Speaking after the first round at the PGA Championship, Daly said he had applied to the R&A organising body for permission to ride at Royal Portrush for the July l8-21 tournament and was awaiting a reply.
Daly, who has an arthritic right knee and walks with a slight limp, is riding a cart at the PGA Championship under the Americans with Disabilities Act (ADA).
"Ireland is big on the ADA like most countries should be," Daly told reporters at Bethpage Black.
"Trust me, if I could walk I would rather walk. I feel like I always have played better when I walk.

"I'm not one who wants to ride all the time. It's just something, if I don't I'm not going to be able to play, not going to be able to finish."
Daly walked two years ago at Royal Birkdale, where he missed the cut, and did not play last year.
He ruled out walking at Portrush.
"I wouldn't be able to," said the 53-year-old American.
"Hard pan (surfaces typical of links courses) is better to walk on. I would probably get nine holes and that would be about it.
"Out here (I could walk) maybe four before I couldn't even swing."
