National Baseball League of Great Britain and Ireland

Baseball is a minor sport in the United Kingdom.

In 1890 the international version of the game was introduced to the United Kingdom in Derby by Francis Ley, a Derby man who had 'discovered' the game on a trip to the United States, and Albert Goodwill Spalding, an American former star player and sporting goods businessman who saw opportunities to expand his business across the Atlantic. Aston Villa, now known exclusively as a football club, won the only professional baseball championship in 1890. The competition was hindered by poor weather and disappointing crowds and made a loss to its investors. One of the first baseball clubs was the Derby County Baseball Club who lead the first championship after the National Baseball League of Great Britain and Ireland was established in 1890. However, pressure from other teams in the league over the number of American players on the Derby team and low attendances forced Derby to resign before the end of the season, though the baseball club itself lasted until 1898. The so-called Baseball Ground continued to be used under that name as the home of football's Derby County F.C. for over a century, from 1895 to 1997.

Baseball's peak popularity in Britain was in the years immediately preceding World War II. Baseball teams shared grounds with football clubs and the game was run at a professional standard with up to 10,000 spectators per game.

One milestone of baseball in the United Kingdom was the 1938 victory of Great Britain over the United States in the 1938 Amateur World Series, considered the first World Cup of Baseball.

Today, there are no more than 40 baseball teams, and 875 adult and Junior (Under 18) players ranging geographically from London to Liverpool, Bristol to Edinburgh. The Junior Great British National Team consists of 15 players which recently competed in the European championships.
