The Ballydoyle combination enjoyed a fabulous Chester May meeting, winning all five big races, and after Amelia Earhart announced herself as Oaks favourite on the Roodee, O’Brien could have himself another Epsom contender after Cameo obliged backers in style at odds of 100-30.

With Charlie Appleby’s 11-8 favourite Romantic Symphony bitterly disappointing and failing to get involved, Cameo was able to track stablemate Bloom (Tom Marquand) into the straight before asserting over Andrew Balding’s running-on Prizeland late in the piece for a four-and-three-quarter-lengths victory.

The winner was made 12-1 from 40s by Oaks sponsors Betfred, while Paddy Power went slightly shorter for the Irish equivalent at 10-1.

O’Brien was not at Lingfield, but stable representative Chris Armstrong was watching on at Naas, from where he said after Ballydoyle had struck in the opener on that card: “She was very impressive. Obviously Tom’s filly suited going along in front and then Cameo got a lovely trail into it.

“In fairness to her, when Ryan asked her to knuckle down she went away. Wayne (Lordan) rode her the first day at the Curragh and felt going up in trip and better ground would suit. Those were the two factors she got today and in fairness she was very impressive.

“She is a lovely big, strong, imposing filly and she is bang in the Oaks mix now.” 

Moore was suitably pleased with his mount, and added: “Today was the first time I’ve ridden her. She’s a scopey filly, and handled the track well and did everything right,

“She picked up well from a long way out and kept going. She is a filly that will get better as the year progresses.

“She is a filly that will keep improving and you never know where they can end up, but I love everything she did today and would say she will get better.”
