Paddy Twomey is likely to have a clearer idea about Deepone’s potential ambitions for the rest of the season after he makes his return in the P.W. McGrath Memorial Ballysax Stakes at Leopardstown on Sunday.

The Study Of Man colt finished off his juvenile campaign in fine style, winning the Group Two Beresford Stakes by a length and threequarters at the Curragh in September, his third success from five starts.

Prior to that, he came home fourth behind Diego Velazquez in the KPMG Champions Juvenile Stakes on Irish Champions Weekend at Leopardstown and was runner-up in the Churchill Stakes at Tipperary.

Deepone, who holds big-race entries in the Irish 2,000 Guineas and the Derby at Epsom, will take a step up in trip on his three-year-old debut for this recognised Classic trial over 10 furlongs, won previously by the likes of Galileo, High Chaparral, Fame And Glory and Harzand.

“He’s wintered well and I think it’s a good place to start,” said Twomey.

“He has a 5lb penalty for his win in the Beresford Stakes last season, but we’re looking forward to running him on Sunday.

“I think stepping up in trip will play to his strengths, I think a mile and a quarter to a mile and a half should be well within his compass.”

Aidan O’Brien has three entries as he goes in search of a 12th Ballysax success, including Illinois, a soft-ground scorer at the Curragh before finishing third behind stablemate Los Angeles in the Group One Criterium de Saint-Cloud.

Ocean Of Dreams made a huge impression on his racecourse debut at this track in October, romping home by six lengths on heavy going, while The Euphrates obliged on his second outing at Gowran Park when the mud was flying.

The field is completed by Dallas Star, with the Amo Racing-owned Zetland Stakes third making his first start for Adrian Murray after moving from the yard of Dominic Ffrench Davis.

Twomey has another promising three-year-old making a seasonal debut on the same card as A Lilac Rolla contests the Group Three Ballylinch Stud “Priory Belle” Stakes.

A filly by Harry Angel, A Lilac Rolla enjoyed a brief but flawless juvenile season, winning on her July debut at Cork before taking a Curragh fillies’ race by a head from Opera Singer the following month.

That form could hardly have worked out better, as Opera Singer went on to win the Group Three Newtownanner Stud Stakes by six and a half lengths and then the elite-level Prix Marcel Boussac by five lengths.

“She had a good year last year, she won her maiden and then she won her next race in good style,” Twomey said.

“She beat a very good filly in Opera Singer, she’s wintered well and is ready to start.

“The ground conditions may not be ideal but she’s in a good place and this is a good starting point for the season ahead.

“It was a good race (the Curragh race), she’s done well all winter and we’re looking forward to getting her started.”

Elsewhere in the seven-furlongs contest, there are four Ballydoyle runners in Buttons, Cherry Blossom, Greenfinch and Sweetest, with Donnacha O’Brien set to saddle Mysteries.

Joseph Murphy has entered Alpheratz, Jim Bolger is represented by Finsceal Luas and the field is completed by Natalia Lupini’s Kitty Rose, Noel Meade’s Money Dancer, Ger Lyons’ Wendla and the Alice Haynes-trained British raider Lexington Belle.

The other Group Three on the card is the Ballylinch Stud “Red Rocks” Stakes, which features Aidan O’Brien’s trio of Battle Cry, Samuel Colt and The Liffey, as well as Joseph O’Brien’s course and distance winner Atlantic Coast, plus Jack Davison’s dominant Madrid Handicap winner Take Me To Church.
