In the 1978 Major League Baseball season, the New York Yankees defeated the Los Angeles Dodgers to win their second consecutive World Series, and 22nd overall, in a rematch of the prior season's Fall Classic. The Yankees overcame clubhouse turmoil, a mid-season managerial change, and a 14-game mid-July deficit in the American League East en route to the championship. All four teams that made the playoffs in 1977 returned for this postseason; none of the four returned to the postseason in 1979.
