Diego Costa looked plenty fit for the World Cup, using a burst of speed on his injured hamstring to draw an early penalty and playing into the 74th minute Saturday to help Spain beat El Salvador 2-0 in a final tuneup before departing for Brazil.

David Villa scored his 57th and 58th international goals amid numerous near-misses for the reigning world champs, who begin the defense of their title Friday against the Netherlands in a rematch of the 2010 World Cup final in South Africa.

Facing an overmatched El Salvador squad being rebuilt after a match-fixing scandal, Spain had but one last question to answer before boarding the plane Sunday for South America: the fitness of Atletico Madrid striker Costa, who has been nursing a strained right hamstring that limited him to nine minutes in the Champions League final two weeks ago. Costa did not play in Spain's subsequent friendly against Bolivia.
