The 2nd (and 3rd) tiebreakers are complicated enough. In the event of a 3 way tie (entirely possible), I think MLB will require some time on a Cray Supercomputer to figure it all out.
Near as I can tell, virtually all the tiebreakers on several levels are within a game of each other, meaning there are too many permutations to even try and figure out.
Bottom line, the Red Sox control their own destiny.
