Alpha Centauri bounced back to her best to win the Tattersalls Irish 1,000 Guineas at the Curragh.

A Royal Ascot runner-up last season, she was beaten a long way on her only run this campaign in April.

Back on good ground, however, she reeled in long-time leader Could It Be Love to give Jessica Harrington a Classic success to go with her Cheltenham Gold Cup win of last year.

Colm O'Donoghue was on board the 12-1 shot, while the heavily-backed 5-4 favourite Happily could finish only third.
