England's Laura Massaro was beaten in straight games in the World Open final by world number one Nicol David.
The Preston-based 29-year-old managed to force the Malaysian into long rallies and led 7-5 in the second game.
But David, also 29, completed a 11-6 11-8 11-6 in Grand Cayman for her seventh world title - and a fifth in succession.
"I'm proud to make the final but a bit disappointed I couldn't close out any of the games," said third seed Massaro.
"Congratulations to Nicol on another title. You have to work really hard to beat her; she doesn't lose very often.
"We're all working to get closer, but she steps up to the challenge to."
Great Yarmouth-born Massaro, playing in her first World Open final, added: "I've had a great tournament and a great experience here."
David said: "Laura played so well; she was pushing me on every point. I just couldn't relax at any time; she played a brilliant match today.
"I had to step up another gear to win. I just wanted to win so much."
