The USA are back in the World Cup after missing the 2018 tournament and had to win against Iran, who were on three points going into the match after two last-minute goals against Wales in their second match.
Christian Pulisic scored while crashing headfirst into the goalkeeper in the 38th minute – he sprawled on the field and was lying in the goal for about three minutes as he received treatment from the US staff. He reentered the game but was replaced at the start of the second half.
"I always say it's us against the world," forward Tim Weah said. "No one believed the US could play good football."
Iran finished third with three points. The team has failed to advance in all six of its World Cup appearances.
There was heightened tension surrounding the match because of the strained relations between the United States and Iran's Islamic government. Iran had famously upset the US 2-1 in the 1998 tournament in France, eliminating the Americans.
