Vote now: Who will win the NCWTS race at Phoenix?

Now's your chance to make your voice heard in the latest FOXSports.com NASCAR poll question. We're asking who you think will win tonight's Truck Series race at Phoenix.

The NASCAR Camping World Truck Series will decide the final three spots for the Championship 4 at Homestead-Miami Speedway tonight in the Lucas Oil 150 at Phoenix International Raceway.

Only Johnny Sauter, who has won the last two Truck Series races, has his spot locked up in the championship race. There are five drivers competing for one of the final three spots.

William Byron currently has the most points among the five drivers but a win would take all of the math out of the equation to keep his championship hopes alive.

His Kyle Busch Motorsports teammate, Christopher Bell trails Byron by one point, so if he isn't heading to Victory Lane, a good finish will move him on to Homestead.

Matt Crafton currently holds the final transfer spot by one point over last year's Phoenix winner, Timothy Peters.

Ben Kennedy brings up the bottom of the Chase grid after having disappointing results in the last two races. He'll be focused on grabbing the checkered flag to take away having to hope some guys in front of him have bad luck.

There's also a chance that one of the drivers outside of the championship competition can come in and steal the show.

Cast your vote below and check back before the race starts for the results. The action from Phoenix can be viewed tonight on FS1 at 10:00 p.m. ET.
