Rue Bonaparte opened her account at the second attempt with a hard-fought success in the Irish Stallion Farms EBF Fillies Maiden at Naas.
Kevin Prendergast's Dark Angel filly had finished second on her debut over the course and distance last month but had to dig deep to land the spoils.
Leading a furlong out, Chris Hayes kept the 6-4 favourite up to her work to hold the late bid of market rival Californiadreaming.
Prendergast said: "I'd say that wasn't a bad race. We'll bring her back here for the Swordlestown (Listed Coolmore Stud Fillies Sprint, June 1) and try and get a bit of black type, although that race could be a different kettle of fish.
"I'd say that's the sort of ground she likes and I don't think she'd go on brick hard. Most of the Dark Angels don't and she's from a soft-ground family. The grand-dam Rebelline couldn't run unless it was soft."
