Carli Lloyd scored two goals to sandwich one from Julie Ertz, and the USA won 3-0 on Sunday, but Chilean keeper Christiane Endler was the star of the game.
Lloyd earned the start after coming off the bench in the opener, and in the 11th minute became the first player to score in six straight World Cup matches.
Julie Ertz scored in the 26th minute with a header off a corner kick from Davidson that Endler got her hands on but couldn't stop.
The New Jersey native and Rutgers product nearly had a hat-trick, just pulling her 81st-minute penalty kick wide left.

Lloyd scored a brace in Sunday's victory over Chile.
"A great performance. Both goals from her were fantastic". It was Ertz's first World Cup goal and came with her husband Zach Ertz, a tight end for the Philadelphia Eagles, looking on.
It may have received some criticism for the ruthless dismantling of Thailand in its opening game at the Women's World Cup but the USWNT was in no mood to go easy on Chile.
Lloyd has become the oldest player to score a couple of times in a Women's World Cup match, overtaking Brazilian Cristiane's record, set against Jamaica at this year's tournament. The third match against Sweden won't really matter, as long as the USA wins its first two games. She's been untested so far and has only had to defend a total of three shots in the first two games.

A draw with rivals Sweden in Le Havre on Thursday would be enough for this confident U.S. outfit to top the group on goal difference, following the Swedes' 5-1 win over Thailand earlier on Sunday. "We knew Endler was always going to keep them in the mix".
"It's haunting me right now", Lloyd said.
The 36-year-old captain, though, has struggled getting used to her role on this team heading into this tournament.
Only four players kept their place in the starting line-up from the Thailand demolition but Chile could do very little to stem the tide against a USWNT side intent on securing qualification for the knockout stages as quickly as possible.
The U.S. had a number of good chances to extend their lead in the second half, but Chile goalkeeper Christiane Endler made a number of good saves to keep the American's from adding more goals.
They have now won seven consecutive Women's World Cup matches, second only to the 10 achieved by Norway between 1995 and 1999.
