Brad was able to get it. As a result, the yellow flag waved only twice for scheduled cautions that divided the race distance into its three stages. "What a great day for Team Penske and Ford".
Joey Logano won Sunday's Penzoil 400 at Las Vegas Motor Speedway.
Logano moved barely in front of pole-sitter and Stage One leader Kevin Harvick heading into the finish after an entertaining second stage.
In these seven Xfinity Series races, Busch earned one victory, as he won the June race at Pocono Raceway.
"I'd like to have one more lap", Keselowski said. "I think we might be top Chevy again". The Las Vegas-born racer was handed a drivethrough penalty for speeding on entry to the pitlane.
"The second half of the race, it's happened to us two weeks in a row", Harvick said. "The way the draft is, you can't just drive away".
"Even in the race right there I was either way too tight or way too loose I could never find a happy medium of it, but overall I feel like the Cup car's pretty good, so the M&M's chocolate bar Camry's got some speed to it as well and we ran a lot out there in traffic and in the pack and stuff so it's going to be an interesting race for tomorrow". "To be so close and get it at the end there, it was fun".
Kyle Busch finished third in his hometown race after overcoming a pit-road speeding penalty about halfway through the race.
Nine laps earlier, Busch had wrested the lead from eventual race victor Joey Logano, before heading pit road on Lap 129.
"That was more intense than I wanted it to be", Logano said. "Coming to pit road there, we tried a different brake package for us this weekend, and trying to make up time, and in order to get a bigger jump on the guys behind me coming to pit road there, just ruined it for us".
Kyle's brother Kurt Busch finished fifth. It was the first win for the 28-year-old driver at the Las Vegas Motor Speedway.
Keselowski had surged from sixth at the start of stage three to lead the race with 27 laps remaining. Facing little opposition, he stormed off to the stage victory.
Extending his stint at the end of the second stage, Busch was able to stay out when the rest of the field pitted at the start of stage three.
