LAS VEGAS – Another race, another victory for Jimmie Johnson, and yet another round of griping about the NASCAR champion’s dominance.

Only this time, there was a silver lining for those ready to see someone else hoist the Sprint Cup trophy: His competitors are clearly closing the gap.

Johnson reeled in teammate Jeff Gordon at Las Vegas Motor Speedway, where the four-time defending champion won for the second consecutive week. He needed luck to win last week at California and strategy Sunday at Las Vegas.

Sooner or later, though, he’s going to run out of ways to win.

“We don’t feel invincible,” Johnson said.

And he shouldn’t.

Kevin Harvick finished second for the second straight week, then showed signs of the swagger that only Harvick can pull off, and only when he’s running well.

“We can run with them, and they know it,” said Harvick, the points leader.

Gordon, who dominated the race only to have to settle for third when his pit strategy backfired, was buoyed by his ability to lead 219 of the 267 laps.

“I think we’ve got more of what we showed today,” he said. “We’re going to show a lot more. I think we’re just starting to tap into it.”

Johnson took four tires on the final pit stop in a race-winning decision that gave him his 49th career victory and fourth at Las Vegas. It also made Johnson the career victory leader on 1.5-mile speedways with 15 — one more than Gordon, Dale Earnhardt and Richard Petty.

Informed of his intermediate track dominance, he did a celebratory fist-pound with crew chief Chad Knaus and shook team owner Rick Hendrick’s hand.

This one required beating Gordon, a Hendrick Motorsports teammate who hasn’t won in almost a year.

Gordon was out front when Kevin Conway’s spin brought out the final caution, and he debated strategy with crew chief Steve Letarte.

The call was made at the last second for Gordon to come in, and Letarte changed just two tires to get Gordon back on the track before the competition. Knaus called for four tires in a decision that put Johnson in fourth on the restart.

Clint Bowyer, who didn’t pit, restarted as the leader with 34 laps to go, but the Hendrick cars immediately split him to move back to the front. Gordon held the top spot for 17 laps but fretted several times as Johnson looked both inside and out.

Johnson finally scooted past with 17 laps to go. He quickly pulled away, and Gordon was unable to hold off Harvick for second place.

“If we won the race, we’d look like geniuses, Steve would have. The fact that we lost the race, now Chad looks like a genius,” Gordon said.

“I talked to Steve briefly after the race. He’s pretty upset, obviously. I think he just felt like more people were going to take two tires. Shoot, we were thinking for a split second to stay out.

“I felt like we needed to come in and get some tires, but I felt like two tires was the right call, too. We just needed (Johnson) to take two. They did the opposite of us. That won the race for them.”

Knaus quickly defended Letarte. The two work closely at Hendrick Motorsports and waged a classic battle for the 2007 championship.

“I didn’t outsmart him. He did not make the wrong call,” Knaus said. “There wasn’t a wrong call to make. They came in first. They wanted to maintain track position because track position is so critical. Only way for us to beat them was to do something different.”
