Harvick was running third late in the race when Jimmie Johnson hit the wall trying to run leader Greg Biffle down, which allowed Harvick to move into second.
"It's just one of those days where you had to survive. You had to try to keep your track position the best that you could. You had to manage tires and get them on the car because people were having a lot of trouble," Harvick said.
"So, it's definitely one of those races where you had to manage numerous amounts of things to keep yourself in it."
While leading the race on Lap 104, Kahne's right-front tire blew out and he slammed hard into the wall in Turn 2, bringing an end to his race. Last weekend at Pocono, Kahne was forced to the garage at the start because of a broken U joint that had to be replaced.
"I had no indication. We were just cruising," said Kahne, who dropped to 12th in points. "I knew it was going to be a battle with Jimmie (Johnson) today. He's fast and I thought we were really good."
Gordon got collected in a wreck on Lap 7 when Bobby Labonte spun in front of him. Gordon finished
"I'm a pretty patient person, but it's testing my frustration level and my confidence that is the biggest thing. We all know how big confidence is in this sport, any sport really, Gordon said. "I don't want to see the team get down and I don't want to see myself get down."
Stewart moves into Top 10: It was just a month or so ago many wondered if Tony Stewart would qualify for the Chase. After his fifth place finish on Sunday, Stewart has now moved into the Top 10 in points for the first time this season.
Stewart hasn't finished worse than seventh in his last four races and gained 11 spots in the series standings during that span.
