KAZAN, Russia (AP) -- Diego Costa scored on a deflection to lead Spain to a 1-0 win over Iran on Wednesday at the World Cup.
Costa broke the deadlock in the 54th minute after being set up by Andres Iniesta. The powerful striker turned in the area and took a shot but the ball deflected off Ramin Rezeian before bouncing back onto Costa's knee and into the net.
Costa, who also scored two goals in the opening match, has three goals at this year's World Cup, trailing Cristiano Ronaldo by one. He also has nine goals in his last nine starts for Spain.
