Daly, the subject an ESPN "30 for 30" documentary, says in a show clip that he drank beer during the L.A. Open, now known as the Genesis Open.
"It was so slow and I played the back nine first," Daly says. "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."
