Bradshaw won four times by one stroke in regulation, and twice in playoffs.
"I started hitting the ball good," Bradshaw said. "I hit that shot on six, then started going from there. I found my golf swing there, and just kind of knew I would hit a putt eventually."
O'Dell had no qualms about losing to Bradshaw, who he felt was the best player in the tournament.
"I knew my number, but I knew I needed help," O'Dell said. "I didn't get the help, but of course I wasn't wishing him to (falter). It's a great course, great tournament and it got the best player winning it. There's no question, he's tough.
"I knew at some point he would have to do something out of the ordinary (to give me a chance). I was just trying to shoot my number and I pretty much did. Best player won, this week."
Christian Brand rallied with a 3-under in the final round to finish third, while Bob Friend finished at 3-under. Kenneth Hess and Bosten Miller finished 2-under and Philip Reale II, the brother of 2007 Amateur champion Anthony Reale, was at 1-under and one of seven players to finish under par. Woody Woodward, who shot 5-under in the second round to get into contention, finished even.
The 81st Open will be moving to The Glade Springs Resort's Cobb Course in 2014. It will return to the Cobb in 2017. Weirton's Williams Country Club and Bridgeport's Pete Dye Golf Club will host the Open in 2015 and 2016, although it hasn't been determined which course will host which year.
