FERREIRAS, Portugal — A spectacular late goal from substitute Natasha Kai gave the United States a 1-0 win over Iceland today and sent the defending champion into the final of the Algarve Cup.

In the last minute of the game Kai, a Kahuku and University of Hawai'i alum, received a cross from Christie Rampone on her chest, flicked the ball over a defender and fired a left-foot volley into the corner from the edge of the penalty area.

The Americans have six points after two wins from two in Group B and still have to play against Norway in the invitational women's tournament in southern Portugal.

In the group's other game, Denmark moved onto three points after beating Norway 2-0.

Though both Iceland and Denmark could catch the United States on points in Monday's last round, the group winner is decided on the result of head-to-head games. The United States beat Denmark 2-0 on Wednesday.

The Americans, who have won the tournament six times in the past eight years, will meet the winner of Group A in the March 11 championship game.

Monday's game between Germany and Sweden will settle top spot in that group after they both won Friday.

Kerstin Garefrekes scored twice and Kim Kulig added another as Germany ensured its perfect record with a 3-0 victory over China. Germany won the title in 2006 but has been out of the top three finishers in the past two tournaments.

The Germans lead Group A with six points, two ahead of Sweden which edged Finland 1-0 with a goal from midfielder Nilla Fischer.

The United States featured three changes from the team that beat Denmark, including Amy Rodriguez in for Kai and Nicole Barnhart replacing Hope Solo in goal.

Iceland, which upset four-time Algarve champion Norway in its opening game, played with a compact defense that kept the Americans at bay in a mostly uneventful game.

"The best part (of the game) was the goal," U.S. coach Pia Sundhage said. "I'll try some fresh legs in the next game."

In Group C, which contains teams not competing for the title, Austria and Poland drew 1-1. Portugal was playing against Wales in a late game.
