If you want to find a driver who is not particularly thrilled with Kurt Busch's victory in Sunday's STP 500 NASCAR Sprint Cup Series race at Martinsville Speedway, look to the No. 2 Team Penske garage stall.

Brad Keselowski thought he had a potential race-winning car, but his chances disappeared early in a pit-road collision with Busch.

Keselowski took his Ford to the garage and lost 31 laps while his crew made repairs. He finished 38th. After the race, Keselowski questioned Busch's judgment in driving aggressively on Lap 42 of 500.

"If you're going to be aggressive, wreck yourself, don't wreck me," Keselowski said. "I'll remember that when it's Lap 50 and he needs a break, and he'll find his --- turned around in the wall. Just like he tore my car up.

"Once or twice when it happens, you start to go, 'Hey, it happens,' but when it happens repeatedly, you just realize who the person is who's at fault, and you just got to make sure you show them you're not going to take that, and I'm not going to take it, and I know the 2 team's not going to take it." Busch was surprised at the vehemence of Keselowski's reaction to the incident, especially after Keselowski tried to exact payback on the track.

"Yeah, I can't believe he overreacted and he's as upset as he is," Busch said. "The 5 car (Kasey Kahne) was trying to pull into his box. Brad ran into the back of him. I steered right to go around Brad and then he clobbers our left-side door, and it's like, OK, accidents happen on pit road. It's congested.

"It's not a place to race, because of all the pit crew guys down there and I didn't think much of it, and then once we were back out running, he targeted us. He was aiming for us. He tried to flatten all four of my tires. That's a no-fly zone. That's a punk--- move and he will get what he gets back when I decide to give it back."
