Kasey Kahne passed raced leader Kevin Harvick with 22 laps to go and went on to win today's Sam's Town 300 NASCAR Busch Series race at Las Vegas Motor Speedway. Kahne, driving the Ragu Dodge, was able to pull away from Harvick and Matt Kenseth until a late-race caution on lap 198 necessitated a green-white-checkered finish. Kahne held off Kenseth, who had passed Harvick, to win the two-lap shootout. "We made the right adjustments on the last pit stop and the car was turning the best it had all day," said Kahne. "We were in a great position at the end, but then we had that yellow with 2 laps to go. Matt was good and I knew I had to be good in Turns 1 and 2 on the restart to beat him down the back stretch. Matt was good in 1 and 2, but I beat him down the back straight. I kept telling myself not to make any mistakes." He didn't. "That was the best I could do," admitted Kenseth, who had to settle for second place. "I thought I'd have a shot in Turn 1, down on the white line, but I knew it was gonna be tough to get him. I had a decent restart, but I just couldn't get to him. He was really good in Turn 2." Kevin Harvick finished third. Greg Biffle, polesitter for Sunday's UAW-DaimlerChrysler 400, started third and finished fourth. Carl Edwards completed the top five. The starting lineup was heavily populated with moonlighting NASCAR Nextel Cup Series drivers. Ashton Lewis Jr., driving the Team Marines Ford, was the first full-time NASCAR Busch Series driver across the finish line - in 13th place. The race was not kind to Las Vegas natives and residents. Kyle Busch finished 19th, two laps in arrears of the winner. Spencer Clark started 33rd and finished 35th.. Open-wheel driver Paul Tracy, who resides in Las Vegas, finished 36th. Todd Kluever, driver of the 3M Ford, was the highest-finishing Raybestos Rookie-of-the-Year contender, in 21st place. The race was slowed five times by caution flags for a total of 29 laps. The average speed of the Sam's Town 300 was 125.158 mph (2 hrs., 28 min., 8 sec.). The race was run under unseasonably-cold conditions, with a threat of precipitation, temperatures in the mid-40s and a track temperature of 50. SAM'S TOWN 300 FINISH: 1. Kasey Kahne, 2.
