Casual Conquest displayed a brilliant turn of foot to land the Derrinstown Stud Derby Trial for the Dermot Weld stable.
Pat Smullen looked to be in trouble at the back of the five-runner field as the odds-on Washington Irving was sent up to challenge for the lead coming into the straight.
But the picture changed dramatically as Casual Conquest (13-2), making his seasonal debut, swept past his rivals and burst clear to record an impressive six-length victory in the Group Two feature.
The winner is not entered in the Epsom Derby and is more likely to go for the French version next.
Carribean Sunset put another one on the board for Weld and Smullen when staying on really well to secure the Derrinstown Stud 1000 Guineas Trial.
The 9-2 shot made smooth progress to lead over a furlong out and then showed a willing attitude to repel her pursuers.
John Oxx's highly-regarded Katiyra went off the 5-4 favourite and ran well to claim a half-length second on her first start for 266 days, and is bound for the Epsom Oaks.
The Group Three Amethyst Stakes fell to Ferneley (8-1), who led all the way under Willie Supple and quickened nicely in the straight before easily holding off Lord Admiral by two lengths.
Rory Cleary was lucky to walk away unscathed after a nasty incident in the final furlong of the Irish Stallion Farms EBF Auction Maiden.
His mount, the debutant Barack, was just being tackled for the lead by Duaisbhanna when he crashed through the running rail.
Cleary was soon on his feet and the Jim Bolger-trained Duaisbhanna (4-1) went on to win by three and a half lengths under Kevin Manning.
Tony Martin and Ruby Walsh teamed up to take the big race at Killarney, the Murphys Irish Stout Handicap Hurdle, with Northern Alliance.
