Red-hot favourite Fair Eva could only finish third as Queen Kindly claimed victory in the Sky Bet Lowther Stakes at York.
The Roger Charlton-trained Fair Eva had looked every inch a top-class prospect on her racecourse debut at Haydock and after following up with another impressive display in the Princess Margaret Stakes at Ascot, the daughter of Frankel was a prohibitively priced 4-11 market leader in this Group Two contest.
Queen Kindly - another daughter of the mighty Frankel and out of 2009 Lowther-winning mare Lady Of The Desert - had won two of her three previous starts for Richard Fahey, both at Catterick, and was a creditable third in the Albany Stakes at Royal Ascot in between.
Pat Smullen settled Fair Eva at the rear of the field for much of the six-furlong journey, with Jamie Spencer similarly patient aboard 9-2 chance Queen Kindly.
Fair Eva came with her effort on the wide outside, while Queen Kindly had to be brave go between horses to mount her challenge.
Aidan O'Brien's Duchess of Cambridge Stakes winner Roly Poly was also in with a chance as the big trio headed inside the final furlong almost in a line, but it was Queen Kindly who saw it out best to beat the Irish raider by three-quarters of a length, with Fair Eva the same distance away in third.
