<P> Beginning in 1969, MLB split into four divisions, and the winners of each competed in the League Championship Series, with the winners advancing to the World Series . When a multi-tier playoff system was implemented in 1995, the LCS remained the series that determined the pennant - winner . The longest streak of consecutive LCS appearances belongs to the Atlanta Braves with 8 in a row from 1991 to 1999 (not counting 1994, when there were no playoffs), while the second - longest belongs to the Oakland Athletics with 5 in a row from 1971 to 1975 . </P> <P> Further expansion of the postseason began in 1995, with eight teams entering the playoffs each year (further expanded to ten teams in 2012). In this era, the Braves entered the postseason 14 consecutive years from 1991 to 2005 (again not counting 1994), while the Yankees had a streak of 13 appearances from 1995 to 2007 . However, all other postseason appearance streaks of 5 years or more predate the expanded - postseason era and are mentioned above, except for 5 - year runs by the Cleveland Indians (1995--1999), the Philadelphia Phillies (2007--2011), and the St. Louis Cardinals (2011--2015). </P> <Table> <Tr> <Th> Length </Th> <Th> Team </Th> <Th> Seasons </Th> </Tr> <Tr> <Td> 5 </Td> <Td> New York Yankees </Td> <Td> 1949--1953 </Td> </Tr> <Tr> <Td> </Td> <Td> New York Yankees </Td> <Td> 1936--1939 </Td> </Tr> <Tr> <Td> </Td> <Td> Oakland Athletics </Td> <Td> 1972--1974 </Td> </Tr> <Tr> <Td> </Td> <Td> New York Yankees </Td> <Td> 1998--2000 </Td> </Tr> <Tr> <Td> </Td> <Td> Chicago Cubs </Td> <Td> 1907--1908 </Td> </Tr> <Tr> <Td> </Td> <Td> Philadelphia Athletics </Td> <Td> 1910--1911 </Td> </Tr> <Tr> <Td> </Td> <Td> Boston Red Sox </Td> <Td> 1915--1916 </Td> </Tr> <Tr> <Td> </Td> <Td> New York Giants </Td> <Td> 1921--1922 </Td> </Tr> <Tr> <Td> </Td> <Td> New York Yankees </Td> <Td> 1927--1928 </Td> </Tr> <Tr> <Td> </Td> <Td> Philadelphia Athletics </Td> <Td> 1929--1930 </Td> </Tr> <Tr> <Td> </Td> <Td> New York Yankees </Td> <Td> 1961--1962 </Td> </Tr> <Tr> <Td> </Td> <Td> Cincinnati Reds </Td> <Td> 1975--1976 </Td> </Tr> <Tr> <Td> </Td> <Td> New York Yankees </Td> <Td> 1977--1978 </Td> </Tr> <Tr> <Td> </Td> <Td> Toronto Blue Jays </Td> <Td> 1992--1993 </Td> </Tr> </Table> <Tr> <Th> Length </Th> <Th> Team </Th> <Th> Seasons </Th> </Tr>
