Since then, Pro D2 uses a six-team playoff with the winner earning automatic promotion to the Top 14 and the runner-up entering a playoff with the 13th-place team in Top 14 for the final place in the next season's Top 14. A nearly identical format, with the only difference being that the knockout stage followed a full home-and-away league season, was used by the second level of France's rugby union system, Pro D2, through the 2016–17 season. The League 1 playoff does not involve the top four teams the team that tops the table after the Super 8s phase, which follows a single round-robin phase involving all league teams, is crowned champion and receives automatic promotion to the second-tier Championship, while the next four teams contest a knockout playoff for the second promotion place. Variations of the Shaughnessy system also exist, such as in the promotion playoffs held by League 1 of the British rugby league. When a playoff of this type involves the top four teams, it is sometimes known as the Shaughnessy playoff system, after Frank Shaughnessy, who first developed it for the International League of minor league baseball. In most tennis tournaments, the players are seeded against each other, and the winner of each match continues to the next round, all the way to the final. Single-elimination tournaments are often used in individual sports like tennis. A single-elimination ('knockout') playoff pits the participants in one-game matches, with the loser being dropped from the competition.
