The United States returned to winning ways in emphatic fashion to kick-start their bid for Olympic glory, while Barbra Banda tied a Games record with a second successive hat-trick for Zambia.
Sweden had sensationally put an end to USA’s 44-match unbeaten streak at the start of the women’s tournament, with Megan Rapinoe admitting the beaten world champions had “played a bit tight” in a 3-0 defeat.
However, Vlatko Andonovski’s side responded impressively to that setback on Saturday, thrashing New Zealand 6-1 in Saitama, in the process registering their largest margin of victory in an Olympics fixture.
Rose Lavelle and Lindsey Horan gave USA a 2-0 half-time lead, the latter on target to mark her 100th cap. Further efforts from Christen Press and Alex Morgan added to the score after the break, while they were helped out by their opponents scoring two own goals.
It is the Swedes who sit on top of the table, though, as a strong second-half performance sealed a 4-2 triumph against Australia.
