Goals from Catarina Macario, Sam Coffey and Lindsey Heaps delivered a convincing win for the Americans, who dominated the tie at Saint Paul, Minnesota.

China PR, preparing for the defence of their AFC Women's Asian Cup™ title, found themselves behind in the 28th minute with Macario bundling home a close-range finish after good work from Alyssa Thompson.

The USA doubled their tally seven minutes later with a brilliantly worked goal, which began when the gifted 17-year-old midfielder Lily Yohannes released Thompson down the right who crossed for Macario.

Macario played a short pass into Coffey, who swept home with aplomb.

Macario and Heaps both threatened to add to the USA tally with long-range shots that were just off target before half-time.

Heaps though bagged the USA's third in the 54th minute, nodding in past China PR goalkeeper Pan Hongyan to effectively seal the win.
