Major League Baseball is a professional North American baseball league. It is also regarded as the world’s best professional baseball. Two leagues comprise the MLB: the American League, also known as AL, and the National League, also known as NL. At present, there are thirty MLB clubs, 29 from the United States, and the Toronto Blue Jays are the only ones coming from Canada.

In 1876 and 1901, both the NL and the AL were created. The two leagues cooperated from 1903 until 2000 when they united into the same association headed by the Baseball Commissioner but remained legal independent bodies.

Some MLB records can be seen as “unbreakable” due to either random events or the fact that they were established in the early decades of baseball when there were different rules.Others are caused by changes in the game over time which makes it impossible for the records to be broken.
