Costa Rica came from behind to stun Uruguay 3-1 Saturday at the World Cup, opening the tough Group D with a major upset.
Uruguay left star striker Luis Suarez on the bench but went ahead when Edinson Cavani scored a penalty in the 24th minute.
But the Central Americans fought back after the break and lone striker Joel Campbell slotted in a ball headed down by Celso Borges in the 54th to beat goalkeeper Fernando Muslera.
Oscar Duarte dived past the outstretched foot of Uruguay's Cristian Stuani to head in the winner for the underdogs, and substitute Marcos Urena added the third with six minutes left, catching out Muslera to slot the ball in from a tight angle.
Suarez is still recovering from knee surgery and never came off the bench.
