On 30 July 1930, Uruguay defeated Argentina 4-2 in the first World Cup Final before a standing-room-only crowd of over 100,000 at Montevideo's Estadio Centenario.
As previously mentioned, FIFA chose Uruguay as the host country because its national team were reigning world champions, having taken the gold medal at the 1928 Summer Olympics in Amsterdam. Argentina had claimed the silver, after playing Uruguay to a 1-1 draw on 10 June 1928, then falling 2-1 in the replay three days later. So the two sides were very familiar with one another leading up to the 1930 World Cup.
Uruguay scored first in the Final, with a 12th-minute goal from striker Pablo Dorado, who shot the ball through the legs of Argentinian keeper Juan Botasso. Argentina rallied, however, and took a 2-1 lead into halftime with goals from right forward Carlos Peucelle (20') and center forward Guillermo Stábile (37'). Stábile's goal was his eighth of the tournament, making him the top scorer.
The second half, though, belonged to the home side. Inside-left forward Pedro Cea scored the equalizer in the 57th minute, then outside-left forward Santos Iriarte netted the eventual match-winner in the 68th minute. Center forward Héctor Castro added another for good measure in the 89th minute, completing Uruguay's victory.
