that have responded in this thread and the other one that you argued with Carl for so long feel that it's accepted practice and you're the lone voice thinking different.
It seems such a no brainer call I don't see why you feel the need to complicate it so. My impression was in the earlier thread you dug in simply because Carl said the opposite. This may be totally wrong but it appears to be your style.
