Nectaris saw off the market leader Juncture at the end of a mile in the fillies' handicap at the Curragh.
Nectaris made most of the running under Nathan Crosse but had Juncture for company a furlong and a half down.
The pair battled their way home for the first prize of €30,000 and it was 18/1 Nectaris who found that bit more close home to win by half a length.
Runner-up Juncture, who was dropping down from running unplaced in the Qipco 1,000 Guineas, went off 5/2f and was a length and a quarter in front of third-placed Miss Mirabell (9/2).
Jessica Harrington said: “She stayed going very well. She’s tough and loved that little ease in the ground.
“That was a lovely pot and I’d like to get a bit of black-type with her now.
“She enjoyed that going along there and she seems to have plenty of pace. She likes doing her own thing.” Additional reporting by Alan Magee
