Samantha Murray settled for fifth in her first competition since winning Olympic modern pentathlon silver.
Murray had looked well placed for a medal at the modern pentathlon World Cup in Rio de Janeiro after entering the run/shoot on the top of the leader board.
But her lead was whittled away by Margaux Isaksen, the USA’s world junior champion, on the second shoot and the American went on to take gold.
Olympic champion Laura Asadauskaite from Lithuania climbed from seventh to take silver while Hungary's Zsofia Foldhazi completed the podium.
Murray, who said ahead of the run/shoot that she was targeting a top-ten finish on her return to action after London 2012, dropped out of contention for the medals but was able to make sure of fifth.
British team-mates Kate French came home 14th with Katy Burke 28th and world champion Mhairi Spence 33rd.
Great Britain's Joe Evans and Nick Woodbridge will contest Saturday's men’s final. Evans is hoping to follow his success on his World Cup debut in California a month ago, when he won the bronze medal.
