John Daly Hits Up Hooters, Casino After PGA Championship Round

John Daly relaxed after the first round of the PGA Championship in the most John Daly way possible -- grabbing some wings at Hooters and hitting the casino.

The golf legend -- who is tied for 58th after shooting 2-over on Thursday -- posed with 6 Hooters girls in Tulsa just hours after hitting the links ... thanking the workers for their hospitality.

As it turns out, the dude didn't stop there -- he was spotted posted up at the slots on Thursday night as well ... with a Diet Coke and a pack of cigs sitting next to his machine.

Naturally, TMZ Sports had to hit Daly up to see if he had any luck at the casino ... and unfortunately, it just wasn't his day.

"The slots weren't hitting," Daly told us this morning.

Of course, Daly is known for his obsession with the wing joint ... and his love for the place eventually landed him a sponsorship with the chain.

We'll have to see if Daly's post-golf routine keeps him in the groove for round 2 -- he tees off at 12:25 PM Central time.
