For the sixth time since 2011, trainer Aidan O’Brien and jockey Ryan Moore teamed up to win the $1 million Breeders’ Cup Juvenile Turf (G1), taking Friday’s renewal at Santa Anita with Unquestionable.

International participation during Breeders’ Cup Friday has come up strong. Horses representing England, Ireland, France, and Japan are among the entries.

Favored Justify filly Ramatuelle appeared to have made the winning move in Sunday’s Prix Morny (G1), but British shipper Vandeek picked up strongly to deny her in Deauville’s “Win and You’re In” for the Breeders’ Cup Juvenile Turf Sprint (G1).

A pair of winners on 2023 opening day made world-renowned trainer Aidan O’Brien the winningest trainer in Royal Ascot history.
