Ireland crashed to a 5-0 defeat to the US in an international friendly in Portland, Oregon as Alex Morgan's first-half hat-trick proved she has not lost her scoring touch.
Morgan, who netted a game-winning Olympic semi-final goal last summer when the U.S. took gold, showed little rust as she wowed the Portland crowd.
"We've been waiting and itching to get out there on the field, I think (this) showed that we wanted to get out there and play," Morgan said afterwards.
"I just wanted to keep taking shots and they kept going my way."
Sydney Leroux completed the rout by scoring twice in the second half to give a perfect start to new coach Tom Sermanni's tenure.
