Sea The Lion and Gustavus Vassa respective first and second in the Cork Derby, renew rivalry at the Curragh this evening — but the Irish Stallion Farms EBF ‘Ragusa’ Handicap is far from a two-horse race.

Sea The Lion is actually bidding to go back-to-back in this mile-and-a-half heat.

Twelve months on, Jarlath Fahey’s great servant must contend with a 14Ib higher mark which equates to top weight for this assignment.

That will not be easy for the Sea The Stars gelding. He beat Gustavus Vassa by a nose at Cork and he meets that Willie Mullins-trained opponent 2Ib worse off now.

Mullins also has Law Girl in the mix, and this Listowel victor has the assistance of champion jockey Colin Keane.

Thirty-five minutes earlier, the Her.ie Apprentice Derby sees Change Of Velocity’s trainer Jim Bolger pitch Vocal Resurgence and Dawn Hoofer into battle.
