Odds-on favorite St Mark’s Basilica survived an inquiry in the Breeders’ Cup “Win and You’re In” Irish Champion (G1), but otherwise upsets were the order of the day at Leopardstown.

Three Breeders’ Cup Challenge events are on tap at Saturday’s kickoff of Irish Champions Weekend at Leopardstown.

A change in venue and surface made no difference to Kameko, who upended a Coolmore-owned juggernaut in Friday's Vertem Futurity Trophy (G1) at Newcastle.

Originally the Vertem Futurity was scheduled fover the turf at Doncaster, transferred due weather to the synthetic Tapeta track at Newcastle.

To say that conditioner Aidan O’Brien has endured some success in the Beresford Stakes (Ire-G2) is a massive understatement.
