Mark Martin continued his improbable comeback with his third victory of the season, which was won on a thrilling third-to-first finish in the final two laps of the LifeLock 400 at Michigan International Speedway. Martin was in third place when leader Jimmie Johnson, who had dominated the race, ran out of gas. Greg Biffle passed Johnson, but Biffle ran out of gas himself and Martin passed him and coasted to the finish line for the win.

"I went for the points," Martin said. "I thought those guys were running too hard for us to save gas. I couldn’t do both – save gas and run with them. When Jimmie ran out … I said, ‘Heck, we’re this close. I’m going to run hard.’"

Jeff Gordon, who started 43rd, finished second. He was followed by Denny Hamlin, Carl Edwards and Biffle. Johnson finished 22nd.

In the Chase standings, Tony Stewart, Jeff Gordon and Jimmie Johnson stayed 1-2-3. Kurt Busch passed Ryan Newman for fourth. Mark Martin jumped back into the top 12 at the eighth spot. Hamlin moved up to 10th. Matt Kenseth fell back to 11th and Jeff Burton fell to 12th. David Reutimann fell out of the top 12, to 13th.

Dale Earnhardt Jr. finished 14th in the race and is 18th in the Chase standings.
