Logano boosted his chances of reaching the Chase for the Sprint Cup, winning for the first time this season in a fuel-mileage race at Michigan International Speedway on Sunday.
Logano and Kevin Harvick both breezed past Mark Martin with just over three laps to go in the 400-mile, 200-lap race. Martin had been trying to stretch fuel, but when he faltered, Logano was able to hold off Harvick.
The win put Logano in 13th place in the standings. He's seven points behind Martin Truex Jr. for the second wild card.
It's been an up-and-down year for Logano. He and teammate Brad Keselowski were docked 25 points each after NASCAR inspectors confiscated parts from the rear suspensions of their cars before the April 13 race at Texas.
More recently, Logano has had to recover from back-to-back 40th-place showings at Daytona and Loudon, but he's now right in the middle of a wild race for the final Chase spots.
"A roller coaster, to say the least," Logano said. "We've just got to keep that momentum going. It just goes to show, as long as nothing goes wrong knock on wood we've been pretty good. We've had some good speed in our cars."
Everything went pretty much according to plan at Michigan. Logano won the pole Friday and took Sunday's race by a second over Harvick, who is safely in fourth place in the standings.
"I was very pleased with the day," Harvick said. "It's just going to come down to getting on a hot streak over 10 weeks and not making any mistakes."
There are three races left before the Chase. Keselowski, the defending champion, is still in eighth place with 667 points, but Kurt Busch is now only two points behind him after a third-place showing Sunday. Greg Biffle (663) is in 10th place. Kasey Kahne (659) and Truex (653) are in line to be the wild cards, but Logano closed a lot of ground.
Points leader Jimmie Johnson lasted less than 60 laps Sunday before engine trouble knocked him out. He still has a 41-point lead over Clint Bowyer.
