So what warrants the one game playoff in baseball? Just a tie between two teams? I know in basketball and other sports, they use tiebreakers such as head-to-head to determine playoff scenarios. In other words, if the Mets and Brewers end up with the same record at the end of the year, is there automatically a one game playoff or are there other factors involved? Excuse my ignorance, but I've never had to worry about this stuff before.
