O'Brien seven in Beresford contention Aidan O'Brien is responsible for seven of the 10 remaining horses in contention for the Juddmonte Beresford Stakes at Naas on Sunday. The Ballydoyle handler is chasing a 17th Beresford victory within the last 22 years, with St Leger hero Capri the latest inmate to have obliged. O'Brien's team this year could be spearheaded by Saxon Warrior and Nelson, who are both quoted at around the 20-1 mark about winning next season's Epsom Derby. Berkeley Square, Coat Of Arms, Delano Roosevelt, Kew Gardens and Rostropovich have also been entered by the master trainer. Warm The Voice has won his last three races and could offer the sternest challenge to the O'Brien battalion if Brendan Duke gives him the go-ahead in the Group Two over a mile. The Aga Khan duo of Riyazan and Hazapour, who won at Galway on Tuesday, complete the list of possible runners.
