BROOKLYN, Mich. -- Look out Kyle Busch, here comes Carl Edwards.
Edwards completed a weekend sweep at Michigan International Speedway on Sunday, beating NASCAR Sprint Cup points leader Busch off pit road on their last stops and driving off to his fifth Cup win of the season and second in the last three races.
Busch, who has eight Cup wins, was just ahead of Edwards when they pitted under caution on lap 180 of the 200-lap 3M Performance 400, but Edwards beat the 23-year-old star out of the pits.
David Ragan and June Michigan winner Dale Earnhardt Jr. had stayed on track and were running 1-2, but Edwards easily passed them on the restart on lap 183 to retake the lead, then held off Busch on another restart with two laps to go and gave Roush Fenway Racing co-owner Jack Roush his 20th overall victory on the 2-mile Michigan oval.
Edwards, who turned 29 on Friday, also won the Nationwide Series race Saturday, becoming only the second driver to win both races. Former Roush driver Mark Martin did it in 1993.
"The key was my crew today,'' Edwards said. "My guys did an unbelievable job getting me off pit road.
"This is unbelievable. We're winning races. We're gearing up for the Chase. I'm feeling stronger than ever. We're here to win championships. That's what we're shooting for.
With just three races left until the start of the Chase for the championship, Edwards moved a little closer to Busch in the seeding process, which gives drivers making the 10-race postseason a 10-point bonus for each victory.
Edwards lost one of those 10-point bonuses to a penalty early in the season, but would still be just 40 points behind Busch if the Chase began next week.
"That's a part of it,'' Edwards said. "Ten points is 10 points. The beauty of it is keeping Kyle from getting 10 points. He's so fast you can't give him any room.''
Edwards was pulling away at the end, building a lead of nearly 1.5 seconds before Denny Hamlin's blown engine brought out the seventh and final caution flag of the day on lap 195 of the 200-lap event. That moved Busch's Toyota right up to the rear bumper of Edwards' Ford as the green flag waved for the final time for the start of lap 199, but it wasn't close as Edwards pulled out to a 15 car-length victory.
"It was a decent run for us,'' Busch said. "We just didn't have enough for the (No.) 99 there at the end. We weren't able to get through the corners as fast as Carl was.''
Asked about the championship, Busch said, "Carl's right there. He has been all year. Yeah, it's a 20-point swing. We've got to live with it. Hopefully, we can make it up someplace else.''
Ragan held on to finish third, followed by Roush Fenway teammates Greg Biffle and Matt Kenseth, who bounced off the wall passing Martin, now driving a Chevrolet for Dale Earnhardt Inc., on the last lap.
