Great Britain completed a clean sweep in their five-match series against the United States with a convincing 4-0 victory in San Diego.
Ashleigh Ball, Sarah Thomas, Vikki Bunce and Alex Danson all scored in a one-sided encounter on Sunday.
The teams met five times in eight days, with rain postponing one match.
"The US were tenacious in the first half and made it a very competitive game for us," said Great Britain head coach Danny Kerry.
"It was vital to score the early goal in the second half and from there we took control of the game and scored four good goals."
Crista Cullen, who made her 150th appearance for Great Britain and England combined, added: "Today was a great way to finish off our tour.
"We've dominated the series and it's been great to score so many quality open play goals."
