Uruguay defeated Brazil 2-1. Brazil scored first through Friaça two minutes after half-time, but Juan Alberto Schiaffino equalised in the 66th minute and Alcides Ghiggia scored the winner with 11 minutes remaining.
The officially recorded attendance was 173,850 paid spectators, making it the highest number of paid spectators ever recorded for a football match. Estimates including those who entered without tickets place the actual figure as high as 220,000, possibly exceeded only by the 1923 FA Cup final.
Maracanazo is a Portuguese and Spanish word roughly translated as "The Maracanã Smash." It became synonymous with Uruguay's unexpected 2-1 victory over host nation Brazil at the Maracanã Stadium on the 16th of July 1950, which denied Brazil the World Cup title they had been publicly celebrating before the match.
Alcides Ghiggia scored the winning goal, driving a low shot from the right side of the field that goalkeeper Moacir Barbosa, who had anticipated a cross, dived too late to stop. The goal came with 11 minutes remaining in the match.
Brazil's white shirts with blue collars worn in the 1950 final were criticised by the country's sports federation as unpatriotic following the defeat.

Varela overrode coach Juan López's defensive strategy and told his teammates: "Juancito is a good man, but today, he is wrong. If we play defensively against Brazil, our fate will be no different from Spain or Sweden." He closed with the line: "Muchachos, los de afuera son de palo. Que comience la función" - roughly "Boys, outsiders are just stickdolls. Let the show begin."
