< Music Box made the most of a drop in class with a victory in the Parliament Premium Finance Irish EBF Fillies Handicap at Naas.

Aidan O'Brien's filly contested a Group Three at Fairyhouse on Wednesday but found this handicap more to her liking.

Donnacha O'Brien produced his mount to hit the front over furlong out and the 7-2 chance kept on well to hold fellow joint-favourite Miss Power by three-quarters of a length.

The O'Briens were already on the scoresheet after Seahenge created a big impression when making a winning debut in the opening caoga.com Irish EBF Maiden.

The yard's runners have rarely won first time out this year and the son of Scat Daddy struggled for a clear run, but picked up nicely once seeing daylight to beat Yulong Warrior by a neck in very cosy fashion.

The father and son partnership missed out on a treble when Rostropovich failed to land the odds behind Cameback in the J F Dunne Insurances Since 1977 Race.

The Ballydoyle representative was sent off 10-11 favourite for the three-runner contest but could not reel in the Ger Lyons-trained 15-8 chance, who was sent straight to the front by Colin Keane and repelled Strike For Freedom s challenge by a length.

O'Brien junior did get his three-timer when riding Eagle Spirit to victory for his brother, Joseph, in the Irish Risk Management Centre Handicap.

The 9-2 favourite came with a late rattle to deny Serefeli by three-quarters of a length in the dying strides.< Belle Boyd justified 8-13 favouritism with ease in the iBus PLC Irish EBF Fillies Maiden as Willie McCreery's charge dominated from the off and quickened clear to record a six-length verdict over Dayereh < Mo Henry sprang a 20-1 surprise in the J F Dunne Insurances Bus & Coach Insurance Apprentice Handicap, powering home from well off the pace to score by two lengths from Molans Mare for Adrian Keatley.

The market leaders dominated the concluding J F Dunne Insurances 40 Year Celebration Handicap as Less Of That (9-4) edged out 7-4 favourite Level Of Intensity by a neck.
