Baseball 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.
