Flanagan, who has played eight events on the Web.Com Tour this season for a win, six missed cuts and a 66th place finish, eagled the par five 18th for the second day and added five other birdies.
Flanagan has slipped to 24th on the money list so needs a good week or two to play his way back to the PGA Tour. A victory this week would guarantee his place on the bigger stage next year but even just a confidence building week would be welcome given his recent efforts.
James Nitties is the next best Australian in 11th position.
