Running Lane?

[Macaroo]

R1 and R3, I stand in B, but that's neither here nor there.
First mistake was getting a rule book. Second was having a ten minute delay. I suspect that the discussion was defense claiming that BR avoided the tag by running more than three feet out of his baseline. If this was the case, PU should have nailed it right away (when BU asked for his help). The runner is allowed to step out of the running lane as long as he doesn't interfere with a throw to 1B, which isn't the case here. So, the only question is, was his "dodge" greater than three feet away from his line? I doubt it was, but I would have to actually see the play to know.

Two possible anwers here: "Sorry coach, runner stepped away, but within three feet, he's safe. Or, "Oh yeah, I guess he DID run more than three feet out of the baseline (ten minutes ago), and it says right here in the rule book we have to call him out. Thanks for the input coach." Sorry about the sarcasm, but this is a judgment call that should be ruled on right away, not a clinic topic during a game.
