Pennsylvania International Raceway, later known as Nazareth Speedway, hosted its first IndyCar race on a paved track in 1987, as local favorite Michael Andretti won the Bosch Spark Plug Grand Prix, the third to last round of the season. He’d fail to make up much ground to his chief championship rival, however, as points leader Bobby Rahal followed him to the finish line. Team Penske driver Rick Mears would complete the podium.

Al Unser, returning to the field as an injury substitute for Roberto Guerrero, would run as high as second late in the race before touching wheels with Jeff MacPherson in the race’s final laps. The race ended under caution as an upset Unser watched from the sidelines.
