Major League Baseball

The Daddy of all Professional Sports Leagues, the National Professional Baseball Players Association (more commonly known as the National League) can trace its’ roots to the Cincinnati Red Stockings, the first openly all-Professional sports team in the world. The Cincinnati Red Stockings incuded among the “First Boys of Summer” (that first ever Professional Team) an Irishman, Andy Leonard, born in Co. Cavan, who left Ireland as a baby during the famine. In all there have been 48 Irish-born Major League Baseball Players from 1869 to the present day. The American League was formed in 1901 and since 1903 has played for the “World Series” with the National League. The two leagues merged as Major League Baseball in 2001 although kept their National League and American League names and separate identities, with the two Champions still playing for the World Series.
