Major League Baseball

One of the many signs of spring is baseball's spring training, even though it wintry in much of the U.S. then. Even opening day games in April are often cold and even snowy. The "Boys of Summer" probably prefer days that are in that just-right Goldilocks zone that is late spring and early autumn.

The pandemic really hurt baseball as well as other sports in 2020 and although the games are on this year, the number of fans is still limited and teams still are still dealing with cases.

Major League Baseball (MLB) is a professional baseball organization and the oldest of the major professional sports leagues in the United States and Canada.

There are 30 teams in American Major League Baseball (MLB). They are divided up evenly between the American League (AL) and National League (NL) with 15 teams in each. Each of the leagues is divided into three divisions called the East, the Central, and the West.

The NL and AL were formed as separate legal entities in 1876 and 1901, respectively. Beginning in 1903, the two leagues cooperated but remained legally separate entities. In 2000 the leagues merged into a single organization led by the Commissioner of Baseball.

We are working our ways through all the teams' name origin stories. 

MLB also oversees Minor League Baseball, which comprises 256 teams affiliated with the major league clubs. I don't know if we'll get around to all those minor league teams - but some have very interesting name-origin stories.
