It's playoff time in NASCAR as the Chase gets underway outside "The Windy City."

FOX News Radio's Rich Denison gives you the lowdown in this week's "FOX in the Fast Lane":

NASCAR's Sweet 16, kicks off the Chase for the Sprint Cup trophy at Chicagoland Speedway for the first of three challenger races.

The rules are simple... Win and you're in... As a trip to victory lane automatically sends a driver to the next round.

Matt Kenseth is the fourth seed entering the Chase with four wins this season in his No. 20 Toyota, and he knows "W's" aren't easy to come by in post-season.

(Kenseth) "You have to have things go right, you know, if you don't get a win... the way the point season is... there's only three races, you have one bad race -- it's hard to dig out of that particularly as you get farther into the Chase if you're fortunate enough to keep advancing."

Driver Brad Keselowski is the ninth seed and hopes past success at Chicagoland can lead to a checkered flag on Sunday

(Keselowski) "We're gonna try to make the most of it early in the Chase and hopefully get an early win in to not have to sweat weeks two and three in Lauden and Dover."

Six-time champ Jimmie Johnson is the top seed in the Chase.
