Joseph O'Brien's evening got even better when Tissiak scorched home in the fillies' maiden at the Curragh to give him a treble and an across-the card quad.
The 11/8 favourite tracked the leaders in third before travelling sweetly into contention, on the outer, approaching the straight.
She was given the office over two furlongs from home by Donnacha O'Brien and shot clear.
She had put her rivals away by the final furlong and came home by two lengths from the closing Lure Of the Sea (2/1).
The runner-up was a neck in front of Bongiorno (20/1) who also kept on well.
Joseph O'Brien said: "It's been a great evening, and we thought she was probably our best chance.
"She is a beautiful filly and had two very good runs. She has a fantastic pedigree, and will probably step up to a Stakes race now.
"She is in the Irish Oaks and we will probably work back from there now.
"Donnacha said he was going so easy that he thought it was going to turn into a sprint and he put her in gear. All of a sudden she took off on him and he had to stay going. I don't think he's ridden her before so he'll know her now for the next day."
O'Brien's other winners on this card were Dom Carlos (11/1) and Remmy D at 7/2. He also landed the mares' bumper in Clonmel with 4/1 shot Beautiful Citi
Donnacha O'Brien had a double at the Curragh on Dom Carlos and Tissiak.
