The Grey Gatsby has scored an upset win in the Prix du Jockey Club at Chantilly for trainer Kevin Ryan and jockey Ryan Moore.

The French Derby has tended to be dominated by the home contingent, but British colt proved his success in the Dante at York was not a one-off as he quickened three lengths clear of Shamkiyr and the luckless favourite Prince Gibraltar.

The Grey Gatsby, who was sent off at nearly 20-1, was midfield early But Moore found an opening approaching the final furlong (200m) and his colt responded.

It was a first victory in the event for Moore, and a first major European Classic for North Yorkshire-based Ryan whose biggest prizes to date have largely come with two-year-olds.

"We always thought he was a good horse and after the Dante Ryan thought that the French Derby would be the right race for him," Ryan said.

"I don't think he got the credit he deserved after the Dante Stakes. Obviously it's great to win a French Classic.

"He will have a break now for a couple of weeks and then there would be the Juddmonte International to consider."

The trainer said he and owner Frank Gillespie would consider a late entry for the Prix de l'Arc de Triomphe.
