MARTINSVILLE, Va. -- Trouble finally found Jeff Burton at Martinsville Speedway. Jimmie Johnson and a handful of other championship chasers found themselves back in title contention.
NASCAR's Chase for the championship broke wide open Sunday, setting up what is likely to be a wild four-race finish.
Johnson took the lead from Bobby Labonte with 55 laps to go and held it through several restarts to win the crash-filled Subway 500, while 2003 champion Matt Kenseth replaced Burton atop the standings.
Johnson moved from seventh to third in the standings with four races left, and appears to be the driver with the most momentum heading into the final month.
Kenseth assumed the points lead when Burton pulled his car into the garage after just 217 laps because of engine trouble, and most everyone took advantage.
Next week in Atlanta, seven drivers will start within 99 points of Kenseth.
