Kasey Kahne’s resurgence in the Chase continued Saturday night as he won the Bank of America 500 in Concord, N.C., in a late duel with Jimmie Johnson.

But the relentless Jeff Burton stayed on top of NASCAR’s playoff standings with a third-place finish, despite a severe vibration in his car during the late laps.

The win was Kahne’s sixth of the season, most on the Nextel Cup tour, and came back-to-back with a surprise second-place finish at Talladega, Ala., last week that lifted him from the bottom of the standings.

In two races, Kahne has gone from 273 points behind Burton to 160 back. After the fifth of the 10 Chase races, he is eighth in the standings, but two of the next three races come on tracks where he’s already won this season, Atlanta and Texas.
