El Salvador completed a hat-trick this year when making all in the mile and a half Summer Twilight Nights Race to complete a double on the day for Aidan and Joseph O’Brien.

Successful on his previous two outings on the polytrack at Dundalk, the Galileo colt coped very well with the much different ground conditions here and dictated matters from the front.

The well-backed evens favourite Voleuse De Coeurs travelled well into the straight but last year’s Cesarewitch winner was unable to make any inroads into the two-length advantage held by the winner.

El Salvador (15/8) stayed on strongly inside the final furlong to record a two and a quarter lengths winning margin, with Chicago another five and a half lengths adrift in third.

The field was reduced to just four runners after Encrypted Message (lame) and Military Bowl (change in ground conditions) were both taken out.

Aidan O’Brien said, “That isn't his ground and he wants it better. There is a big engine in there and I'd say he is a fair horse. He kept picking up and picking up and he'll come back here for the Martin Molony Stakes (on June 21)."

The O’Brien’s earlier initiated their double with 2/7 chance Marchese Marconi in the mile and three furlongs maiden.
