The 1977 Major League Baseball season saw the American League (AL) having its third expansion, as the Seattle Mariners and Toronto Blue Jays began play, with Seattle returning to the MLB fold after a seven-year absence when the Pilots relocated to Milwaukee to become the Brewers. However, the National League (NL) did not expand, remaining at 12 teams compared to the AL's 14, until the Colorado Rockies and Florida Marlins joined the NL in 1993.
The season ended with the New York Yankees winning their 21st World Series title (and first since 1962) over the Los Angeles Dodgers.
