Keselowski gets The Captain his Cup title
HOMESTEAD, Fla. (AP) — 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.
It's a trophy that had eluded Penske since he first entered NASCAR in 1972. Although his motorsports organization is considered the gold standard of IndyCar racing — 15 Indianapolis 500 wins — and his empire has made Penske one of the most successful businessmen in America, his NASCAR team operation was always just average.
Then came Keselowski, the blue collar, Twitter-loving, Michigan native who convinced "The Captain" his NASCAR team could be a winner, too.
Panthers lose heartbreaker to Bucs in OT
CHARLOTTE (AP) — Josh Freeman threw a 15-yard touchdown pass to Dallas Clark in overtime to cap a comeback.
It was Freeman's third touchdown pass of the game for the Buccaneers (6-4).
Carolina appeared to have the game in hand after a 29-yard touchdown pass from Cam Newton to Brandon LaFell put the Panthers (2-8) up 21-10 with 4:34 left in the game. But after a 40-yard field goal by Connor Barth, the Panthers were forced to punt, and Freeman led the Bucs 80 yards on seven plays in 50 seconds with no timeouts.
He finished the drive with a 24-yard touchdown pass to Vincent Jackson between three defenders with 12 seconds left. Freeman went back to Jackson for a 2-point conversion on a slant route to send the game into overtime.
