Shaughnessy playoff system
The Shaughnessy playoff system is a method of determining the champion of a sports league that is not in a divisional alignment.
The system involves the participation of the top four teams in the league standings in a single elimination tournament to determine the championship. The first round of the playoffs could involve the pairing of the first- and fourth-place teams in one contest (whether it be a single game or a series of games) and the second- and third-place teams in the other, or the first- and third-place teams in one semifinal round and the second- and fourth-place teams in the other – either is considered a variant of the Shaughnessy system. In either case, the semifinal winners would then compete for the league championship.
