Jimmie Johnson overtook title rival Brad Keselowski in a green-white-chequered finish to claim his fifth win of the NASCAR Sprint Cup season on Sunday at Texas Motor Speedway.
Five-time champion Johnson, who had led nearly half the race distance before the final green flag, drove around the outside of Keselowski with one lap remaining.
That followed a close battle at the previous restart where the Penske racer managed to remain ahead while resisting a fierce, fender-banging, attack from the Chase leader.
Keselowski's #2 Dodge had emerged up front from the final round of stops after crew chief Paul Wolfe made the call to change two tyres while the rest of the leaders took on a full set for the last 21 laps.
This attempt to make the most of clean air initially paid off but Johnson's final attack, squeezing Keselowski on the inside at Turn 1 to get him loose, sealed back-to-back wins that allowed him to extend his championship lead.
In the process Johnson gave Chevrolet its 700th Cup win a week after helping deliver yet another manufacturers' title for the bow tie brand with his Martinsville victory.
Keselowski, who put on his best performance ever at the mile-and-a-half track, believed the final restarts gave Johnson a shot at his lead but reckoned his two-tyre change would have probably cost him in a longer green-flag run as well.
"I think the restarts made the difference," said Keselowski. "Jimmie probably would have got me with an extended amount of laps to go. But with only five or six to go when we had the lead, I felt pretty good about it.
"But getting that last yellow, I felt like restarts are like rock, paper, scissors. Eventually you're going to lose them. It's just a matter of time. There's always time to counteract the strategy. To win two out of three, I felt lucky to do that. Obviously, I didn't win the last one that counts."
Joe Gibbs Racing's Kyle Busch was the only other car able to keep up with the leading title contenders, though ultimately he was only watching from behind as the duel unfolded in front of him. Busch complained about Keselowski's restarts in the decisive stages.
"I think Brad went early the last two times," said Busch. "From my vantage point, anyway, from compared to where the line starts you're supposed to go within the zone, and I felt like he was a little early on that... But from my experience with Brad, it doesn't surprise me."
Roush Fenway's Matt Kenseth finished fourth ahead of reigning champion Tony Stewart and Michael Waltrip Racing's leading title contender Clint Bowyer, who lost ground in the final stops after running among the top five for most of the distance.
He has dropped 36 points behind Johnson in the standings as a result while Hendrick's Kasey Kahne is now a distant 58 points adrift from the Chase leader after finishing a lapped 25th.
