Ouija Board returned to her stunning best to win the Cathay Pacific Hong Kong Vase at Sha Tin. Kieren Fallon timed his run perfectly on Ed Dunlop's filly, whose triumph has increased the chances of her staying in training as a five-year-old.
Having been last at one stage, Fallon brought the four-year-old through the pack in the home straight.
Ouija Board beat Six Sense by two and three-quarter lengths with Best Gift a further three lengths away in third.
"I've ridden some seriously good fillies like Bosra Sham and Islington and on this evidence she must be right up there with them," said Fallon.
Dunlop praised the patience and faith of owner Lord Derby for allowing him to carry on with last year's dual Oaks winner after the opening months of her campaign were blighted by injury problems.
"She missed half the season but this has made it all worthwhile," he said.
"I have to thank my head lad and the vets who have treated her. Without their efforts this couldn't have happened."
