MANAUS, Brazil (AP) -

They were less than 30 seconds away.
    
The Americans were about to romp into the round of 16 at the World Cup, about to walk off with their first come-from-behind win at soccer's showcase. About to advance with a game to spare. About to win consecutive World Cup games for the first time since 1930.
    
But they wilted in the Amazon heat and humidity.
    
Varela's goal on a diving header off Cristiano Ronaldo's cross on the game's last play gave Portugal a 2-2 tie Sunday on an exhausting night in the rainforest capital.
    
Now the Americans may need at least a point Thursday against Germany to advance to the knockout stage. They could advance with a loss, depending on the result of the Portugal-Ghana game that will be played simultaneously.
