The 1977 Major League Baseball season. The American League (AL) had its third expansion as the Seattle Mariners and Toronto Blue Jays began play. 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.
I sincerely appreciate the research work, and the information being shared. It is important and interesting history.
