Macarthur still on derby path

Aidan O’Brien is looking to Vodafone Derby hope Macarthur to improve on his seasonal bow and put up a much sharper performance in the Derrinstown Stud Derby Trial at Leopardstown on May 13.

A full-brother to 2005 Epsom hero Motivator, the son of Montjeu was beaten two lengths into third place by Mores Wells in the Ballysax Stakes last month, despite being sent off the 2-1 favourite.
