Advertise became the first British-trained winner of the Group One Keeneland Phoenix Stakes in over 20 years with a workmanlike victory at the Curragh.
Martyn Meade's colt was the 11-10 favourite in the hands of Frankie Dettori, with three of his four rivals trained by Aidan O'Brien, who had saddled a staggering 16 winners of the race in the last 20 years.
Advertise had finished marginally ahead of the reopposing Sergei Prokofiev when they came home second and third in the Coventry Stakes at Royal Ascot in June, since which Meade's charge had claimed an impressive victory in the July Stakes at Newmarket.
The Irish Rover adopted a pacesetting role, with Advertise always in his slipstream.
With Sergei Prokofiev failing to fire, The Irish Rover and Advertise settled down to fight it out and were joined by So Perfect racing inside the last of six furlongs.
There was little to split the trio as they raced for the line, but Advertise stuck his neck out to score by half a length, with So Perfect beating The Irish Rover to the runner-up spot.
Advertise is the first British raider to claim the Phoenix Stakes since Mark Johnston's Princely Heir in 1997.
