Aidan O'Brien and his son, Joseph, were quickly in the winner's enclosure through what looks a Classic-bound filly in Moth (11-8 favourite).
An exquisitely-bred and well-built daughter of Galileo, Moth had been made favourite in both her late-season starts last year, looking a little inexperienced to get off the mark, but holds entries in the Irish 1000 Guineas and Investec Oaks.
Moth travelled in behind the leaders in the Cancer Clinic Research Trust European Breeders Fund Fillies Maiden but, when switched wide for her run, her acceleration was dramatic and impressive as she galloped clear.
"She did it well. We thought she was nice last year but she got beat a few times," said Aidan O'Brien.
"Obviously I was giving the wrong instructions and instead of making use of her she should have been held up.
"She's able to change gears. It was a slow run race and she came from behind which I imagine wouldn't have suited. She quickened up well.
"She could go for a trial or head straight to Newmarket for the Guineas. It depends on what happens."
O'Brien also reported his colts on course for the 2,000 Guineas at Newmarket.
"The wheels are still on," he said.
"Mars is still going that way and I'm very happy with Cristoforo Colombo. We also have George Vancouver and Pedro The Great and they are all still standing so far."
