Joe Affrunti fired a 4-under 68 Saturday to maintain his lead after 54 holes of the Nationwide Tour's Chattanooga Classic. Affrunti missed a 6-foot eagle putt on the par-5 18th but still tapped in for birdie to give himself a lead over veteran David Branshaw. Affrunti, who led by two after the second day, stands at 18-under after three trips around the Black Creek Club, one better than Branshaw, who fired a 7-under 65. Rob Oppenheim matched the day's best score with an 8-under 64 and holds down third place at 14-under, four back. Scott Gardiner (68) and Ryan Armour (70) are next at 13-under and will assume the chase position for Sunday's finale. read more: http://www.pgatour.com/2010/tournaments/h082/10/09/rd3-wrap/
