At the moment Costantino Rocca holed the spectacular 50-foot putt to force a play-off, all power failed in Daly's home town of Dardanelle, Arkansas, because of a storm.
It meant that none of the 4,000 citizens could watch the first two holes as the former US PGA champion did battle with the Italian.
"My mum Lou and dad Jim drove 30 miles to my aunt's house," Daly said. "It is probably the first time they have broken the speed limit. The whole town was going nuts when the power failed.
"There has been a lot of response at home, which makes me kind of want to go home. It has not hit me yet. After winning, all the players have been really great and they all congratulated me.
"I have not had as much pressure on me since starting the game. Your legs shake, your hands shake, your whole body shakes. I have not shaken that much since three months out of rehab," the former alcoholic said.
Daly has stayed in Europe in order to play in the Heineken Dutch Open, which starts at Hilversum today, and the Scandinavian Masters in Sweden next week.
He has been paired today with Colin Montgomerie, who missed the cut at St Andrews, and the defending champion, Miguel Angel Jimenez of Spain.
"I am happy to be still here in Europe, to let it set in and to focus on this tournament and also Sweden next week," Daly said. "I had no thoughts about pulling out. This is a beautiful golf course, a bit like an American course. I have been hitting a lot of irons off the tee. I just hope it rains to soften the fairways up.
"There are a lot of holes here that are narrow and tricky and are not driveable. But I'll maybe pull the driver out on the par fives if I need to be aggressive."Reuse content
