The English football club, Aston Villa, were the first British baseball champions winning the 1890 National League of Baseball of Great Britain. The 2020 National Champions were the London Mets. Other European countries have seen professional leagues; the most successful, other than the Dutch league, is the Italian league, founded in 1948. In 2004, Australia won a surprise silver medal at the Olympic Games. The Confédération Européene de Baseball (European Baseball Confederation), founded in 1953, organizes a number of competitions between clubs from different countries. Other competitions between national teams, such as the Baseball World Cup and the Olympic baseball tournament, were administered by the International Baseball Federation (IBAF) from its formation in 1938 until its 2013 merger with the International Softball Federation to create the current joint governing body for both sports, the World Baseball Softball Confederation (WBSC). Women's baseball is played on an organized amateur basis in numerous countries.
