After birdieing the final two holes of regulation to force the extra session, Owen came up short on a 12-foot birdie putt to give Damron the title in the Nationwide Tour event.
It sounds bad to say that I hit it terribly, but I really did, said Damron, who earned $94,500 to move to No. 7 on the money list.
I flirted with trouble all week long but I came out smelling like a rose. A hot putter makes up for a lot of mistakes. I cant count the number of putts I made over 20 feet this week, maybe five or six. I made tons from 10 to 20 feet.
Damron shot a 66-under 66 to match Owen (71) at 11-under 277. Casey Wittenberg (67) was a stroke back, and Roger Tambellini (67) and Vance Veazey (68) at 9 under.
Much of the attention was on 22-year-old rookie Brendon Todd, a four-time All-American at Georgia who had the second-round lead and shared the 54-hole lead with Owen at 10 under par. But Todd closed with an 8-over 80 to tie for 25th.
That left the stage to Damron, who charged through the pack, reeling off five birdies in a six-hole stretch to make the turn at 10 under.
I didnt think Id have much of a chance to win today, said Damron, who started the day five shots off the pace. I thought Id get 2 or 3 under, make a nice check and go about my business. I just hit that stretch that gets momentum going. When I made the turn I figured I had a good chance.
