Following Brad Keselowski’s victory on Sunday in Las Vegas, NASCAR’s early-season swing through the western United States continues as teams now head to Phoenix International Raceway. There’s another X-FINITY/Sprint Cup Series doubleheader on tap this coming weekend. There are thirty-eight drivers on the preliminary entry list for Sunday’s Good Sam 500, the fourth race of the 2016 Sprint Cup Series. Thirty-five of NASCAR’s thirty-six newly named “Charter” teams have drivers listed, with the driver of the Number-32 Go Fas Racing Ford to be announced. Non-Charter drivers entered at P-I-R are Ryan Blaney, Cole Whitt and Josh Wise.

There have been three different winners with three different manufacturers through the first three weeks of the campaign: Denny Hamlin in a Toyota at Daytona, Jimmie Johnson (Chevrolet) in Atlanta and Keselowski (Ford) at Vegas.

There are thirty-nine drivers on the X-FINITY Series entry list including early-season points leader Daniel Suarez.
