Ernie Irvan took the lead on Lap 410 and held off Rusty Wallace by a car length for his first career Winston Cup victory last night in the Busch 500 at Bristol (Tenn.) International Raceway.

Irvan went in front as Dale Earnhardt tried to get past a lapped car. He led the rest of the way to win $49,600 in the Morgan-McClure racing team's Chevrolet.

Wallace continually tried to get past Irvan in the final laps, but held on to finished second. Winston Cup points leader Mark Martin was third; Terry Labonte was fourth; and Sterling Marlin finished fifth.

"Man, I didn't want to get beat by Rusty at the end," Irvan said. "I made about every mistake I could make and still win the race. It was like an obstacle course out there."

Earnhardt led for 175 laps.

Irvan averaged 91.782 mph on Bristol's steep, .533-mile oval.

Denver Grand Prix: Teo Fabi locked up the pole position for today's Denver Grand Prix by holding off a determined bid by Al Unser Jr. on the downtown street circuit.

Fabi, who won the provisional pole Friday with a lap of 78.760 mph, improved on that speed early in a 30-minute session on the 1.9-mile, 16-turn course, moving up to 78.964.

Unser, the CART-PPG series point leader heading into today's 80-lap, 152-mile event, made a big jump after struggling to seventh place in Friday's time trials. He went from 77.172 on Friday to 78.661 -- finishing the final session three-tenths of a second behind Fabi, who earned his ninth career pole and the third for the Porsche Indy-car team.

Belgium Grand Prix: Brazil's Ayrton Senna, the leader in the Formula One standings, beat McLaren-Honda teammate Gerhard Berger of Austria in the final qualifying session to earn the pole position in Spa-Francorchamps.

Senna earned his sixth pole position this season and the 48th of his career. He is the all-time leader.

The second row will have Alain Prost, in a Ferrari, and Belgium's Thierry Boutsen, in a Renault.

Senna, frustrated by technical problems during Friday's provisional qualifying session, completed the 4.31-mile circuit in 1 minute 50.365 seconds. Berger clocked 1:50.948.
