Martin Truex Junior dominated Dover’s “Monster Mile” on Sunday, storming into the second round of the Chase with his fourth win of the year and second in three weeks of post-season competition. Truex started second and led a race-high 187 laps in notching his seventh career victory and second at Dover International Speedway. His lead grew to nearly ten seconds during the second half of the race and the final margin of victory over runner-up Kyle Busch was seven-point-five seconds. Rookie Chase Elliott finished third with pole sitter Brad Keselowski and Matt Kenseth completing the top five. Chase contenders grabbed nine of the top ten finishing positions with Jeff Gordon riding home in tenth place subbing for Dale Earnhardt Junior. There were just five drivers running on the lead lap with Truex at the checkered flag … Sunday’s race was the final stop in the opening round of the post-season Chase for the NASCAR Sprint Cup. Three-time champion Tony Stewart finished thirteenth, but it wasn’t enough to prevent elimination. He joined Chip Ganassi Racing teammates Kyle Larson and Jamie McMurray, and rookie Chris Buescher in being dropped from title contention. Buescher finished twenty-third on Sunday, Larson twenty-fifth and McMurray fortieth. Larson, at Number-10, was the highest-seeded driver in that quartet … In finishing second on Sunday, Busch – the top seed in the post-season Chase – led three times for 102 laps … Kenseth was looking for a season sweep at Dover after winning there in mid-May but fell short, settling for fifth place.
