Joseph O'Brien found himself riding the 14-1 outsider of the eight-strong field for the iRadio Race Night D'Arcy Derby Rated Race at Dundalk but it made no difference as the champion jockey got his mount home in front.

The James Nash-trained Our Manekineko already had three course and distance victories in the form book, but was coming off the back of three modest appearances over hurdles.

He took over the lead from Toccata Blue heading for the furlong pole and kept going under a strong drive to withstand the persistent challenge of Captain Cullen by a head.< Strategic Heights has shot up the handicap after three victories and it finally caught up with him in the iRadio Race Night Simon Stakes Apprentice Handicap even though he made a brave attempt to make it four.

The favourite held every chance at the furlong pole, but Sean Corby brought Catwilldo with a smooth run down the centre of the course and Garvan Donnelly's 4-1 shot edged in front close home to score by a short head.

Chris Hayes put Dancing Zafeen s experience to good use in the Irish Stallion Farms EBF Median Auction Maiden, leading all the way on Paul Deegan's 6-4 favourite and holding eyecatching newcomer Packing Go Go by a neck.

Hayes also attempted to lead all the way on Chillie Billie in the iRadio Race Night Handicap, but he was collared deep inside the final furlong and beaten a length and three-quarters by Tom Madden on the Shane Donohoe-trained Calling You (14-1).

Four placed runs suggested there was a race to be won with Lean And Keen and Sean Byrne's 5-4 favourite took the Crowne Plaza Hotel Dundalk Race & Stay Package Maiden with some authority under Pat Smullen, scoring by two and a half lengths.

There was plenty of money for Six Silver Lane in the iRadio Race Night Moore And Moyles Mile Handicap on his first start for John Feane, and the 2-1 favourite won well, taking over a furlong out under Colm O'Donoghue and holding Stoichkhov by three-quarters of a length.
