Phoenix International Raceway – also known as PIR – is a one-mile, low-banked tri-oval race track located in Avondale, Arizona.

The motorsport track opened in 1964 and currently hosts two NASCAR race weekends annually.

The raceway was originally constructed with a 2.5 mi (4.0 km) road course that ran both inside and outside of the main tri-oval.

For this specific race, positions 21-40 would be decided on time,[3] and depending on who needed it, a select amount of positions were given to cars who had not otherwise qualified but were high enough in owner's points; which was two for cars in the NASCAR Winston Cup Series and one extra provisional for the NASCAR Winston West Series.

Sterling Marlin, driving for Morgan–McClure Motorsports, would win the pole, setting a time of 27.728 and an average speed of 129.833 miles per hour (208.946 km/h) in the first round.
