 The format has also been widely used in minor league baseball on all levels.In the Original Six era of the National Hockey League (1942-1967), the circuit adopted a Shaughnessy playoff system (first place "vs." third place and second place "vs." fourth place) in which the paired teams played in a best-four-of-seven-games series with the winners advancing to the Stanley Cup championship round.A Shaughnessy-style format is used in today's NHL in an entirely different context—since 2016, the All-Star Game has been contested as a four-team knockout tournament, with each team drawn exclusively from one of the league's four divisions.
