In 2013, the 10-race Chase for the NASCAR Sprint Cup will decide the NASCAR Sprint Cup Series championship for the 10th-consecutive season.
The Chase was implemented in 2004 to involve more drivers in the championship hunt, and intensify fan interest and drama in a playoffs-style atmosphere during the season's stretch run.
After race No. 26, the top 10 drivers in points earn a berth in the 10-race Chase. Spots 11 and 12 -- the Wild Card spots ? go to those drivers outside the top 10 with the most wins, provided they are in the top 20. Once the Chase field is set, each driver has his points total reset to 2,000. For those in the top 10, three bonus points are added to that total for each victory during the first 26 races.
