Kyle Busch claimed back-to-back victories after upstaging Chase Elliot at the NASCAR Apache Warrior 400 on Sunday.
With five laps remaining at Dover on Sunday, it looked like Elliott was finally going to end a 69-race winless streak to begin is career, but Busch had other plans.
The Son of Hall of Famer Bill Elliott, and heir to Jeff Gordon at Hendrick Motorsports, Chase led 59 of the final 61 laps in the first cut-off race of the postseason, however Busch was able to get by the number 24 with two laps remaining and hang on for his second straight triumph.
Kurt Busch, Kasey Kahne, Ryan Newman and Austin Dillon failed to advance in the playoffs as the 16-driver field was reduced to 12 following the race.
Jimmie Johnson finished third, followed by Martin Truex Jr. and Kyle Larson.
After another three races (in Kansas on October 22), four more drivers will be eliminated based on points, and then again in Phoenix on November 12 until four drivers remain.
All points except playoff points will be reset before the Round of 12 begins next Sunday in Charlotte, and then again before the Round of 8. The Championship 4 drivers will race straight up at Homestead-Miami Speedway for the title.
Dale Earnhardt Jr., making his final appearance as a full-time driver at the Monster Mile, finished seventh, his best placing since fifth at Texas earlier this season. Junior has yet to win a race in his final season and will look to next Sunday's race at Charlotte to end the streak.
