James Doyle looks set to team up with Fair Eva for the first time in the Qipco 1000 Guineas.
Trainer Roger Charlton is a big fan of the jockey, who has recently returned from a spell in Australia riding for his principal employers Godolphin.
Doyle also won on the Charlton-trained Time Chaser, a sister to Time Test, in the Khalid Abdullah silks at Kempton on Monday.
Fair Eva, a Group Three-winning daughter of Frankel, is as low as 8-1 for the Fillies' Classic, behind only Aidan O'Brien's favourite Rhododendron.
"I'm very pleased with her and I'm satisfied she will stay a mile well," Charlton told At The Races.
"It would appear the Frankels definitely are training on as they're running very well.
"For a chestnut filly she has a very good temperament and, if anything, it is a job to get the weight off her rather than put it on her.
"I think she has an excellent chance of finishing in the first four as she's already a Group Three winner and Group Two-placed – she justifies her place.
"I'm not going to say she'll win the Guineas, because that would be stupid to say, but she's where we want her to be but it's a tough old race, as Classics should be.
"It's great to have James back. He rode a winner for me at Kempton on Monday and I hope that he will be riding Fair Eva for Juddmonte Farms in the Guineas."
