SIGNORA Cabello narrowly prevailed in a blanket three-way finish to the Queen Mary Stakes at Royal Ascot.

A big-priced winner of a listed race at York last time out, the powerful Phoenix Thoroughbred organisation bought a three-quarter share into the filly.

Still in the care of John Quinn and ridden by Oisin Murphy, the daughter of Camacho was sent off at 25/1 on this occasion, and was never far from the pace.

Aidan O’Brien’s Gossamer Wings and the Clive Cox-trained Shades Of Blue were late challengers, but it was the northern raider who prevailed by a short-head and the same.

Wesley Ward’s favourite Chelsea Cloisters never threatened at any stage under Frankie Dettori.

Quinn said: "All she did, really, was improve. She was well on top at the line (at York) and since then she’s trained lovely. She’s very unassuming. She’s terribly, terribly tough. I’m really pleased."
