3: The number of drivers still mathematically alive for the NASCAR Sprint Cup Series championship after Sunday's AdvoCare 500 at Phoenix International Raceway. Five-time champion Jimmie Johnson leads Matt Kenseth by 28 points and Kevin Harvick by 34 as the series heads for Homestead-Miami Speedway and next Sunday's season finale. Johnson can lock up his sixth championship with a finish of 23rd or better, 24th if he leads a lap and 25th if he leads the most laps.
