Already we were seeing good progress for Jimmie Johnson (recovering from a poor qualifying position that saw him start from 28th), AJ Allmendinger, Jeff Gordon and Brad Keselowski who gained four spots in the ensuing pit stops under caution. Less happy were Juan Montoya and also Kevin Harvick, who seemed stuck going nowhere at the bottom of the top 20.
But without a doubt the man having the worst of things was Kyle Busch who had a scare with the wall on lap 9 and then took two visits in pit lane under the caution - once for major set-up changes, the second for four tyres - that put him to the back. "We made some big changes there on that pit stop," he explained. "We came back and got four just to make sure we got all the changes we wanted to."
Despite all that work he seemed no happier in the next green flag stint, and on lap 59 his right front tyre blew and the #18 headed into the wall at turn 2 to bring out the second caution of the day. "Just blew a bead, I guess, transferring too much brake heat through the wheel," he said, referring to the tyre edge.
He denied that the crash had been due to any contact with Dale Earnhardt Jr.: "Nice try at making up a story," Busch replied. "There's contact with everybody out there. It had nothing to do with anybody else ... Nothing else besides that." The repairs to the car took some 76 laps and meant that Busch would finish in 36th place, dropping from the lead of the Cup points standings to fifth some 20pts off the new leader as a result.
In the meantime, Jamie McMurray had briefly led the race before being ousted by Newman, but it was really Kurt Busch who took charge between the two yellows. After Busch's crash it was Mark Martin who led the restart on lap 65, but once again Newman was quick to take charge again with Tony Stewart slotting back into second place through to the third caution (for debris) on lap 100.
Jimmie Johnson opted to stay out of pit lane for temporary track position while those that did come in opted mainly for two tyres, which did not seem to suit the Stewart-Haas duo nearly as well at this point and they slipped back, allowing Jeff Gordon, Jeff Burton and Kasey Kahne to take up the top three positions as Johnson started to fade on worn rubber and eventually come in for an off-sync green flag stop on lap 135.
Gordon's lead was all the more impressive given that his #24 was having battery problems and was nonetheless the fastest car on the track during this midrace stage. "We knew we were losing the power to the engine from an alternator standpoint," he said. "These new gauges have warning lights on them that the whole gauge lights up." The problems meant he had to shut down the cooling system, including the cooling to the brakes.
Surprisingly Gordon opted not to switch out the twin batteries at the next round of stops that took place after Brad Keselowski cut a tyre in turn 3 on lap 144, a particularly useful caution for Jimmie Johnson as it gave him a much-needed wave around. Gordon would rue the decision to risk the batteries when he lost all power shortly after the restart on lap 154 and dropped to the back of the lead lap; he was saved when a rapid fifth caution materialised for debris on lap 161 allowing him to come in for the battery exchange under yellow.
Kurt Busch had taken the lead during the previous round of pit stops and kept it despite a strong challenge at the restart on lap 169 from Brian Vickers, but the race was quickly back under yellow with the sixth caution of the day after Denny Hamlin got helped into a spin by AJ Allmendinger. Again, the main beneficiary of the caution was Jeff Gordon, who got the lucky dog back onto the lead lap after his lengthy battery exchange pit stop.
Busch was still leading at the restart on lap 174 and this time the green flag racing lasted only ten laps before Mark Martin spun out of 14th position with a cut tyre in turn 2. Kurt continued to lead at the restart on lap 189, but Tony Stewart was now awake again and charging, passing Carl Edwards for second on lap 191 and then taking the lead from Busch down the inside on lap 194, his team mate Ryan Newman not far behind in fourth.
