The fourth race of the NASCAR Xfinity Series season takes place at ISM Raceway. Putting on a good showing in Phoenix is a big deal to Xfinity Series teams as they will return to this racetrack near the end of the season.
Las Vegas winner Kyle Busch will be competing in this event in the iK9 No. 18 and the task for the rest of the field will be finding a way of preventing him from going to victory lane.
The Xfinity Series race at ISM Raceway will take place at 4 pm ET on FS1 and MRN radio.
