1930 World Cup final disputed over match ball

The 1930 World Cup final between Argentina and Uruguay was preceded by a dispute over which match ball to use, with Argentina favoring the Tiento and Uruguay the T-Model.

Referee John Langenus resolved the dispute by having both balls used: Argentina's Tiento for the first half and Uruguay's T-Model for the second, decided by a coin toss.

Argentina led 2-1 at halftime using its preferred Tiento, but Uruguay scored three unanswered goals in the second half with its T-Model to win 4-2.

Héctor Castro scored Uruguay's decisive 89th-minute goal, sealing their victory in the first World Cup final.
