O’Brien elects to run four in Epsom Derby

CHAMPION trainer Aidan O’Brien is to rely on a team of four in the Vodafone Derby on Saturday as he bids to win the blue riband for a record third consecutive year.

His representatives from the seven left in at the second forfeit stage are set to be ante-post favourite Brian Boru, Alberto Giacometti, Balestrini and The Great Gatsby.

With stable jockey Michael Kinane opting for Brian Boru, O'Brien outlined his other riding arrangements for Saturday's Classic at Epsom.
