Tony Stewart celebrates after winning the NASCAR Sprint Cup All-Star race at Lowe's Motor Speedway on Saturday night.

Kenseth was second, followed by Kurt Busch, Denny Hamlin and Carl Edwards.

The format was once again changed, this time to cut the 100-lap race into four segments that culminated with a 10-lap sprint to the finish. It was a nod to races past, which had a history of dramatic dash-for-the-cash finishes.

After a follow-the-leader parade for most of the first three segments, the action picked up at the drop of the flag of the final shootout. Kyle Busch used a three-wide pass to dart from fourth to first, aggressive driving that slowed the cars behind him. Denny Hamlin ran into the back of Jimmie Johnson, sending Johnson into a spin that he masterfully saved from a race-ending accident.

A caution period set up another restart, and this time Jeff Gordon raced to the front. Newman decided to enter the action with a three-wide move to the outside, and Gordon and Kyle Busch touched at least once before all three cars collided.

It sent Gordon into a spin through the grass then back up across the track, where he crashed into the outside wall to end his race.

“It’s the All-Star event. That’s just a bunch of guys racing really, really hard,” Gordon said. “I heard three-wide right at the last second.”

Kenseth eventually moved to the front, but he and Busch knew Stewart was coming quickly. Stewart was third on the final restart with five laps to go, and made several charges for the lead before finally getting past Kenseth with two laps remaining.

The late-race action moved the attention back to the track after a week spent discussing Jeremy Mayfield’s indefinite suspension for failing a random drug test.

Despite his ban from the track, Mayfield was on track property early Saturday night, complete with camera crew in tow, as he watched J.J. Yeley drive the Mayfield Motorsports entry to a 22nd-place finish in the preliminary race.

Mayfield spoke with reporters who found him in the infield, insisting his positive test was not because of illegal drug use. Instead, he said it was the combination of a prescription drug, which he would not identify, and Claritin-D, which he said he used to combat allergies at Richmond that were “really, really bad.”
