Just Pretending made a quick return to action pay dividends as she took top honours in the Derrinstown Stud 1,000 Guineas Trial at Leopardstown.
The Aidan O'Brien-trained filly only broke her maiden at Navan on Tuesday and clearly has an appetite for racing.
Joseph O'Brien's mount (6-1) made noticeable progress at the three-furlong marker and made a positive move once straightened for home. David Wachman's Hint Of A Tint, who had been disappointing when favourite on her seasonal bow, put down a strong challenge but Just Pretending pulled out enough to prevail by a neck.
O'Brien senior said: "She is a funny lady. She gives trouble at the stalls and needs to be loaded early.
"She has loads of ability and she showed that at Navan. She could go for the Guineas (at the Curragh on May 26) now and she might step up to a mile and a quarter. She is a fine big filly."
