NASCAR: Bayne crashes in practice at Martinsville

When Trevor Bayne backs out to qualify on Friday at Martinsville, he will do so in a car that hasn't turned a single lap thanks to an incident in the closing moments of first practice.

Bayne and his team was forced to retrieve their back-up following a hard crash into the Turn 1 SAFER Barrier with 20 seconds remaining in the session. Bayne says his rear brakes were causing his Ford to wheel hop in the corners and he locked them up before backing into the outside retaining wall.

"I thought our car drove good in qualifying trim and it handled good, but I was really lagging in the braking zones," Bayne said after the crash. "We were giving up two to three-tenths in both corners and I tried to just push the braking zone a little bit more and it just started to wheel hop really bad.

"There was nothing I could do about it. Once it started bouncing, I tried to save it and once it got backwards, I stood in the gas and it just backed into the wall."

That practice session was the only one scheduled before knockout qualifying, so Bayne is simply hoping for the best when it comes to turning laps in his backup.

"You just go out there and act like you're in your primary," Bayne said. "I've got a great race team and one thing I've been proud of all year is they've been able to take our car from the shop and hit it unloading off the truck.

"The cars are turning good. They've been the right heights and not hitting the race track, so I trust my guys. The back-up car will be good. I just hate that we worked on that one in race trim and I tore it up."
