Bob J.,

BR out on abandonment. 8.4.2X

None of the rule codes provide any specific criteria for the umpire to use in judging at what point the runner has abandoned his effort to run the bases and loses his right to reassert his status as a runner.

The most complete treatment of the subject that I have found is in the JEA. In regards to harmbu's 2nd question, the JEA says in the discussion of 7.08(a)(2):

A batter-runner who inexplicably fails to return directly to 1st base after overrunning it shall not be called out before entering the dugout.

I realize that the JEA is specifically an OBR interpretation source, but I have not been able to find any FED-specific source that would contradict the criteria suggested by Evans, and I would be inclined to use his suggested criteria, even in a FED game.

I was taught that abandonment should be used as "a call of last resort", rather than an easy "unearned out" for the defense.

Is there a FED source on this that contradicts the JEA? At what point in time would you judge the runner was out for abandonment & what are the criteria you would use?
