really tough one, though."​

The top five cars had taken two tires after Segment 3, which put former leader Kasey Kahne (four tires) in fifth place to start the segment. McMurray was the first of those cars, which gave him the lead.

On the first lap of the segment, Jeff Gordon had some sort of mechanical failure and collected Martin Truex Jr. and Greg Biffle as he shot up the track. All three ended up hitting the wall together.

"Something broke," Gordon said. "It was going down the back straightaway, and as I got to the corner, I felt the front end set down and just go straight."

After the crash, some drivers said there was still oil on the track. Two-time segment winner Kahne was among them, and said he hitthe wall hard when he ran through some of the slippery stuff.

As the segment ended, Kahne then blew a tire and smashed the wall again.

Four cars gambled by not pitting after the second segment: McMurray, Kenseth, Brad Keselowski and Truex Jr. That quartet started Segment 3 as the leaders.

But soon, fresher tires prevailed. Segment 2 winner Kahne – who had made a pit stop – got back to the lead in just seven laps. Kahne then quickly pulled away and cruised to his second segment win of the night.

Harvick was second, followed by three of the cars who stayed out -- McMurray, Keselowski and Kenseth.​
