Michael O’Callaghan expects Rionach to go close in the Racing Post Vincent O’Brien Ruby Stakes at Killarney on Wednesday.
Formerly trained by John Murphy, the daughter of Sea The Stars changed hands for 14,000 guineas last autumn and has proved a shrewd purchase.
The three-year-old has won twice from four starts for O’Callaghan, including a facile success over this course and distance on her penultimate start.
She was last seen finishing an excellent third behind Riven Light in the BMW Mile at the Galway Festival and O’Callaghan views this event as a good opportunity for her to pick up some black type.
O’Callaghan said: “She ran a super race in Galway considering she missed the break and got shuffled back.
“She came out of the race very well and we’re hoping she’ll go and put that behind her.
“She’s got form over the course and distance and we think she’s capable of winning a Listed race.
“We’re very hopeful.”
Rionach faces six rivals over a mile, with the field headed by Jessica Harrington’s Marshall Jennings.
The Fozzy Stack-trained Dream Ascot won over the course and distance on debut before finishing fifth at the Curragh. Stack also runs Harvestfortheworld.
Aidan O’Brien won this race in five successive years between 2008 and 2012 and relies on I Can Fly in a bid to claim his first victory since.
Mick Halford’s Petticoat and Check Your Pockets from John Kiely’s yard are the other runners.
