The 1976 Major League Baseball season was the last season of the expansion era until 1993 in which the American League and the National League had the same number of teams. The season ended with the Cincinnati Reds taking the World Series Championship for the second consecutive season by sweeping the New York Yankees in four games; they are the only team to go undefeated in the postseason since the advent of the divisional era in 1969. It would be the Reds' last title until Lou Piniella guided the club in 1990, and the second time that the Yankees were swept in World Series history. The only team to do it before was the 1963 Los Angeles Dodgers.
