At 3:35 p.m., the track was dried, and qualifying resumed. Five more cars were able to take to the track, but rain returned, and the track was closed for the day at 4:20 p.m. The field was only filled to 15 cars, and several drivers, including Mario Andretti and Gordon Johncock were still in line and eligible for the pole. Al Unser and Johnny Rutherford, however, both suffered blown engines during the day, and had to forfeit their spots in the qualifying line. Both would be ineligible for the pole, and would have to be second-day qualifiers.
