AVONDALE, Ariz. – Jimmie Johnson survived a close call and a succession of less-than-stellar restarts.
Matt Kenseth couldn't overcome handling problems that kept his car mired in traffic.
And Kevin Harvick, meanwhile, took advantage of Carl Edwards' fuel shortage to win his fourth race of the season in Sunday's AdvoCare 500 at Phoenix International Raceway, keeping alive his faint hopes of winning the NASCAR Sprint Cup Series championship in his final season with Richard Childress Racing.
The net result? Johnson, who finished third, widened his lead over the struggling Kenseth, who ran 23rd, and took a giant step toward his sixth series championship.
