Kyle Larson retook the Cup points lead from Martin Truex Jr. with his victory Sunday at Michigan International Speedway, but the Chip Ganassi Racing driver lost ground to Truex in another important category.
Truex, who finished sixth and dropped five points behind Larson, increased his series-leading playoff points total to 20 with two stage wins at Michigan. He is five points ahead of Jimmie Johnson and seven in front of Larson in the playoff standings. Those points will carry through the first nine races of the playoffs.
Truex has a series-high 10 stage victories this season, four more than second-ranked Kyle Busch.
The regular-season champion will be awarded 15 playoff points (five more than the runner-up), so Larson still can gain ground on Truex by maintaining the points lead through the first 26 races.
