But the Americans vowed to regain control of the tournament. Defender Kelley O'Hara said the United States needed to be “ruthless” against New Zealand.
And ruthless they were.
Rose Lavelle scored off a well-placed pass from Tobin Heath in the ninth minute to give the United States an early lead — and the team's first goal of the Olympics. Despite the lack of goals, the Americans dominated the half, unlike their out-of-sorts start against the Swedes.
Lindsey Horan scored with a header in the final moments of the half to put the United States up 2-0 at the break. It was Horan's 23rd international goal and it came on her milestone 100th appearance for the national team.
It could have been worse for New Zealand but the United States had four disallowed goals, all for offside, in the first half.
An own-goal by Abby Erceg extended the U.S. lead to 3-0 in the 64th. New Zealand avoided the shutout with Betsy Hassett's goal in the 72nd.
Christen Press, who came in as a second-half substitute, scored from the center of the box in the 80th off a feed from Julie Ertz, before Alex Morgan scored in the final minutes of regulation. Another New Zealand own-goal closed out the game in stoppage time.
U.S. coach Vlatko Andonovski made five changes to the starting lineup he used against Sweden, giving Carli Lloyd the start over Morgan, Megan Rapinoe for Press, Ertz for Sam Mewis, Emily Sonnett for O'Hara, and Tierna Davidson for captain Becky Sauerbrunn.
