Greg Biffle is still seeking his first win of the 2011 season, and thus far the Roush-Fenway Racing driver appears to have a very real opportunity to take tonight's Bank of America 500. After 100 of 334 laps around the 1.5-mile Charlotte Motor Speedway, Biffle leads. Pole-sitter Tony Stewart runs second, followed by Matt Kenseth, Jimmie Johnson, and Ryan Newman.
The rest of the top-10 features Unadilla, GA, native David Ragan, Carl Edwards, A.J. Allmendinger, Trevor Bayne, and Kevin Harvick.
Drivers outside the top-10 but in the Chase for the Sprint Cup title include Denny Hamlin (12th), Kyle Busch (15th after starting at the rear of the field), Kurt Busch (19th), Brad Keselowski (25th), and Jeff Gordon (27th).
There has been but one caution flag through the opening 100 circuits, for debris at lap 77. Newman and Harvick took only two tires on their pit stops under the caution flag to pick up track position, but both have drifted back since the race restarted.
