Today's NASCAR Number is this week's daily double:

20: The number of victories five-time NASCAR Sprint Cup champion Jimmie Johnson has posted in 80 Chase races dating to the introduction of NASCAR's playoff system in 2004. With five wins in last year's Chase, Tony Stewart is second with 11 victories in 80 Chase races, though three of those wins came in 2006, when Stewart failed to qualify for the Chase.

9.0: Johnson's average finishing position in Chase races-not surprisingly, best among all drivers. Stewart is second at 12.5. Johnson also is the runaway leader in laps led during Chase races (3,883), average running position during Chase races (10.129) and driver rating in Chase races (108.7).
