Now Keselowski is elbowing his way into the season-ending Chase for the Championship picture and making more than a couple of other drivers nervous.
Keselowski, who also won at Bristol and Talladega, now is now 10th in the standings. The top 12 drivers after 26 races make the Chase.
With nine races to go, Matt Kenseth is first in the standings, followed by Dale Earnhardt Jr., Jimmie Johnson, Greg Biffle, Denny Hamlin, Kevin Harvick, Clint Bowyer, Martin Truex Jr., Tony Stewart and Keselowski.
In three of Keselowski's first seven starts, he finished near the bottom. He also had not cracked the top 10 in his four previous starts before coming to Kentucky.
But he has had his Penske Dodge in contention in almost all the rest of the 17 races so far.
"The only thing that means anything is who's in the top 10 and who has the most wins when the Chase gets going," Keselowski said. "That is the only thing that matters."
