DAYTONA BEACH, Fla. (AP) — Kyle Busch climbed out his car window, pulled off his gloves and helmet in disgust and started walking back toward the finish line.

A safety crew coaxed him into a pickup truck and drove him to the infield care center — the same place he ended his last Sprint Cup race at Daytona International Speedway.

"I think he's got a little bit of a headache, but hopefully he's going to be OK," car owner Joe Gibbs said.

Busch might have a stomach ache, too, if he thinks about his two Cup races at Daytona this season.

With his No. 18 Toyota out front and the checkered flag in sight Saturday night, Busch looked like he might snatch a win from Tony Stewart in the Coke Zero 400.

Instead, Busch ended up in the wall, out of contention and with another trip to the care center. Stewart, meanwhile, won his second race in five weeks and extended his lead in the series standings. Jimmie Johnson was second, followed by Denny Hamlin, Carl Edwards and Kurt Busch.

Kyle Busch finished 14th, sliding across the finish line backward in a mangled car.

"It's a big disappointment," crew chief Steve Addington said. "We sat there, was patient all night long. We were just fine. ... We were in position to go for the win and we end up wrecked. What are you going to say?"

Busch said nothing.

He spent a few minutes inside the care center, blew off reporters and then bolted toward his motorhome on a golf cart.

"It's a tough place to race," Gibbs said.

Busch has learned that the hard way this season.

He led a race-high 88 laps in February's season-opening Daytona 500 and was certain he had a good enough car to make it to Victory Lane. Dale Earnhardt Jr. ended any chance he had of getting there.

Earnhardt triggered a massive wreck with 75 laps remaining, and Busch was right in the middle of the mess and ended up 41st.
