RICHMOND, Va. — There was a stretch of Saturday night’s race when all four of Joe Gibbs’ cars were leading the pack around Richmond International Raceway.

The team owner could barely stand to watch.

“That is the most nervous that I get,” Gibbs said. “I saw them up there. I saw some beating and banging there. I think that’s when I’m always the most nervous, when you’ve got your cars up front and having a good night.”

He should be used to it by now.

JGR continued its dominating season with an exhibition from its roster that ended with Matt Kenseth’s fourth win of the season. The win put Kenseth in a tie with JGR teammate Kyle Busch and six-time champion Jimmie Johnson for the top seeds in the Chase for the Sprint Cup championship.

The 10-race playoff series begins next Sunday at Chicagoland.

Kenseth has won three of the last six races, and JGR has won eight of the last 11.

“Certainly right now as a company we’re on a roll,” said Kenseth, who led 352 of the 400 laps.

The 16-driver Chase field was set in the regular-season finale, where only four spots were really up for grabs. Jamie McMurray clinched his berth as soon as he took the green flag, but Jeff Gordon, Ryan Newman, Paul Menard and Clint Bowyer all had to protect their positions.

Gordon had to finish 17th or better to guarantee his slot, and he finished a solid seventh.

Bowyer was in a little bit more of a precarious position as he came to Richmond ranked 16th in the field and unable to afford any mistakes Saturday night.
