Porta Fortuna is pencilled in to make her seasonal bow in the Ballylinch Stud ‘Priory Belle’ 1,000 Guineas Trial Stakes at Leopardstown in early April.

The Caravaggio filly landed the Albany Stakes at Royal Ascot last year before going on to place in both the Phoenix and Moyglare, before striking Group One gold in the Cheveley Park Stakes at Newmarket.

Trainer Donnacha O’Brien then headed to America where Porta Fortuna was only narrowly denied in the Breeders’ Cup Juvenile Fillies Turf, beaten just half a length by Hard To Justify.

O’Brien admits her juvenile brilliance raises some doubts ahead of her Classic campaign, with a trial run dependent on conditions suiting at Leopardstown.

In a stable tour for Attheraces.com, he said: “She was brilliant for us last season. When they are so good as two-year-olds, you can never be sure how well they’ll train on, but she seems to have wintered particularly well and her recent work has been very good.

“I’d like to run her in the 1,000 Guineas Trial at Leopardstown on April 7, but if the ground is bad, I’ll be happy enough to give her a racecourse gallop instead and go straight to the 1000 Guineas at Newmarket.”

Porta Fortuna is a best-priced 25-1 with Paddy Power for the 1000 Guineas on May 5.
