It’s a coin flip
No, I’m not talking about the Tigers playoff chances – which probably aren’t that good right now anyways. But in the event of a tie and a need for a one game playoff, the homefield was determined for those games if necessary.
If the Tigers and Yankees tie, Detroit heads to New York. If Detroit and the Seattle Mariners tie, the game will be played at Comerica Park. And finally, if the Mariners and Yankees tie, we don’t really care. But that will be in New York.
