moved to a new ground, Cathkin Park situated close to today's Govanhill Park. Having joined the newly formed Glasgow Football Association in 1883, the club was a founder member of the Scottish Football League in 1890. By then, Third Lanark had already won the Scottish Cup in 1889, having fallen at the final in 1876 and 1878. The name was changed to Third Lanark AC in 1903, when official links with the military were severed. Prior to World War I, the club won the Scottish League championship in 1903–04, as well as the Scottish Cup again in 1905 (then runners-up in 1906), and claimed the minor Glasgow Merchants Charity Cup in 1890, 1898, and 1900 and the Glasgow Cup in 1903, 1904 and 1909. In 1921, Third Lanark organised a tour of North America inviting several guest players to join them and thus being billed in some press reports and marketing as a 'Scotland XI'. Two years later the club (again with some guest players) made a tour over South America, playing a total of eight friendly matches in Buenos Aires and Montevideo, including a game against the Argentina national side on 24 June. They dropped out of the top division for the first time in 1925 and spent a period as a 'yo-yo club', with three relegations and three promotions in total over the next decade. As well as consolidating in Division One until the interruption of World War II, the club also reached another Scottish Cup Final in 1936, going down 1–0 to Rangers. After being relegated in 1953, Third Lanark beat Rangers 1–0 to lift the Glasgow Charity Cup in 1954, and captured the same trophy two years later against Partick Thistle, then returned to the top tier in 1957. After losing to Hearts in the 1959 Scottish League Cup Final, the last day of the 1960–61 season saw the club reach a historic landmark. Third Lanark beat Hibernian 6–1 at Cathkin Park to reach 100 goals for the season, and the win secured third place in Scotland's top division. The following season saw Thirds take part in European competition for the only time when the club faced Rouen of France home and away in the Anglo-Franco-Scottish Friendship Cup (Rouen won 4–0 at Cathkin on 7 November 1961 and 2–1 in France on 9 May 1962). Third Lanark won its final senior trophy, the Glasgow Cup, on
