Hayley Turner is set to ride Marcus Tregoning's Cavaleiro in the Investec Derby at Epsom next Saturday.
While Turner plundered two Group Ones last term, landing the July Cup on Dream Ahead and the Nunthorpe on Margot Did, she has yet to line up in the premier Classic.
However, Turner will break new ground when she is given the leg up aboard the three year old next weekend.
Her commercial agent Jonathan Spence tweeted: "Hayley Turner will ride the Marcus Tregoning-trained Cavaleiro in the 2012 Investec Derby at Epsom Downs on 2 June."Alex Greaves is the only woman to have previously ridden in the Derby, finishing last on Portuguese Lil in 1996, but Turner's mount would appear to hold far stronger claims.
The son of Tregoning's Derby winner Sir Percy won a Chepstow maiden under the jockey before picking up a conditions event at Newbury.
He was third to Main Sequence on his comeback in the Lingfield Derby Trial.
"I just got a call from Mr Tregoning and he said I could ride the horse for Mr Guy Brooks in the Derby, so that was very kind of him," Turner told Racing UK.
"I won on him and then he won the Haynes, Hanson & Clark for Richard Mullen when I was off injured.
"He ran a good race around Lingfield on the all-weather, which probably wasn't ideal, and it's really nice to have a ride in the race.
"I think he's the sort of horse that will suit the course, he's quite a strong traveller and I think things didn't fall right for him at all in his Derby Trial and you'd want to put a line through that one.
"I suppose for any jockey it's nice to have a ride in the Derby, male or female, so obviously I'm thrilled.
"I'm chuffed with it. I don't hide my enthusiasm about the whole thing at all."
Sealed With A Winner
Buoyed by the news Turner gained an easy win at Goodwood in the Wright Joinery Company Handicap aboard Primaeval.
Racing off a mark 8lb lower on turf that he can on the all-weather, James Fanshawe's six-year-old travelled perfectly in behind the pace-setting Kakatosi and Bronze Prince.
When asked to go and win his race the gelding, owned by a syndicate including TV personalities Anthony McPartlin and Declan Donnelly, sprinted clear to win in a manner which suggests his days in handicaps may soon be coming to an end.
