Updates from the opening day’s card at York
Constitution River can fill Bow Echo void | Mail Greg
International Stakes contender: Constitution River
Age: 3. Runs: 6. Wins: 5. Group One wins: 2.
Trainer: Aidan O’Brien. Timeform rating: 134.
Aidan O’Brien’s main contender has taken on the mantle of the season’s leading three-year-old in training since the unfortunate news last week that Bow Echo, the Sussex Stakes winner, had been retired due to injury. After just six starts, he is already on a world rating of 124, 7lb behind Ombudsman, and has obvious scope to close the gap, at the very least, on the Knavesmire today.
