Here’s something that may only be interesting to me:

A franchise named the Milwaukee Brewers is one of the American League’s 8 charter teams. Before the first season even began plans were being made to move the team, and after just one season it moves to St. Louis. Milwaukee would become a popular minor league city with a team also called the Brewers, before the Braves moved there from Boston in 1953. However after 13 seasons the Braves would move to Atlanta leaving Milwaukee without a team again. In 1969 the American League expanded adding the Kansas City Royals and Seattle Pilots. Seattle had many problems and was clearly not ready to host a Major League team so after just 1 season the team was on the move and it would end up in the same city that 68 years earlier lost a team after only 1 season.
 

Also, that original franchise is now known as the Baltimore Orioles.
