Owner Andrew Tinkler's Irish operation picked up a valuable dividend when the progressive three-year-old Ursa Major took the feature Derby Festival Irish Stallion Farms EBF Handicap at the Curragh.

Never out of the first two in four starts for the Tommy Carmody team, the son of Galileo was following up a seven-length victory over the same course and distance earlier this month, having gone up 10lb.

Niall McCullagh came down the wide outside in the straight with a long sweeping run on the 11-4 favourite and beat Buy Back Bob by a length and a half.< Shamiran (8-1) won over hurdles at the Punchestown Festival in April and made it a notable double by landing the Eflow Rewards Apprentice Derby for trainer Stephen Nolan.

Shane Foley nudged him up to join leader Paene Magnus at the furlong pole and he quickened nicely clear to beat the staying-on Lady Jock by three and a half lengths.

Halford and Foley completed a double when Massiyn (8-1) collared Vedani close home to take the Silken Thomas Handicap by half a length, with both protagonists running in the colours of the Aga Khan.
