Earlier on Wednesday, he was given his first run at Belmont Park in Elmont, N.Y., jogging around the 11/2-mile dirt track under the guidance of exercise rider Hector Ramos.
"We took him to the track and jogged him once around, and he looked absolutely super," said Jack Sisterson, assistant to trainer Doug O'Neill.
"The way he looked was everything and more I'd want to see in him. Energy level was high, got over the ground well, ate up everything last night."
Sisterson said I'll Have Another, bidding to become the first horse since Affirmed in 1978 to win the Triple Crown, would have another jog today and possibly gallop for the first time Friday.
The final field for the $1 million race June 9 will not be decided until a few days before the race, but the connections of I'll Have Another's chief rivals, Union Rags and Dullahan, are showing confidence.
Both horses were beaten by I'll Have Another in the Kentucky Derby but are fresh after skipping the Preakness to concentrate on the final leg.
"I wouldn't be going in [the Belmont] if I didn't think he could beat I'll Have Another," said Michael Matz, trainer of Union Rags. "He's a big horse, and once he gets into a nice rhythm … that's why we went with [jockey] John Velazquez. He knows New York."Copyright © 2015, The Baltimore Sun
