O'Brien dominates Derby field

Aidan O’Brien is responsible for 36 of the 138 horses remaining in the Derby after the first forfeit stage as the Ballydoyle trainer looks to capture the £1.25m (€1.4m) Classic for a third time at Epsom on June 6.

His team includes dual Group One scorer Mastercraftsman, Group Three winner Rip Van Winkle, and Westphalia, runner-up in the Breeders’ Cup Juvenile Turf after winning the Champagne Stakes at Doncaster.
