Archipenko delivers in Derrinstown

Archipenko sprung a minor surprise as he saw off his short-priced stablemate Macarthur in the Derrinstown Stud Derby Trial at Leopardstown.

Aidan O’Brien fielded no less than four of the five runners with Macarthur, a full-brother to 2005 Vodafone Derby hero Motivator, being sent off the 8-11 favourite.
