Video: Chastain rides the wall to make Martinsville Playoffs

Ross Chastain picked Lap 500 to turn the NASCAR Cup Series’ fastest lap in the history of Martinsville Speedway. And true to the form of Trackhouse Racing’s reputation as disruptors in its brief existence, this latest master stroke from the journeyman driver came through unconventional means with some of the highest stakes possible riding on it.

It was straight video-game stuff that decided the final spot in the Championship 4 field for Chastain, who leaped from 10th to fifth place in a wall-riding dash through Turns 3 and 4 at the end of Sunday’s Xfinity 500. The holiest of Hail Marys pushed Chastain from a one-point deficit to a four-point edge over Denny Hamlin for the last title-eligible berth in next Sunday’s season finale at Phoenix Raceway.
