John Daly's propensity for drinking beer and smoking cigarettes is as well known as his ability to hit the ball 300-plus yards off the tee.

Daly is the subject of the upcoming ESPN 30 for 30 documentary "Hit it Hard," which will give an in-depth profile of his exploits on and off the course. In a clip from the film, Daly was asked about drinking during a tournament, which he denies ever doing ... except for one time at the L.A. Open.

"I never had any alcohol on the golf course that I remember, except for one time, and that was the L.A. Open," Daly says. "It was so slow and I played the back nine first. I think I'm 2 or 3 over. I went in the locker room and downed like five beers, and I think I shot 4 under on the front nine. That is the only time I know that I ever drank during a round, and I played great. I played great that week. I finished strong."

Daly noted that he had been hungover a lot on the course or was even still drunk from staying out until 3-5 a.m. when a round began, but the L.A. Open was the only time he actively drank during a tournament.
