Rodgers was not among the contenders after hitting rounds of 67 and 69 but he had a superb start today with consecutive birdies at the first two holes before hitting a further three on the front nine alone.
The American picked up further shots at the 10th and 12th to out him 13-under-par.
Morgan Hoffman also had a stellar third round in what had been a tournament of polar opposites for the American with a first round of 74 followed by yesterday's 64.
Today he hit eight birdies and no bogies for a round of 63 to finish one stroke behind Rodgers, who was through seven holes.
Alongside him was David Hearn, the Canadian starting the day in a tie for fifth and picking up shots at the first two holes.
The pair were joined by defending champion Zach Johnson, Lucas Glover and Matt Jones - the trio who started the day in a three-way tie for the lead - JJ Henry, Daniel Summerhays and Troy Matteson.
