full_context: Document 1: 1976 World Series: The 1976 World Series matched the defending champions Cincinnati Reds of the National League against the New York Yankees of the American League, with the Reds sweeping the Series to repeat, avenging their 1939 and 1961 World Series losses to the Yankees in the process. The 1976 Reds became—and remain – the only team to sweep an entire multi-tier postseason, one of the crowning achievements of the franchise's Big Red Machine era. The Reds are also the last National League team to win back-to-back World Series. It also marked the second time that the Yankees were swept in a World Series (the Los Angeles Dodgers were the first to sweep them in 1963).
Document 2: 1966 World Series: The 1966 World Series matched the American League (AL) champion Baltimore Orioles against the defending World Series champion and National League (NL) champion Los Angeles Dodgers, with the Orioles sweeping the Series in four games to capture their first championship in franchise history. It was also the last World Series played before Major League Baseball (MLB) introduced the Commissioner's Trophy the following year.

The game was played at Fenway Park in Boston, on October 2, 1978. The tie-breaker was necessitated after the Yankees and Red Sox finished the season tied for first place in the AL East with identical 99–63 records.

Document 5: Brooklyn Dodgers (NFL): The Brooklyn Dodgers were an American football team that played in the National Football League from 1930 to 1943, and in 1944 as the Brooklyn Tigers. The team played its home games at Ebbets Field of the baseball National League's team, the Brooklyn Dodgers. In 1945, because of financial difficulties and the increasing scarcity of major league-level players because of the war-time defense requirements at the height of World War II, the team was merged with the Boston Yanks and were known as the Yanks for that season. This old NFL franchise was not related to the earlier (second incarnation) American Football League II with a franchise that played as the Brooklyn Tigers for the first half of the 1936 season before moving to Rochester, New York and playing as the Rochester Tigers. Another NFL team that played in the Brooklyn borough was the Brooklyn Lions (which became the Brooklyn Horsemen after merging with a team from an earlier first incarnation AFL of the same name) in 1926. Later co-owner and partner Dan Topping (1912–1974), pulled the Tigers team out of the old NFL in 1946 and placed it in the newly established rival professional league – the All-America Football Conference, which shortly lasted until 1949 until several stronger teams from the AAFC merged with and entered a reorganized NFL in 1950. It lasted until 1970 with the NFL-AFL (third) merger following the establishment of the first "Super Bowl" inter-league national championship game three years before with the old NFL champions playing the victors of the latest rival fourth incarnation of the American Football League IV, formed in 1960 (now the American Football Conference (AFC).
