The colt, ridden by Flavian Prat for American trainer John Sadler has been called the best American horse since the legendary Secretariat.

Flightline stormed home to go unbeaten in the Classic on Saturday, winning six races from six runs.

A crowd of 45,973 roared the horse on as it won by a record-breaking 8 1/4 lengths.

Speaking after the race, trainer Sadler said: “It was a beautiful ride. No panic on (Flavien Prat’s) part. He let the horse do the running. We’re thrilled. It’s not about me, it’s about the horse. He’s a great horse.

“A great win today. He just ran beautiful; just like we thought he could. It’s wonderful when it all works out. That’s a very good horse that was second. This os one of the greatest horses of all time.”
