With Kasey Kahne’s win in the Brickyard 400, there are now only four open spots on the 16-driver playoff grid.
There are six races left in the regular season. Any spot not filled by a new winner will be filled based on points.
If Joey Logano’s win at Richmond was not encumbered due to failing post-race inspection, there would only be three spots left.
Kyle Busch is the highest-ranked driver without a win. He is fourth in the standings, 107 points back from leader Martin Truex Jr.
The other top drivers without wins are Jamie McMurray (-181), Chase Elliott (-192), Matt Kenseth (-214).
