Like father, like son! Chip off the old block has a yard packed with talent

It's hard to believe that last Sunday marked the fourth anniversary of Joseph O'Brien's remarkable four-timer on his first day as a trainer in 2016.

The 27-year-old has packed an incredible amount into a short period of time and the 2020 Flat season looks poised to deliver further success for the Owning Hill handler.

He may be without brilliant Breeders' Cup heroine Iridessa, who has been retired after sustaining an injury and sold on for a breeding career in Japan, but his impressive squad looks well stocked with quality on all fronts.
