"He might travel that little bit kinder and the little gear change today, the winkers, helped.
"It got his mind on the job, and he put the race to bed which was good."
Hayes said if the stable elects to send Arkansaw Kid to the Sir Rupert Clarke the extra distance should not pose a problem with the gelding beaten narrowly in The Supernova at Pakenham last December.
Sent out the $3.20 favourite under Blake Shinn, Arkansaw Kid defeated the 2023 Bobbie Lewis winner Star Patrol ($7) by a half-length with Media World ($8) a further three-quarters-of-a-length away third.
Hayes said Arkansaw Kid had come of age as a five-year-old and improved enormously from his days as a three-year-old colt.
He said wide barriers in his first two runs of the campaign at Caulfield had worked against him.
"We thought he had come of age this preparation and it just hasn't gone to plan in his first two runs this preparation," Hayes said.
"He's a horse that is never far away and we've always thought he was a Group 1 horse, especially in a handicap and he proved that today.
