Question: is baseball best of 7?
Answer: The winners of the ALCS and NLCS advance to the World Series, the best-of-seven-game playoff. Prior to the 2002 season, a home-field advantage (games 1, 2, 6, and 7) alternated every year between the leagues. ... The first team to win four games in the best-of-seven-game series becomes the Major League champion.
