For the sixth consecutive Nationwide race, Busch led the most laps, but hung on to capture his fourth victory of the season and the 25th of his career. At age 24, he became the youngest driver to win that many races in the series.

"It's great to be able to come back here and finally get this monkey off our back, whatever it's been," Busch said. "This has just been a hard couple of weeks."

Last week, Busch blew a tire and then his Joe Gibbs Racing teammate Joey Logano shoved him up the track after a late-race restart. Brad Keselowski grabbed the lead and drove on to victory.

Busch led in the late-going at Charlotte, but pitted under green during the last round of stops. Mike Bliss had yet to pit and moved to the front before rain fell on the track. NASCAR called the race shortly after, with Bliss picking up the victory.

At Darlington, Busch suffered a flat right-rear tire after he ran over debris from a wreck involving Joe Nemechek and Scott Lagasse Jr., which set up a green-white-checkered finish. Busch had to pit during the caution, handing the lead over to Matt Kenseth, who went on to win the race.

Busch was determined to win at Nashville with 173 of 225 laps led. But Keselowski made a late-race charge, which came up short at the end.

"Keselowski was better than us at the end of the race, but I was trying to be conservative and not let anything happen...again," he said.

Busch won at Nashville for the first time, while Keselowski, the defending race champion and last week's winner at Dover, finished second.

"We did what we need to do, ran up front and put ourselves in position like we did at Dover, but we just didn't catch a break like we did at Dover," Keselowski said.

Edwards, a three-time Nashville winner, was third, while Bliss and Jason Leffler rounded out the top-five.

"We made some progress," Edwards said. "(Busch) has bad luck, and we've been able to capitalize on it, but we had to run better, and tonight was the most competitive we've run for a long time."

Stephen Leicht, Steve Wallace, Michael McDowell, Erik Darnell and Brad Coleman finished sixth through 10th, respectively.

With the victory, Busch padded his points lead to 65 points over Edwards.

The 300-mile race at Nashville featured just four cautions, but two were for multi-car pileups.

Ricky Stenhouse Jr. triggered a five-car pileup on lap 124 when he lost control and slid into the wall. Sean Caisse, Trevor Bayne, Jason Keller and Cale Gale all wrecked while trying to avoid Stenhouse. NASCAR had to stop the race briefly for track cleanup efforts.

"There was a lot of good race cars involved and did not want it to end this way," Stenhouse said. "I'm not sure what happened. I might of just lost it, but can't say for sure."

John Wes Townley caused a multi-car wreck on the third lap when he spun and smacked the wall. Mike Harmon also hit the wall, with Casey Atwood and Brad Baker ramming into him.

During a round of late-race pit stops, Brendan Gaughan slammed into the back of Marc Davis on pit road. Davis was in the process of driving his car into the garage after experiencing electrical issues.

"I don't know if (Davis) is dumb, his crew chief is dumb or his spotter is dumb, but in the middle of the race when you end up turning left while people are coming onto pit road for green-flag pit stops is asinine," an angry Gaughan said after the race. "Maybe he needs to look that word up."
