Iridessa (Ruler Of The World) winning a maiden at Killarney

Iridessa is 4-length debut winner for Ruler Of The World

The Joseph O’Brien-trained Iridessa (2f Ruler Of The World-Senta’s Dream, by Danehill) made a winning debut on Tuesday night in the style of an outstanding filly.

The first-crop Ruler Of The World filly took on the colts on her first start at Killarney and powered clear of Magician’s highly-regarded son Cardini (2c Magician-Perfect Step, by Iffraaj) to win by four lengths.

“Joseph gave me the impression that he liked Iridessa and I would be inclined to agree! I haven't ridden many easier winners. She's really nice,” said winning rider Seamie Heffernan.

The winner races in the colours of her joint-breeder, Annemarie O’Brien, and the Racing Post predict a bright future for her.

Its analysis stated: “IRIDESSA certainly impressed here. Held up off the pace initially, she closed up nicely to move alongside the favourite over a furlong out, and the further the better she looked, quickening away for a convincing success.

“The way she went clear from a couple of horses with definite ability would put this down as a smart display. She doesn't have any fancy entries, but that is something that may change.”
