If not for a brief virus, Highland Chief would have contested last Saturday’s Joe Hirsch Turf Classic (G1) at Aqueduct. But trainer Graham Motion’s fallback plan worked out just fine.

Godolphin’s homebred Santin, who broke through with his first stakes win in the Turf Classic (G1) on Kentucky Derby Day, followed up over the same Churchill Downs course and distance in Saturday’s Arlington Million (G1).

Jockey Julien Leparoux scored his 1,000th Churchill Downs win on Stephen Foster Preview Day, with a well-judged ride aboard Walkathon in the Regret (G3). Later, comebacker Admission Office rolled late to deny Get Smokin in the Arlington (G3).
