Paene Magnus opened a big weekend for the Jim Bolger yard by winning the feature Listed contest at Dundalk, the Carlingford Stakes.
Kevin Manning, who will be riding Dawn Approach and Parish Hall for the stable in the big races on Ascot's Champions Day card, set out to make all on the 7-1 chance, a winner at the track three times around this time last year.
The top-weight was hounded by Manalapan all the way down the straight, but stuck to his task to score by a head, with odds-on favourite Afonso De Sousa unable to get to them in third.
Despite the latter's defeat it was a great night for Joseph O'Brien, who landed a treble that included his father Aidan's juvenile Masai (2-5 favourite), who cleared away in the final furlong to win the Irish Stallion Farms EBF (C & G) Maiden by three and a half lengths.
The young jockey had earlier won on Dot Love's 7-4 chance Principessa Ava, who collared odds-on favourite Peony Fairy a furlong out in the Irish Stallion Farms EBF Fillies Maiden and forged a length and a half clear to give the trainer her first juvenile success.
The treble came up when O'Brien delivered Denis Cullen's Total Reality (5-1) with a surging run from the rear to take the first division of the Crowne Plaza Leading Jockey & Trainer Championship Handicap by a length and three-quarters.
Ger Lyons' Queen Of The Sand (7-1) won on her last visit to the all-weather track almost a year ago and swooped late under Gary Carroll to take the Irish Stallion Farms EBF Fillies Handicap, nailing Sassaway in the last few yards to win by half a length.
David Marnane's 7-2 joint-favourite Zalty wore down Toccata Blue coming down the straight in the Crowne Plaza Race & Stay Package Handicap to score by three-quarters of a length under Fergal Lynch.
