– Kyle Busch punched his ticket into NASCAR's championship race with a victory in overtime of a race at Martinsville Speedway that ended with a multicar accident after Busch took the checkered flag.

Busch moved Joe Gibbs Racing teammate Denny Hamlin out of his way to earn a spot in next month's championship race at Homestead-Miami Speedway for the third consecutive year. Martin Truex Jr. was second.

"We weren't the best all day, but we put ourselves in the right spots there at the end," Busch said.

Brad Keselowski was in position to win when Joey Logano developed a tire problem with about 10 laps remaining in regulation. Had Logano pitted under green to fix the tire, Keselowski likely would have won easily and earned the spot in the finale.

Instead, Logano spun and brought out a caution.

Keselowski was moved out of the way by Chase Elliott after a restart, and Hamlin then spun Elliott out of the lead with two laps remaining in regulation. Elliott wrecked, chased Hamlin down on the cool-down lap, and the drivers had a heated exchange after they climbed from their cars. Elliott went from potential race winner to 27th.
