Today's NASCAR Number is this week's daily double:
4: The number of times Jimmie Johnson has come to Homestead-Miami Speedway with the lead in the Chase for the NASCAR Sprint Cup. Johnson topped the standings in 2006, 2007, 2008 and 2009.
4: The number of times Johnson has won the NASCAR Sprint Cup Series title after leading the series entering the season finale. Johnson closed the deal in each of the years listed above. He won his fifth title in 2010 by coming from behind to overtake Denny Hamlin in the final race. Johnson holds a 28-point lead over second-place Matt Kenseth entering Sunday's Ford EcoBoost 400 at Homestead.
