Alpha Centauri will have a workout over the weekend before connections decide whether to run her in the Tattersalls Falmouth Stakes at Newmarket on Friday week.
Connections have to make up their mind whether to head to the July Course and take on older fillies and mares, or wait for the Prix Jacques le Marois at Deauville on August 12, where she would clash with the colts.
Trained by Jessica Harrington, the daughter of Mastercraftsman has shown he is a cut above fillies of her own generation by running out a brilliant winner of both the Irish 1000 Guineas and Royal Ascot's Coronation Stakes.
"She's in good form. She will do a bit of work at the weekend after which Jessie Harrington will decide if she runs in the Falmouth or if she waits for the Jacques le Marois," said Alan Cooper, racing manager to owners the Niarchos family.
Alpha Centauri's brilliant victory at the Royal meeting was achieved in a course-record time, and in a race where she clashed with Billesdon Brook and Teppal, the winners of the English and French Guineas respectively.
Colm O'Donoghue simply guided his mount home by six majestic lengths from Threading, with Veracious third.
Cooper added: "She is clearly a very good filly and all credit to the staff at Commonstown."
