Entering the final race in the Round of 8, all four spots in the Championship 4 at Homestead-Miami Speedway are still up for grabs.
Sprint Cup Series drivers won the first two races of the round at Kansas and Texas. It leaves open the opportunity for one Xfinity Series Chase driver to earn their way to Homestead via a win at Phoenix, while three others could be decided on points.
With seven Sprint Cup drivers entered in the race, there is also the possibility that all four spots will be earned on points.
The four drivers advancing to the championship-deciding race will be determined Saturday night in the Ticket Galaxy 200.
