Aidan O'Brien's LAMBOURN resumed with a fine running-on second to stablemate Delacroix in Leopardstown's Ballysax Stakes and can continue his yard's fine record in this Group 3 now his stamina is unlocked more. Square d'Alboni ended last term with an emphatic victory in a Chantilly listed event and rates a big threat though, while Furthur, Lazy Griff and Pinhole all look open to further progress and can have a say too in an intriguing Chester Vase.
