Mallory Swanson scored a pair of goals just moments apart in the first half and the United States opened the Olympics with a 3-0 victory Thursday night over Zambia, giving new coach Emma Hayes a win in her first major tournament with the team.
Trinity Rodman also scored for the United States, which is looking to add a record fifth gold medal to its Olympic collection.
Zambia was hurt in the 33rd minute when Pauline Zulu was sent off with a red card and the team was limited to 10 players the rest of the way.
