Baseball has been around for what seems like forever. Major League Baseball, in particular, was formed in 1876 and is the oldest professional sports league in the US. The game has changed over the years, building a storied history.
Traditional MLB rivalries over the years feature some of the game’s most storied clubs facing off, including the Boston Red Sox vs. New York Yankees rivalry that goes back to Babe Ruth being sold, the bad blood between the Los Angeles Dodgers and San Francisco Giants, or the St. Louis Cardinals vs. Chicago Cubs.
With the introduction of MLB interleague play allowing American League teams to play National League teams each season, new heated rivalries have also formed over the years, each being nearly worth its own tv show. Before this, these rivalries were only possible if both teams made it to the World Series.
Whether during the MLB regular season or postseason, it is hard not to get excited for a series with these teams going head-to-head against one another for three or four games. You never know what you might see as the biggest MLB rivalries take to the diamond each season.
