NASCAR Martinsville playoff race 2023: Start time, TV, streaming, lineup for Xfinity 500

The NASCAR Cup Series reaches its penultimate event with a short-track elimination race that will determine the final two championship participants.

Kyle Larson, who won the Round of 8 opener at Las Vegas Motor Speedway, and Christopher Bell, who rallied to win last weekend’s race at Homestead-Miami Speedway, have already secured berths in the championship race. The remaining two spots in the Championship 4 will be decided Sunday at Martinsville Speedway.

The path is simple. If one of the six remaining playoff drivers wins at Martinsville, he will clinch the third spot, and the remaining slot will be awarded to the driver who accumulated the most points in the third round without a win. If none of the six win on Sunday, then both Championship 4 berths will be decided by points.

William Byron, who leads the series with six wins in 2023, enters Martinsville in the best position to capture a Championship 4 spot based on points. Byron has a 20-point lead over the next closest driver in points, Ryan Blaney. At the other end of the spectrum is Chris Buescher, who is 63 points behind Byron, and who must win on Sunday to have a chance to race for the 2023 title.
