CONCORD, N.C. -- Greg Biffle began an 800-mile day by winning the rain-postponed Busch Series race at Lowe's Motor Speedway on Saturday with the season's largest margin of victory.
The Little Trees 300 was scheduled for Friday night, but was delayed by bad weather. So it started eight hours before the Winston Cup race -- and Biffle was one of 11 drivers entered in both.
Biffle, the Busch champion last season, beat Michael Waltrip to the finish by 12.628 seconds.
It was his 10th career Busch win and first since August 2002.
"These guys do a fantastic job. We've just really started to get ourselves going here lately," said Biffle, who has been substituting frequently in Evans Motorsports' No. 7 Chevrolet since the team released driver Randy LaJoie in June. "This car was on the rail all day."
Others
Mike Bliss finished third, Brian Vickers fourth, and Jamie McMurray fifth. Everyone in the top five except Bliss was scheduled to run in the Cup event, including Vickers, who was to make his Winston Cup debut.
Series points leader David Green was sixth and holds a 36-point advantage over Vickers with five of 34 races remaining.
Pole winner Kevin Harvick, who shares driving duties with Johnny Sauter in Richard Childress Racing's No. 21 team, finished ninth. The No. 21 team holds a 156-point advantage in the chase for the series' car owner championship.
Of the 11 Winston Cup drivers scheduled to compete in both races, only series points leader Matt Kenseth opted out.
Kenseth, who has lost 177 points the past two weeks and now leads Harvick by just 259, decided Saturday morning to let Jeff Burton drive in his place.
NASCAR Trucks
FORT WORTH, Texas -- Brendan Gaughan came from the back of the pack and won Saturday at Texas Motor Speedway, becoming the first NASCAR truck driver to win four straight races at the same track.
Gaughan was forced to drop to the back of the 36-truck field to start the Silverado 350 because of an engine change before he qualified seventh. He didn't stay there long, even after having to repair some early fender damage.
By the 28th lap, Gaughan had already moved up to 16th in his Dodge aptly named "Lone Star." He went in front for the first time on the 77th lap after picking off truck after truck on the outside line, mainly in the high banking of Turns 1 and 2.
Six cautions
Gaughan beat Travis Kvapil's Chevrolet by 1.905 seconds with an average speed of 122.727 mph that was slowed by six cautions for 29 laps. He led three times for a race-high 60 laps, including the last 43 of the 146-lap race.
Ted Musgrave finished third in his Dodge. He remained third in points, but dropped from 58 to 73 points behind Gaughan.
