Johnson, a six-time Sprint Cup champion, led the final 92 laps -- all coming after he had a tire rub that required body repairs on Lap 198 of 500 following contact with Denny Hamlin. The triumph pushes Johnson to the Championship 4 at Homestead-Miami Speedway for the first time since the current Chase for the NASCAR Sprint Cup format began in 2014.
Before the season enters its final three races, let's take a look at what the Chase picture holds after Sunday's race at the short track.
Who's hot: Johnson's dominance at Martinsville should not come has a surprise: He now has won nine times at the "Paperclip." It's his rally that should be commended. He captured the checkered flag after suffering damage that resulted in tire rub early, making the victory somewhat remarkable.
Joe Gibbs Racing continued its strong run in the Chase, with Denny Hamlin, Matt Kenseth and Kyle Busch finishing three-four-five. All three led laps at Martinsville, with Kenseth leading a race-high 176 laps and Hamlin out front for 48 laps. Busch led three circuits.
Busch had trouble keeping up with the leaders from the start, and finished 22nd -- three laps down.
His teammate, Kevin Harvick, earned a pit road speeding penalty on Lap 131 -- when he was running in fourth place. That sent him to the rear of the field, and he never recovered. Harvick finished 20th and two laps down.
But the worst luck of all hit Joe Gibbs Racing driver Carl Edwards, who slammed into the outside wall on Lap 357 of 500 when his right front tire went down. Edwards' No. 19 Toyota suffered enough damage that he went to the garage for repairs, but he was able to return to finish 36th, 23 laps down.
Four in, four out: Here's a look at the Chase bubble, with four drivers being eliminated after the penultimate race of the season, Nov. 13 at Phoenix International Raceway (2:30 p.m. ET, NBC, MRN, SiriusXM NASCAR Radio).
