Daly, 28, avoided a play-off when he sank a five-foot putt at the Atlanta Country Club on Sunday, giving him his third victory on the PGA Tour.
Daly, who collected dollars 216,000 (pounds 145,000), carded a level-par 72 to finish with a 14-under total of 274, one stroke ahead of Brian Henninger and the defending champion, Nolan Henke.
'I wasn't this nervous playing golf when I was drinking,' said Daly who has not had a drink in more than a year. 'It's the first tournament I've won on the PGA Tour in a sober manner, so it's a great feeling knowing I can do it sober. I don't think two years ago I could have pulled this off.'
After serving a four-month suspension from the tour following a series of controversial incidents, he returned in March but had been inconsistent before he
arrived at this tournament. He also spent the previous day in Orlando at a court hearing over visitation rights to see his daughter.
'I'm still shaking. This is great. I dedicate this tournament to my little two-year-old daughter.'Reuse content
