Team owner Roger Penske attempted to defuse assertions by Brad Keselowski that his organization has been unfairly scrutinized in the past week by NASCAR, culminating in an unspecified violation identified by officials in a standard inspection moments before the green flag dropped on the NRA 500 on Saturday.Crews for Keselowski, the defending Sprint Cup champion, and Penske Racing teammate Joey Logano found themselves scrambling after inspectors ordered the confiscation of rear-end housing parts and pieces on both cars, requiring hurried modifications to the Fords in the garage area at Texas Motor Speedway.Penske said inspectors “didn’t like something in the rear axle.”“So they made us take it out,” Penske said. “NASCAR has a job to do. We’re competitors. Obviously, we’re trying to get an edge on the competition so our guys are thinking and working hard.“You saw how well we ran without it. So to me it’s a closed case.”Both drivers were allowed to start at their predetermined posts — Keselowski at 16 — and their crews allowed to remain, though Logano was ultimately pushed to the back because he was late to the starting grid after his crew failed to make a timely fix.Logano, in the No. 22, rebounded well, finishing fifth behind Carl Edwards and Greg Biffle, Roush Fenway Racing teammates who came in third and and fourth.Keselowski rallied in the No. 2, surging past Kasey Kahne and Matt Kenseth for ninth, bolstering his No. 2 ranking in the Sprint Cup Series standings with a second consecutive top 10 at TMS.“I have one good thing to thing to say and that was my team and the effort they put in today in fighting back with the absolute [expletive] that’s been the last seven days in this garage area,” said Keselowski, who did not elaborate.“The things I’ve seen over the last seven days have me questioning everything I believe in. I’m not happy about it. I don’t have anything positive to say, and I probably should just leave it at that.”Penske officials will await any punitive measures handed down by NASCAR. Those could include a subtraction of points, fines and crew suspensions.“Whatever NASCAR does we have to deal with it and move on,” Penske said.The incident did nothing to lessen Logano’s growing reputation as a bad boy.In March, he was involved in an accident that resulted from aggressive side-by-side racing that knocked out Denny Hamlin for several weeks with a fractured spine.To make matters worse, he and Hamlin had been sparring on Twitter since Daytona. Other drivers took exception with how the 22-year-old held his line out of a restart at Fontana Speedway in the same race.“If you told me I would finish fifth today, I would have given you a hug,” said Logano, who moved up to ninth in the standings.
