Coolmore and Westerberg's Endorsement (Wootton Bassett) was last seen finishing third behind James J Braddock (Zarak) and Pierre Bonnard (Camelot) in Leopardstown's G3 Derby Trial last month and boosted the hopes of those G1 Derby candidates with a seven-length romp in Thursday's Listed King George V Cup back at the Foxrock venue.“His form is solid, it was nice to see him running well and Ryan [Moore] was very happy with him,” commented Aidan O'Brien. “We didn't know how far he'd stay because a mile-and-a-quarter is as far as he's gone. He could be a [G2 Queen's] Vase horse or he could be a [G2] King Edward [VII] horse. We were thinking he might be a Vase horse, so it's possible he could be.”Clear on the front end throughout, the 1-4 pick straightened for home with a commanding advantage and was urged further clear in the straight to easily rout stablemate Amadeus Mozart (Wootton Bassett) by daylight.The Joseph O'Brien-trained duo Yousaynothingatall (Australia) and So Must I (Sottsass) came home at intervals, 4 1/4 lengths and 11 lengths back in third and fourth. IN A ROMP! Group 1-entered Endorsement is miles too good in the King George V Cup. pic.twitter.com/VbhkSDOgqv— Leopardstown RC (@LeopardstownRC) June 4, 2026The post Endorsement Boosts Derby Candidates With Leopardstown Romp appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
