Chen was one of only two divers to score more than 80 points with a single dive â?? but she did it four times â?? to finish with a total of 407.25 points.

Meaghan Benfeito of Canada qualified second with 359.90 points and Brittany Broben of Australia was third, less than half a point behind with 359.55.
