Star Catcher made most of the running to cap a lucrative weekend for jockey Frankie Dettori and trainer John Gosden in the Qatar Prix Vermeille at ParisLongchamp.
The duo struck with Logician in the St Leger at Doncaster on Saturday – and victory on Star Catcher gave Dettori a 16th Group One triumph of the year, equalling his previous best tally in 2001.
Star Catcher, carrying the colours of Anthony Oppenheimer, had already contributed by winning the Irish Oaks and she produced another top-class performance.
Dettori had her to the fore from her rail draw, while stablemate Anapurna, the Epsom Oaks scorer, got a tardy start and could never get competitive.
Dictating affairs throughout, Dettori upped the tempo some way out and the 6-5 favourite galloped on strongly to score from two outsiders, Musis Amica (33-1) and Ligne D’Or (50-1).
“She’s a very good filly. She stays well, she doesn’t mind being in front and the ground was slick today and she likes it. I couldn’t fault her. She didn’t put a foot wrong,” Dettori told Sky Sports Racing.
“She was in the stalls for a while, but once she got to the front she was full of enthusiasm. She travelled strong. We went a decent gallop and she kept it up.”
Gosden said: “It was the plan to go forward, if no one wanted to lead we were going to go there, but she got left and Anapurna got left, got pinned in and didn’t get out until it was too late.
“But Frankie got forward and controlled the race and he is a bit of genius when he does that, he rides this course very well.
“She’s a brave filly, as she showed in Ireland – when they come to her she goes again and that’s what she did.
“We said after the Irish Oaks we would come here, that was always the plan. I’ll talk to Mr (Anthony) Oppenheimer, there are the options obviously of Ascot (Fillies And Mares Stakes on Champions Day) and Santa Anita (Breeders’ Cup), but it’s hard to do both, they’re quite close.”
He added: “I think she goes on most ground and is probably one of those nice fillies that could stay in training next year – Mr Oppenheimer enjoys his racing.”
