Irish trainer Aidan O’Brien has described his latest horse, the Golden Jubilee Stakes-winning, Starspangledbanner, as “the Usain Bolt of horse racing”.

Although the renowned trainer has prepared many champions and won more than 150 Group One races around the world he thought that Starspangledbanner was particularly speedy.

"We have never had anything like this fellow," O'Brien said. "When I'm in my jeep at trackwork in the morning, he would go straight by me. I have never seen a horse go so fast. His fractions are incredible. Horses don't go 9.5 seconds to the furlong [200 meters] in their work at Ballydoyle, but this colt did that in his final gallop before this race. I'm not going to say he's the Usain Bolt of horse racing - I'd be accused of 'hyping' him - but I can say these are the facts. His times were there in black and white. I've got to admit we had to go back and check them to make sure the GPS systems were right, but that's him. He's a great horse."

The colt won the Stakes in just one minute 12.57 seconds, setting a race record in the process.

The lightning-quick horse finished ahead of English sprinter Society Rock (50/1) who came in  a head in front of America's Kinsale King (8/1). Starspangledbanner was the 13/2 joint favourite for the coveted prize.

The Australian horse was described by fellow Irish jockey Jonny Murtagh as a “big” and “strong” horse who was very similar to Choisir, another powerhouse.

Starspangledbanner's win was the second Royal Ascot coup in three years by an Australian galloper that has been purchased by Coolmore Stud as a potential stud prospect and sent to O'Brien to race.
