One of baseball’s more obscure streaks has been broken, thanks to the Mets beating the Cubs in the National League Championship Series to advance to the World Series.Until this year, every Fall Cla sic had featured at least one of the 16 MLB franchises that existed at the time of the first World Series in 1903. But that won’t be true in 2015; the Mets, who joined the National League in 1962, will play either the Royals (1969) or the Blue Jays (1977). UPDATE: It will be the Royals after Kansas City’s dramatic clinching victory in the American League Championship Series. https://www.rangersedges.com/texas-rangers/delino-deshields-jerseyMORE: Top photos from the NLCS| Mets’ most memorable postseason momentsExpansion in MLB dates to 1961, when the American League added the Los Angeles Angels and the Washington Senators (the expansion Washington Senators replaced the existing Senators, who simultaneously moved to Minnesota and became the Twins). The NL first expanded by adding the Mets and Houston Colt .45s (now Astros) a year later.The Mets became the first expansion team to play in and win the World Series when they beat the Orioles (previously theSt. Louis Browns) in 1969. Other expansion teams to win the World Series are the Royals (1985), Blue Jays (1992, 1993), Marlins (1997, 2003), Diamondbacks (2001) and Angels (2002). The Rangers, Astros, Brewers, Padres, Rockiesand Rays all have played in the Fall Cla sic. The Mariners and Expos/Nationals have not.
