Gossamer Seed gave her younger rivals a sound beating in the Canford Cliffs European Breeders Fund Athasi Stakes.
As the only four-year-old in the race, John Joseph Murphy's filly was conceding the best part of a stone to each of her four adversaries.
However, Shane Foley's mount relished the testing conditions and easily pulled clear running inside the last of the seven furlongs to register a four-and-three-quarter-length victory over market leader Bulbul.
Murphy's son, George, said: "This filly will probably go for another stakes race in a month and then she'll likely get a break. We'll try to make the most of any opportunities for her on soft ground."
Foley went on to complete a notable double as Ondeafears ran away with the Newbridge Credit Union Handicap.
The Mick Halford-trained 6-1 shot had finished second on her seasonal debut at Leopardstown last month and ultimately had no trouble going one place better.
Favourite Winning Impact was still right there a furlong down, but he had no answer when Ondeafears found an extra gear, winning the argument by three and a half lengths.
Jim Bolger's Move To Strike got off the mark at the second attempt with an impressive display in the Alfred Nobel European Breeders Fund Maiden at the Curragh.
The juvenile was sent off the heavily supported 4-6 favourite on the strength of his debut third at Leopardstown last month and it was clear from the halfway stage that he had each of six rivals in trouble.
Kevin Manning asked his mount to stretch clear passing the furlong marker and he did so in some style, quickening right away in the rain-softened ground to score by nine lengths.
Debutant Slope finished best of the rest, but was not in the same league as the runaway victor.
Bolger said: "He was impressive and he came on from his run at Leopardstown. We'll play it by ear with him now."
Wrekin Rock (7-1) collected the Keadeen Hotel Wedding Specialists Handicap for Jim Gorman and Michael Hussey.
Gorman said: "He would have been a good second but for falling at Punchestown.
"He's been on the go a long time now and he might have a rest. He could have some May grass and come back for Galway.
"There's a four-year-old hurdle on the Monday but he wouldn't go on the firm."
The David Wachman-trained Singing Bird (16-1) made a winning debut under Billy Lee in the P.G.Duffy & Sons Citroen Maiden.
