The second stage ended at Lap 250 of the 500-lap race.
It is Kenseth’s third stage win of the year. He entered the race holding the final playoff spot.
Jimmie Johnson finished second. Kevin Harvick placed third, Ryan Newman was fourth and pole-sitter Erik Jones finished the stage fifth. Jones was followed by Kyle Larson, Denny Hamlin, Busch, Paul Menard and Clint Bowyer.
Busch controlled most of Stage 2 and seemed set to win it until crew chief Adam Stevens elected to pit for tires to help set the team up for the rest of the race.
Busch fell from first to sixth on a pit stop after winning Stage 1 because of a problem with the left rear tire. He worked his way back to the lead on Lap 167, passing Jones for the top spot.
Jones took the lead back on Lap 179 as they raced in traffic around Brad Keselowski, who lost four laps because of a cut left front tire from contact in the opening laps.
Busch regained the lead on Lap 199. He maintained the advantage on pit road shortly after that when Ricky Stenhouse Jr. hit the wall and brought out the caution.
Martin Truex Jr. had a loose right rear wheel and pitted as the field took the green on the restart. He had to pit shortly after that when he was penalized for an outside tire violation. After serving the penalty, Truex was two laps behind the leaders.
AJ Allmendinger had to pit under green because he had a tire rub after contact.
Jeffrey Earnhardt and Austin Dillon crashed on Lap 232. Dillon spun up the track and Jeffrey Earnhardt had nowhere to go and slammed into Dillon’s car. Kasey Kahne hit the wall and Joey Gase‘s car as he tried to slow.
