Kyle Busch Capitalizes On Wreck At Cali

Sprint Cup: Fantastic finish worthy of Hollywood

By Terry Blount | ESPN.com

All you naysayers, I have a few questions for you.

Still have doubts about the Gen-6 race car? Still think Fontana is boring racing? Still wondering when NASCAR will return to the good old days of fightin' and wreckin'?

Still looking for some bad-blood rivalries? Still think Dale Earnhardt Jr. can't lead the standings and compete for the title?

If you answered yes to any of those questions, you clearly aren't paying attention. Or maybe you just missed the race Sunday, which was one of the most entertaining and drama-filled finishes in years.

Kyle Busch zoomed by Joey Logano and Denny Hamlin when the former teammates-turned-enemies wrecked on the final lap, battling for the win side by side.

That was the late-race fight. The postrace fight came moments later when a furious Tony Stewart went after Logano with intent to harm, using his fists.

All but forgotten was Busch's first Cup victory in almost a year and Earnhardt moving to the top of the point standings. Earnhardt overcame a bad pit stop and raced from midpack to second in the final laps, an impressive drive to the front.

"This is Hollywood, the land of drama," ACS president Gillian Zucker said after the race. "We certainly got that today."

Calling Fontana Hollywood is a bit of a stretch, but we get the point. Zucker was overjoyed after her much-maligned speedway put on a great show in the new car.

"The Gen-6 car was designed for this type of racetrack," she said.

Five races into the season, the Gen-6 is passing the test. So did ACS on Sunday with its biggest crowd in years.

"It was an amazing race," said Kurt Busch, whose fifth-place finish was his second consecutive top-5. "It was great watching everybody race and put on a good show, and I think the cars performed well here."

"Everyone at [Auto Club Speedway] should applaud themselves for the show they had here today," said Steve Letarte, Earnhardt's crew chief.

The ending was unforgettable, but probably wouldn't have been as exciting were it not for two guys who really don't like each other. Hamlin wrecked Logano last week at Bristol, and Logano had words with Hamlin afterward, upping the ante on their Twitter feud.

So having those two drivers fighting for the win at the end meant neither man was going to give an inch on the track.

"We weren't going to win if it wasn't for those two battling," Kyle Busch said. "If they would have been single file and just racing, it would have gone down in order."

It didn't, and the only downer of the day was Hamlin's vicious head-on crash into a concrete wall on the inside part of the track. It sent Hamlin to the hospital, where he stayed overnight to undergo tests on a possible back injury.

Why any track still has concrete walls without the SAFER barrier in front of it is inexplicable.

That's an argument for another day, but two weeks from now in Martinsville, expect more arguments on the track, and maybe off it, between Logano and Stewart.

While everyone thought the only feud was between Logano and Hamlin, Stewart became the latest Logano hater, believing Logano almost blocked him into the grass on the final restart.

Fists and feuds, tradin' paint and last-lap fury, Sunday was old-school NASCAR at its best.

Who would have thought it could happen at Fontana? Maybe Zucker comparing ACS to Hollywood isn't such a stretch after all.
