Many of the names you'd expect to be there, are.
You've got former champions like Jimmie Johnson, Brad Keselowski, Kurt Busch and Kevin Harvick. The talented quartet of drivers with Joe Gibbs Racing are all in the fray. Smoke will be looking to set the Chase on fire in his final season. Joey Logano, Martin Truex Jr. and Jamie McMurray are also all making return trips to the Chase for the Sprint Cup.
But four drivers, including two rookies, will be making their postseason debuts this Sunday in Chicagoland. Let's take a look at some of the young stars gunning for their first taste of success, starting with Chip Ganassi Racing's Kyle Larson:
Kyle Larson comes into the Chase on fire. Following up his first career win at Michigan, the No. 42 driver had a third place showing at Bristol before racing his way to second place finish in the regular season finale at Richmond. Larson was sitting ninth coming out of the final caution, but weaved his way seven spots through the field in the final laps to a career-best finish at the Action Track.
A NASCAR Next graduate, Larson has been on the postseason cusp since his 2014 rookie campaign. So while this might be the first Chase appearance for the California kid, you can bet it won't be his last.
