SAN DIEGO (AP) — Mallory Pugh scored a pair of second-half goals, and the U.S. women's national team opened the year with a 5-1 victory over Denmark on Sunday. Alex Morgan, Julie Ertz and Crystal Dunn also scored for the top-ranked United States. The match was the first for a year that will include qualifying for the 2019 Women's World Cup in France. The Americans are the defending champion of the sport's premier event. Denmark went up 1-0 in the 14th minute off Nadia Nadim's header. It was the 23rd international goal for Nadim, who played last season for the Portland Thorns in the National Women's Soccer League. Morgan equalized in the 17th minute with her 81st international goal, seventh on the team's all-time list. Ertz then scored in the 19th minute. While Ertz was playing for the U.S. women, husband Zach Ertz was playing for the Philadelphia Eagles in the NFC championship game.  Pugh put the Americans up 3-1 in the 47th minute, and then scored her second in the 65th. Dunn added a goal in the 81st minute.
