The Ballydoyle team, successful in the day's feature with Fame And Glory, also struck at Navan with Cristoforo Colombo and Offer.
The former could go to Royal Ascot after making a winning debut in the Irish Stallion Farms EBF Maiden.
He struck the front a furlong and a half from home, taking a couple of lengths out of the field in a matter of strides and went on to score cosily by a length and a half from Scream Blue Murder.
"He jumped and travelled well and was quite green in front," said winning rider Joseph O'Brien.
"He's by Henrythenavigator who was a good moving horse and he would appreciate a bit faster ground."
Tammy O'Brien, representing the owner Mrs John Magnier, added: "He is likely to be part of the Royal Ascot team."
Offer (1-9) duly landed the odds in the navanracecourse.ie Maiden as he opened his account with the minimum of fuss, coming home four and a quarter lengths ahead of newcomer Civil War.
My Girl Anna (9-2 favourite) just held Luisant by a nose in the navracecourse.ie Handicap for trainer Muredach Kelly and jockey Rory Cleary.
"She's always knocking on the door. We decided to change tactics a bit today and held on to her for a while," Cleary said.
"She just held on in the finish but she deserved it."
Andrew Oliver's Jazz Girl (5-1) was a game winner of the Irish Stallion Farms EBF Fillies' Handicap under Chris Hayes.
"Chris gave her a great ride and she did it well," said Oliver.
"I was a bit worried beforehand about the ground, but it dried up and she has done it well from the front.
"We'll give her a few weeks break and she'll continue handicapping around that trip."
Johnny Murtagh guided Kashmir Peak (6-1) to victory in the Come Racing on June 9th Handicap for trainer Ger Lyons while the Tommy Stack-trained Coin Of Courage (20-1) just lasted home in the Irish Stallion Farms EBF Maiden under Billy Lee.
