Brad Keselowski fended off Kyle Busch to claim his fourth Nationwide Series win of the season at Memphis.

The JR Motorsports driver, who is set to make the switch full-time to the Sprint Cup with Penske next year, turned a few drivers around, made a great restart to claim the lead in the closing stages, and then held on to his car out of the last corner of the race as Busch tapped the rear of his car in a desperate attempt to avoid another second place finish.

Keselowski was involved in a couple of incidents, first with Penske rookie Justin Allgaier and then with Carl Edwards in the closing stages, spinning the Roush Fenway driver around at the exit of turn two.

On the following restart and back in fifth place, he made an impressive move to claim the lead of the race passing all those ahead nearly all at once. He pulled away until the caution came out again with only nine laps to go, after former race leader Michael Annett got spun against the barrier.

The green flag waved with only five laps to go and Keselowski made a great restart, leaving his rivals behind to fight for second place, although he had to make it all over again as the caution came out for the final time with only two laps to go, when Steven Wallace got spun after making contact with Matt Kenseth.

On the last restart for the green-white-checkered finish, Keselowski managed to stay ahead of Busch, but the points leader kept close enough to make a last-lap banzai move.

At the exit of Turn Four and with the checkered flag within sight, Busch turned him sideways, but Keselowski was able to avoid getting spun to narrowly beat the Joe Gibbs racer.

"That's short track racing," said Keselowski. "This tire is so slick, this racetrack so tight and it's really hard to see with all that sun. I got in the back of Carl and that's the one I feel the worst about. I didn't know he was going to make that move.

"I might have got a little too far a couple of times but the fans love it and we've got to thank them, and we've got to put a show on that they like, and they liked that show, you can see it right out here."

Busch finished second for the 11th time this year and said he wasn't trying to spin Keselowski out.

"I was just trying hard to win the race," Busch said. "I'm sorry we didn't get one spot better, but I couldn't put it to myself to spin him out."

Jason Leffler finished third ahead of Mike Bliss, who led a race-high 85 laps before losing ground in the closing stages. Brendan Gaughan also led the race but lost out in the final pit stop, dropping three places and out of contention for victory, although he still finished fifth.

Carl Edwards recovered after being hit by Keselowski to finish the race in sixth place, but he is already 215 points behind Busch with only three races remaining.

"I hope it's just a racing deal," said Edwards about the incident with Keselowski. "I like Brad, I like him a lot. He probably didn't go out there thinking 'I'm going to wreck him'. He probably didn't give me the space either."

Besides his victory, Keselowski won a $75,000 bonus from Nationwide for scoring the most points in the four stand-alone events of the season.
