The 'Battlefield Promotion' stipulates that any player with three wins in one season on the Buy.Com Tour automatically moves up to the PGA Tour. With two other wins at this year's Richmond Open and Permian Basin Open, Campbell was able to join Heath Slocum as the only players to make the move to the main tour through this measure in 2001.
Chris Smith was the first Buy.com Tour player to get bumped up to the PGA Tour when he titled three times in 1997.
'That was what I was shooting for,' said Campbell, who finished the tournament at 8-under-par 280. 'It's my fifth year and it's nice to make it. After my second win, the goal became to finish first on the money list or win again.'
Campbell's first-place check for $81,000 pushed his season earnings to $363,959, a new record for the Buy.Com Tour.
The 27-year-old was in a duel with Deane Pappas down the stretch as the players distanced themselves from the field. Third-round leader Tom Carter fell off the pace by going five-over through 12 holes, while Tim Clark, who was in second after Saturday's third round, was four-over through 10 holes.
At the 10th, Campbell ran home a 10-foot birdie putt to match Pappas atop the leaderboard but Pappas answered at the next hole with a 20-foot birdie to take a one-shot lead.
Campbell birdied the 15th to draw even and then knocked an 8-iron to three feet at the last. Pappas missed his birdie opportunity on No. 18 and Campbell converted his to earn his spot in the big leagues.
'I was excited, but just didn't show it,' said Campbell. 'Getting on the back nine with a chance to win is why you play tournaments. Being in competition is why you play the game.'
'Chad has been playing well all year,' said Pappas, who carded a 2-under 70 on Sunday. 'We both were getting up and down and playing well. It was good golf.'
Carter closed with a 4-over 76 to tie for third place with Charley Hoffman and first-round leader Vic Wilk at 3-under 285. Clark, who also shot 76, finished alone in sixth at minus-two.
