Denis Linehan continued his good form at Dundalk by steering Rock On Dandy home in front in the two-mile ASM Chartered Accountants Race.
Linehan, who struck with his only two rides at last week's meeting, was content to watch on from the rear on Fergal Birrane's grey as Asbury Boss cut out the running.
Zaofu hit the front approaching the furlong marker travelling well, but Linehan had Rock On Dandy motoring down the centre of the track and only needed hands and heels to get the 100-30 shot home by two and a quarter lengths.
Birrane said: "We knew from his work at home that he could do a bit more than a mile and a half, but the way he won today impressed me.
"He took a hold at the start and got a bit buzzed up but Denis did a good job and got him settled.
"He could go hurdling in the future. We haven't schooled him yet but we're hoping he'll jump them.
"It's been a lucky place for us here. We have a Polytrack gallop at home and we also have the beach (at Killala, Co Mayo) so it suits us here.
"We have more coming in for the grass in the next couple of weeks."
Nivvo was second to Zaofu at the first meeting of the year here, and went one better in the Celtic Adventures Fillies Maiden.
The 8-11 favourite raced in second until taking it up at the top of the straight, and Pat Smullen kept her up to her work to dispose of Cavelli by three-quarters of a length.
It was the daughter of Dylan Thomas' 12th start, and trainer Tracey Collins said: "She was due that and, in fairness, she's been very consistent and has run into some good horses in her maidens.
"She has a good pedigree and it was important that she won a maiden.
"We dropped her back because it was a fillies' maiden and Pat gave her a lovely ride. She quickened well and put it to bed, really, turning in.
"I'd have no problem running her again over a mile or further. Tonight is the first time she was drawn well and Pat made full use of it. I think she won because it was a strongly-run mile."
