Snow Fairy gave trainer Ed Dunlop a third win in the Darley Irish Oaks when completing a fillies' Classic double in brilliant fashion at the Curragh.
Supplemented for the showpiece after scoring at Epsom last month, the daughter of Intikhab looked a cut above the opposition as she strode away to win by eight lengths.
Once Ryan Moore asked her to quicken the response was instant and she stormed into the lead over a furlong out.
Snow Fairy (7-2) quickly burst clear and stamped her authority to win as she liked from Godolphin second-string Miss Jean Brodie (33-1) with Lady Lupus (66-1) doing best of Aidan O'Brien's five runners to take third a further three-quarters of a length away.
Epsom runner-up Meeznah, trained by David Lanigan, was fourth while Godolphin's main hope Hibaayeb (100-30 favourite) failed to act on the rain-softened ground and finished last.
O'Brien's Ice Empress set a strong early gallop and she had the field well strung out before Joseph O'Brien kicked Lady Lupus to the front at the turn for home.
Akdarena and Meeznah were also close up but Snow Fairy (7-2) had made eye-catching progress from midfield and was soon in command.
Dunlop, winning the race for a third time after Lailani (2001) and Ouija Board (2004), said: ‘That was a good performance. It was pretty spectacular really, the way she put the race to bed.
‘Ryan said she got bumped at one stage and she'd be better on better ground.
‘We were very confident she'd go well on decent ground so I was walking my box a bit today. It was the owner who decided to take the plunge and said go.
‘She is stronger than she was at Epsom and she has a huge heart.
‘The Yorkshire Oaks is a possibility now. I persuaded the owner to supplement her twice and I don't know if I'll ask her to do it again.
‘We'd have to start to think of going down a similar road to Ouija Board. I'm reliably informed that once everything is OK, she'll stay in training as a four-year-old.’
Moore was completing a 44-1 double after earlier steering Latin Love (9-1) to victory in the Kilboy Estate Stakes.
The David Wachman-trained filly was second to She's Our Mark in this Listed contest 12 months ago but went one better in the hands of Britain's champion jockey.
Moore hit the front a furlong out and grabbed the rail to bring Sue Magnier's filly home by a length and a quarter from Emulous, who edged out She's Our Mark for the runner-up spot.
‘The jockey was good on her, she likes an ease in the ground,’ said Wachman.
‘There's a good programme of fillies' Listed races in Ireland and we'll keep throwing our hat in the ring.’
Dunboyne Express (9-2) earned a quote of 14-1 for the 2000 Guineas with Paddy Power when romping home by eight lengths in the Group Three Jebel Ali Stables & Racecourse Anglesey Stakes.
The Shamardal colt, trained by Kevin Prendergast, shrugged off the attentions of evens favourite Samuel Morse to storm clear in the final furlong for Declan McDonogh.
Early leader Rudolf Valentino was third with the well-touted newcomer Glor Na Mara a disappointing last of four.
‘He's a smart horse, maybe the opposition didn't handle the ground but he likes it, it was nice, steady ground,’ said Prendergast.
‘He always shown us that he's a nice horse, he's come on a lot from Leopardstown and he learnt a lot.
‘If we get nice ground he could run in the Keeneland Phoenix Stakes, he is also in the National Stakes.’
McDonogh made it a brace on Bay Knight (12-1) in the bettor.com Rockingham Handicap for trainer Ken Condon.
Pathfork, a well-backed 9-2 second favourite floored the odds-on Robin Hood in the L Behan Tarmacadam & Asphalt EBF Maiden.
The Jessica Harrington-trained colt pulled away from Aidan O'Brien's charge inside the final furlong to score by four lengths in the hands of 3lb claimer Shane Foley.
‘He's a nice horse, he always worked better than the grey horse (Laughing Lashes who finished second at Leopardstown). We were a bit worried about the ground today,’ said Harrington.
‘He's in the Futurity so we'll see what happens, but I think he'll stay a mile after that performance.’
Trainer Pat Flynn and owner Pat Sweeney enjoyed an across-the-card double when Mon Champion (11-1), ridden by Lisa O'Neill, took the Thalgo Ladies Derby after Bahrain Storm's success in the Kevin McManus Bookmaker Grimes Hurdle at Tipperary.
