Race recap

The race began under cold and windy conditions that caused tire problems, which resulted in two accidents occurring immediately after pit stops. Greg Ray slid into the wall in turn-2 on lap 38, and about 25 laps later Sam Schmidt spun coming out of turn-2 and hit the wall. Buzz Calkins and Jack Miller both ran into debris from Schmidt's car, and all three were out.

Pole sitter Billy Boat did not stay up front very long; Jeff Ward quickly took charge until he began having engine problems and then Mark Dismore moved into the lead. Affonso Giaffone took the lead on lap 100, but during a pit stop on lap 116 a wheel was not tightened properly and it came off as Giaffone pulled back onto the track, damaging the suspension and undercarriage. Giaffone would finish, but well back.

Several drivers then dueled for the lead until Salazar took over; the veteran driver led most of the rest of the way and survived a two-lap sprint with Scott Goodyear after a late caution to win. The caution occurred when Roberto Guerrero touched wheels with a slower car and suffered a frightening accident; the car became airborne and then barrel-rolled through the infield grass on the backstretch. It was the first time an IRL car had been upside down during a live run, and the safety systems worked as planned: Guerrero walked away with minor injuries.

Both of the championship contenders, Stewart and Davey Hamilton, had problems; Stewart won the title owing to the points lead that he had coming in. This race marked the first competition for the new Riley & Scott chassis, with Stan Wattles taking one to an eighth-place finish. Eliseo Salazar took home his first IRL victory as Tony Stewart clinched the 1997 championship.
