Mario Andretti retained the pole for today's U.S. Grand Prix at the Meadowlands by virtue of his first-day qualifying speed, and Danny Sullivan withdrew one car and still secured the other front-row starting spot.

The pole for Andretti was his third of the season, 11th in his last 21 tries and the 53rd of his career, tying the Indy-car record set by A.J. Foyt.

"The clear advantage of being on the pole at a circuit like this is to set the pace at the start of the race," Andretti said of the 1.68-mile, 11-turn circuit. "The fewer cars you have around you, the better."

Sullivan retained the second qualifying spot by driving his March 85C Miller American racer to a fast lap of 97.015 mph. Sullivan was forced to go to his backup after an engine problem developed in his No. 1 car.

Meanwhile, two drivers were treated for injuries incurred in the Meadowlands Kelly American Challenge Twin 45s, a road racing stock car competition.

Paul Gentilozzi of Lansing, Mich., broke his right ankle when he hit the wall. He will remain in Hackensack (N.J.) Hospital overnight. Carson Hurley of Pleasant Garden, N.C., was treated for a concussion, then released.

Irv Hoerr won the race by two seconds over Dick Danielson. Defending champion Tommy Riggins was third.
