Low qualifier Mike Salinas decided to reward his crew after his breakthrough Top Fuel win in Las Vegas. He brought them all on stage and handed them folded t-shirts, telling them that if their shirt had a Harley-Davidson logo on it, they would win a new motorcycle. Much to their surprise, all of the shirts had the logo.

Dom Lagana. who didn't make a full pass in three qualifying tries, found the magic in round one and was one of eight drivers to advance to the semifinals.

Funny Car legend John Force, still looking for career win No. 150, had low e.t. of the first round to advance.

Doug Kalitta, who had reached the final round in four of the previous seven four-wide events, got out of round one but was stopped in the semifinals.
