Frankie Dettori marks his last Derby day with win aboard Prosperous Voyage

Frankie Dettori secured a victory on his last Derby day as he steered Prosperous Voyage to success in the Princess Elizabeth Stakes.

The 52-year-old will retire at the end of the current campaign and after suffering disappointment in his final ride in the Derby, it looked unlikely he would get on the board when Ralph Beckett's filly exited the stalls untidily and left Dettori sat plum last.

However, the only Group One winner in the field showed her class at the business end of the race as the 6-4 favourite set about working her way into contention before knuckling down to see out the one-mile contest in game fashion.

Following on from his Group One double on Friday, it was a third victory of the weekend for Dettori on the Surrey Downs and it was fitting the victory came in the colours of Andrew Rosen, who along with co-owner Marc Chan, have been long-time supporters of the Italian.
