HOMESTEAD, Fla.

Here’s a tweet for Brad Keselowski: NASCAR champion.

Roger Penske must like the sound of that, too.

The kid who stole the show at the season-opening Daytona 500 ended the year under the biggest spotlight of them all Sunday, beating five-time champion Jimmie Johnson to deliver the first Sprint Cup championship to Penske Racing.

With the Penske organization behind him, he delivered a trophy that had eluded “The Captain” since his 1972 NASCAR debut. Although his motorsports organization is considered the gold standard of openwheel racing — 15 Indianapolis 500 wins — and his empire has made Penske one of the most successful businessmen in America, his NASCAR team has always been just average.

Then came Keselowski, the blue collar, Twitter-loving, Michigan native who visited Penske in 2008 convinced the NASCAR team could win, too.

Three years later, they hoisted the Sprint Cup trophy together at Homestead Miami Speedway following Keselowski’s 15th-place finish Sunday night.

Keselowski needed 125 starts to win his first championship, the fewest starts since four-time champion Jeff Gordon won his first title in 93 starts in 1995. Keselowski also won a secondtier Nationwide title in 2010, his first season with Penske and the owner’s first official NASCAR championship.

Gordon, who avoided suspension this week but was fined $100,000 by NASCAR for intentionally wrecking Clint Bowyer last week at Phoenix, overcame the controversy to win the race in a 20th anniversary celebration for sponsor Dupont and Hendrick Motorsports.

It was Gordon’s first victory at Homestead, which leaves Kentucky as the only active NASCAR track where he’s yet to win.

Who did Gordon beat? Bowyer, of course.

And, Bowyer’s second-place finish moved him to a career-best second in the final standings. Third-place went to Ryan Newman, who got his break in NASCAR with Penske and spent seven seasons driving for the owner.

Keselowski started the race up 20 points on Johnson, who blew a tire and crashed last week at Phoenix to give Keselowski a nice cushion and needing only to finish 15th or higher in the finale to wrap up his first championship. But, the Penske team took nothing for granted — not after Will Power crashed in the IndyCar finale to blow a 17-point lead and lose the championship.

This one got tight, too, especially when Keselowski ran out of gas on pit road during green flag pit stops. It put him a lap down with Johnson leading, and Keselowski and crew chief Paul Wolfe frantically tried to figure out how dire the situation had become.

But minutes later, Johnson went to pit road for his own stop and pulled away with a missing lug nut. NASCAR flagged the Hendrick Motorsports team and Johnson was forced back to pit road for another stop.
