US survive Portugal scare to reach last 16 at Women's World Cup
The USA struggled to impose themselves against opponents ranked 21st in the world and appearing at their first World Cup, and Portugal almost won the game in injury time when substitute Ana Capeta hit the post.
Holding on for the draw means Vlatko Andonovski's side finish in second place in Group E.
The Netherlands go through as group winners after a 7-0 demolition of a Vietnam side who were beaten just 3-0 by the Americans in their first match at the tournament.
That means pre-tournament favourites the USA will move to Australia to play a last-16 tie on Sunday against the winners of Group G, in all likelihood Olympic silver medallists Sweden.
Right down to the wire.
