As the result of his victory in the Group 1 King George VI and Queen Elizabeth Stakes, Hukum has joined Mostahdaf in the second position in the sixth edition of the world’s best racehorse rankings for 2023.

Hukum earned his rating when he defeated Westover by a head in the King George, while King of Steel was third and Luxembourg was fourth.

Among U.S.-based horses, White Abarrio Joins the rankings after his victory in the Whitney Stakes (G1), which he won by a margin of 6 1/4 lengths. He came into the race after finishing third in the Metropolitan Handicap (G1). He’s tied with Cody’s Wish and five others for 12th place in the rankings.
