Gleneagles enhanced his reputation with a clear-cut victory in the Goffs Vincent O'Brien National Stakes at the Curragh.
Having already secured the Tyros Stakes at Leopardstown and the Futurity Stakes over this course and distance three weeks ago, Aidan O'Brien's Galileo colt was a warm order to strike at Group One level.
Settled last of the five runners as stable companion Toscanelli played the roll of pacemaker, Gleneagles (1-3 favourite) had to be bustled up to take closer order in the straight, but Joseph O'Brien got the required response.
The youngster showed a smart change of gear to run to the lead and was driven out to claim victory by a length and a half, with Mick Halford's Toscanini best of the rest.
The winning trainer said: "He has plenty of speed and is probably a Guineas horse.
"He quickens very well, and could go for the Dewhurst."
Gleneagles is 14-1 from 16-1 for the Qipco 2000 Guineas with RaceBets.
