Zanoubiya was produced with a well-timed run to claim the concluding fillies maiden at Dundalk under Niall McCullagh.
The Dalakhani filly looked the second string from John Oxx's yard but proved a convincing winner.
The 9/2 shot chased down Faoileanda inside the final furlong to record a length success.
Stable-mate Askeria under Fran Berry, could only finish seventh while 7/4 favourite Endearing also proved disappointing in eleventh.
"They went a good gallop and when I switched out in the straight she ran home really well," said McCullagh afterwards.
"She might be good enough to win a handicap."
