Carl Edwards had been grinding for 30 laps, doing everything he could to catch Joe Gibbs Racing teammate Kyle Busch in a two-way breakaway from the pack at Richmond International Raceway.

When he finally caught him on the last lap Sunday, and in the final turn, he had no time to think about what would be the prudent thing to do. Instead, Edwards focused on the reason they are racing: to win.

Edwards bumped his sometimes-volatile teammate off his racing line in the last turn and passed him to win his second consecutive NASCAR Sprint Cup Series race, and the fourth in a row for the Gibbs racing stable.

NASCAR said it was the first last-lap pass for a victory in the history of the premier series at the track, a span of 120 races.

“I wish it was anybody but my teammate that we had to race like that with, but big picture to me is we’ve both got some wins, we’re in the Chase, and it’s fun to have to race your teammate for the win,” Edwards said. “If the roles were reversed, I would have expected him to bump me the same way.”

Then in a bid to throw a bone to Busch, whose car was sponsored by Banfield Pet Hospital, he said: “If my cat ever gets sick, I don’t care how much it costs, I will take it to the Banfield Pet Hospital, if that helps.”

Edwards, who had fallen nearly 1.5 seconds behind after a restart with 36 laps to go, gradually ran him down, catching him on the final lap. Then he slipped underneath Busch, a master blocker in late-race situations, and nudged him just enough to allow Edwards to get inside him for his second consecutive victory. It was also the fourth in a row for the Gibbs stable, and fifth in nine races.

Busch seemed less than amused after being denied his third victory in the last four races.

“We just kind of gave it up a little bit there on the last lap, but I guess that’s racing and we move on,” he said. “… We had a really great car. … We were fast, maybe not as good as Carl was on the long runs, but we did everything right, everything we were supposed to do.”

Jimmie Johnson finished third, follow by Hendrick Motorsports teammate Kasey Kahne and pole-sitter Kevin Harvick. Gibbs placed all four of its drivers in the top seven, with Denny Hamlin sixth and Matt Kenseth seventh.

Edwards dominated the first half of the race, leading 120 of the first 200 laps, and he continued to lead until Kevin Harvick slipped underneath him with 170 laps to go.

Seven other drivers also led, with Busch, Harvick, Kurt Busch and Johnson also leading for at least 44 laps.

Tony Stewart raced for the first time this season, finishing 19th.
