National Association of Professional Baseball
The Minor League (also known as the National Association of Professional Baseball Leagues) was established on September 5, 1901 from a meeting of Minor League executives at the Leland Hotel in Chicago. The association started out with 14 leagues and 96 clubs during its first season in 1902, under the leadership of then President Patrick T. Powers. After several years of effective leadership, Powers left office in 1909, after catalyzing the association’s expansion to 35 leagues and 246 clubs.
During its centennial season celebration in 2001, Minor League hit a milestone: its 100th season collectively attracted more than 28 million fans, the second highest in its history. This number was only surpassed in 2003 after having reached the 39 million mark in fans attendance.
