Further back, Kyle Busch had been powering through the backmarkers to 12th place after qualifying in the 34th spot, but it was clear that trouble lay in store for him: Kevin Harvick was conspicuously stalking him over the race track, repeatedly crowding him as they battled for position and then later following Busch to the inside and staying glued to the #18's bumper. NASCAR told both teams to stop fooling around and concentrate on the racing, which infuriated Busch.
"The #29 is all over me!" Busch retorted, and his crew chief Dave Rogers sought to calm his driver down by agreeing. "Keep your composure in that race car, bud," Rogers replied; "I've lost mine about four times already."
When Harvick backed off, it seemed that the word had gone out to his team mate Jeff Burton to take over: clearly the Richard Childress Racing team were carrying on their boss's vendetta with Kyle onto the track. "He knows he has one coming," Harvick told ESPN.com. "I just wanted him to think about it."
Busch, though, was trying to keep away from all the mind games and resisted being lured into retaliation. "I was running my own race – it was another car I had to pass," Busch said after the finish."Seemed like he was trying to make it awfully difficult on me. There's a couple times where I just had to back off and wait, got back to him and tried to pass him again ... Maybe kind of shows his character and who he is, how he feels he needs to race on the racetrack," Busch said of Harvick's aggression. "But it's not my fight. He's trying to turn it into one."
Once NASCAR handed the warning to everyone involved, the feud simmered down and racing got back to the business at hand; Harvick himself ended up on pit road early after failing to get a full shot of fuel during his previous stop, which helped put some track distance between #29 and #18.
Before the green flag pit stops came around on lap 47, Hamlin's lead had grown to almost 4s ahead of Juan Montoya and Kurt Busch, with Carl Edwards, Dale Earnhardt Jr., Jimmie Johnson and Jeff Gordon closest to him. Hamlin quickly picked up the lead again after the stops cycled through and continued to lead for the next 27 laps with only Juan Montoya managing to hold on despite his two-tyre gambit as Hamlin stretched his command of the race; Kurt Busch by contrast was fighting a loose #22.
Pretty soon Carl Edwards was not among those in pursuit: he took the #99 onto pit lane on lap 60 reporting that the car's engine had a terminal problem. "One of the valves got in an argument with something in the engine and lost," Edwards explained. "We broke one valve. We don't think it was from an over-rev or anything. We just think it was a parts failure."
He said it didn't seem to be related to the return of the need for drivers to shift gears during the Pocono event, following that change NASCAR made to gear ratio settings for the race. "No, I don't think that had anything to do with it. I was trying really hard to be easy on the engine and only shifting in one and two and I was short shifting into fourth. I didn't want to over rev it."
Edwards' retirement would have major consequences for the Sprint Cup championship. He'd arrived at Pocono walking away with the lead by 40pts, but afterwards his lead would be slashed to just 7pts following his classification in 37th place here. "That is racing I guess. What good is the point lead if you don't use it? We are using it today and we are going to need every bit we can to get out of here with the lead today."
While Edwards wondered off and took up residence as an unexpected addition to the TNT commentary team, among others failing to make race distance were Sam Hornish Jr. - returning to Cup racing for the first time this year - and Marcos Ambrose.
