Saddler's Rock maintained the fine record of Irish challengers at this year's St Leger Festival with victory over Opinion Poll in the Doncaster Cup.
The three-year-old, ridden by Niall McCullagh, is trainer John Oxx's second winner of the week, after Alanza.
Favourite Opinion Poll and Frankie Dettori cruised into the lead a quarter of a mile out but Saddler's Rock swept to victory in the closing stages.
The Gold Cup at Royal Ascot next June should be the winner's 2012 target.
To keep Irish eyes smiling, the very smart two-year-old Requinto continued his good season with success in the Polypipe Flying Childers Stakes.
Dettori, who had better luck on the impressive Godolphin-owned juvenile Lyric Of Light in the May Hill Stakes, is looking forward to partnering another filly, Blue Bunting, in the St Leger.
The Italian said of the second favourite, a dual Classic winner: "I always like to ride her because she is going to be thereabouts, and she loves a scrap.
"A strong-run mile and six furlongs will be absolutely ideal for her."
