Daley and Brick improved again at the Florida event
Great Britain diving pair Tom Daley and Max Brick won silver in the 10m synchronised event in Fort Lauderdale.
The duo were leading the competition after four dives but were finally overhauled by Americans David Boudia and Thomas Finchum.
But they finished comfortably ahead of Canadian pair Reuben Ross and Riley McCormick with a score of 423.48.
Daley, 14, teamed up with Brick in April after splitting from Beijing Olympics partner Blake Aldridge.
After scoring well through the rounds, an untidy fifth dive, a back two-and-a-half somersault one and a half twist pike, allowed their American rivals to steal a lead they never surrendered.
But the Britons will be pleased with a score that was a 20-point improvement on their debut performance at the Fina World Series in Sheffield.
Daley and Aldridge scored 408.48 in finishing eighth in the Olympic final.
