Jimmie Johnson won’t plan any parties this week, or waste a minute pondering his place in NASCAR history.

Instead, he’ll spend this next week mentally running laps around Homestead-Miami Speedway. Johnson’s win at Phoenix International Raceway on Sunday moved him one step closer to a record fourth consecutive championship, which can be wrapped up with a mediocre run in the finale.

“I’m not one to let my mind wander and think about the possibilities — I’ve always known I’ve got to go out and race the race, get it done,” he said. “When I go home, I’m going to be (mentally) driving laps, what I think I need to do in qualifying trim so I can put my best effort in on Friday. Same thing for race practice on Saturday, and go racing Sunday.”

Johnson cruised to a dominating win at Phoenix, leading 238 of the 312 laps en route to his fourth victory in the Chase for the Sprint Cup championship. It widened his lead in the standings to 108 points over Hendrick Motorsports teammate Mark Martin, and Johnson needs only to finish 25th or better at Homestead to wrap up the title.

The strong showing came a week after a fluke accident at Texas chopped a chunk of points off Johnson’s lead, and the rebound was considered something of a “statement.”

“I guess in the end it could be looked at like that,” Johnson acknowledged. “It was, ‘Hey, guys, you know, we need to step up and get it done … we need to show what we’re made of, we need to get this done.’ I’m very proud of the fact we looked each other in the eyes, knew what we had to do, and delivered.”

Johnson was wrecked on the third lap at Texas, and sat inside his disabled race car as his crew did a total rebuild of the Chevrolet. He limped to a 38th-place finish that sliced his lead in the standings to just 73 points over Martin.

Martin, who won at Phoenix in April, delivered a fourth-place finish Sunday — not enough to keep pace with Johnson.

“We gave it everything we had,” Martin said.

It’s technically not over: Martin has gained 108 points on Johnson nine times in 265 races, including last weekend at Texas. He did it once at Homestead, in 2005. But Martin is not counting on catching Johnson this year, and the sentimental favorite for the championship will likely finish second in the final standings for a fifth time.

He’s the only driver still in mathematical contention to catch Johnson. Fellow Hendrick driver Jeff Gordon will be eliminated as soon as Johnson starts next week, and Johnson’s win at Phoenix knocked everyone else out of the running.

Despite the harsh reality of his position, Martin is refusing to concede to Johnson and said he won’t let up next week in Homestead as he tries to at least stave off Gordon for second in the final standings. But should Johnson coast to the win, Martin will be fine.

“We’ve still got to go to Homestead and run like this again, because we still have heat behind us, Jeff Gordon, especially,” Martin said. “I definitely have been beat by the best — Jeff Gordon, Tony Stewart and Dale Earnhardt. It wouldn’t embarrass me if it was Jimmie Johnson as well.

Jeff Burton finished second and was followed by Denny Hamlin, Martin and pole-sitter Martin Truex Jr.

Kurt Busch, winner last week at Texas, finished sixth. Clint Bowyer was seventh, followed by Juan Pablo Montoya, Gordon, and David Reutimann.

Nobody was surprised to see Johnson in Victory Lane, particularly since he’d had such a rare race the week before.

“Anytime that Jimmie is down is not usually because of performance, it’s usually because of an incident like last week,” Hamlin said. “There was no doubt in my mind they were going to come this week and make a statement.

“Obviously leading all the laps pretty much and winning the race sends a statement out there that he is the best, that they’re not going to be denied this year.”

Johnson, though, was reluctant to start any celebration after his win. Although his Hendrick team initially reacted as if the title had been locked up, the No. 48 crew quickly settled down in Victory Lane.

He admitted the win at Phoenix gave him a small sense of relief after “the carpet was jerked out from underneath our feet” at Texas, but it also provided a valuable lesson of not looking too far ahead. Johnson promised to remain focused this entire week and not get too far ahead of himself in thinking about his impending trip into the record books.

“Texas was such a good lesson,” he said. “And I hope that the points we lost in Texas isn’t what keeps us from winning this championship.”
