Dover, Del. ? Scott Wimmer used a quick stop to beat Mike McLaughlin off pit road during a late caution in the NASCAR Busch series race Saturday and drive to his first career victory.

Wimmer was third after a four-car crash that involved points leader Greg Biffle on the 139th of 200 laps in the MBNA All-American Heroes 200 at Dover International Speedway.

Two laps later, Wimmer’s Pontiac easily beat McLaughlin’s Pontiac and defending champion Jeff Green’s Chevrolet off pit road. Then the 26-year-old driver from Wausau, Wis., pulled away and was not threatened again.

“We’ve been practicing pit stops, and these guys keep getting better and better,” Wimmer said.

Wimmer, in his second full season on the circuit, won in his 63rd career start. McLaughlin, a former winner at The Monster Mile, wound up second.

Wimmer averaged 118.266 mph in a race slowed four times by cautions covering 19 laps.
