What if the head-to-head tiebreaker in a three-way tie looks at the cumulative record of one team against the other two teams?
The Red Sox are 9-8 against the Blue Jays and Mariners, the Blue Jays 9-8 against the Red Sox and Mariners, and the Mariners 6-8 against the Red Sox and Blue Jays.
Under that scenario, the Blue Jays and Red Sox would secure postseason slots and the Mariners would be left out in the cold again.
