Mango Diva gave trainer Michael Stoute a second Denny Cordell Lavarack & Lanwades Stud Fillies Stakes win in five years with a cosy success in the Group Three event at Gowran.
Ave struck for the Newmarket trainer in 2009 and Mango Diva continued her progression after landing a Listed race at Salisbury last month.
Last year's winner Aloof made the running until two furlongs out where Uleavemebreathless came with a strong run that looked like prevailing but it was covered by Johnny Murtagh on Mango Diva.
Leading inside the final furlong, the 7-4 favourite drew clear in the closing stages to win by one length.
"She pulled up a bit after she hit the front, she's a bit cautious and was watching everything but she is going the right way," said Murtagh.
"When I eased her out I always thought I was going to win.
"I gave her a smack and she quickened up well - she's with the right man."
Mandatario (13-2) made a winning start to his career when hanging on for victory in the Powerstown Stud European Breeders Fund Maiden.
In doing so, the Jim Bolger-trained newcomer was following his top-class stablemate Trading Leather, who won this mile event 12 months ago.
Kevin Manning's colt was in the box seat two furlongs out but had to withstand a strong challenge from Kerkeni, who made up plenty of ground before failing by a short head.
Bolger was at Croke Park for the All-Ireland Football final, but his assistant Ger Flynn said: "Kevin said he's a big immature horse but he was smart away and did it well.
"It's very unusual to win here from such a bad draw (14) and he looks like a nice horse for the future."
Odisseia (6-1) got off the mark at the fourth attempt with a gutsy performance in the Dining Packages on gowaranpark.ie Nursery.
Eddie Lynam's youngster was handy throughout and found plenty when Ava's Star put down a strong challenge through the final furlong and a half to win by half a length under 5lb claimer Colin Keane.
Lynam was represented by his brother, John, who said: "She kept at it well and we're in the hands of the handicapper now."
Gavin Cromwell's Sretaw (8-1) took full advantage of Maal drifting across the track to take division one of the Tommy Tiernan Live After Racing Fri Oct 4th Handicap.
Sretaw stayed straight on the far side after being driven by the in-form Chris Hayes and was a length and a quarter to the good at the line.
"I was just told to make use of the draw (one), but I kept having to pull back and give away ground," said Hayes.
"Turning in I was starting to make up my excuses, but it just opened up like the red sea and she won snug enough in the end."
Wagadoogoochoochoo (20-1) shed her maiden tag at the 10th time of asking when coming with a sweeping run to take division two and give Castlecomer-based Pat Murphy a first training success.
The four-year-old quickened up smartly for Declan McDonogh to account for New Regalia and Hoppsan by two and a half lengths and a head.
King Of Oriel (6-1) proved three-quarters of a length too good for the favourite Carenza in the Gowran Golf Memberships For 2014 749 Euro Apprentice Handicap.
Winning rider Marc Monaghan said: "He's a nice little horse and he just got nabbed on the line at Fairyhouse. I tried to keep him covered up as long as I could and when I went for him he kept going well."
The Michael Halford-trained Castle Guest justified 4-1 favouritism when galloping to a two and a quarter length call under Shane Foley over Magnolia Ridge in the gowranpark.ie Rated Race.
