Keselowski says he'll have a beer, tweet, stay focused

• Keselowski says he's staying focused, will enjoy big dinner, beer and an easy sleep

HOMESTEAD, Fla. -- Jimmie Johnson says he'll sleep well before Sunday's NASCAR season finale at Homestead-Miami Speedway.

Will pleasant dreams also await Brad Keselowski, who carries a 20-point lead over Johnson into the Ford EcoBoost 400?

"I don't know," he said, cracking one of his few smiles during an 8-minute session with news media Saturday. "I've never been before a big championship event like this. I'm going to say I will. I'm going to eat a big meal, have a beer and fall easily asleep, I imagine. I sleep pretty well."

There were two practice sessions and one final round of mind games Saturday between the two contenders for the Chase for the Sprint Cup.

After qualifying third Friday, Keselowski received another break Saturday when pole-sitter Joey Logano wrecked in the final practice. Relegated to a backup car, Logano will start from the rear of the field, and Keselowski will move onto the inside of the front row for the green flag and improve his chances of leading a lap Sunday.

"I hope he tries really, really, really hard to lead that first lap," Johnson said with a smile. "I know (Marcos) Ambrose next to him is going to try hard, too. So that could be good for me."

Keselowski needs to finish 15th or better to clinch his first championship (and first for Penske Racing) in NASCAR's premier series.

"Very pleased with how our car finished up," Johnson said after posting the 17th-fastest lap in the final practice of the season. "It's really nothing for me to lose sleep about tonight. We finished on a high note in practice. Just go to bed, get up and get to work for tomorrow.

"Easy from my standpoint because I've got nothing to lose. We'll see what they do on the other side."

Asked if he was paying attention to the five-time champion's incessant reminders of the pressure facing him, Keselowski said he was.

"I haven't ignored it," he said. "I laugh at it because if we could trade places he would in a heartbeat."

Though exhibiting a more steely resolve than his loose demeanor during the previous two days ("I'm still in a focused race mode," he said), Keselowski maintained he controlled his destiny in the title race.

"I think our car's pretty good," he said after turning the fourth-fastest lap in practice. "We have enough speed to control some of our destiny. Just ready to get it on."

Keselowski said his No. 2 Dodge compared favorably to the 1.5-mile races earlier in the Chase at Chicagoland Speedway (where he passed Johnson for the victory) and Texas Motor Speedway (where he finished second to Johnson).

"It's a comparable speed and comparable feel but could always be better," he said. "I don't think we're drastically better than everyone else. That's my focus."

And it apparently would be for the rest of Saturday night.

"I don't plan on relaxing much aside from maybe tweeting," he said. "I plan to do a lot of focusing on what it takes to get the job done."

Johnson, who hasn't won at Homestead, believes his No. 48 Chevrolet is top-five caliber.

"We'll work on that tonight and put some final touches on it," Johnson said. "I knew coming into this weekend I'd have a big hill to climb with (Keselowski) and the points lead they have. They've done their part and have been very competitive all weekend long. We'll just have to see how that race goes. I feel we've made our car a lot better through the course of the weekend. The last two race runs we had were pretty strong and in the mix."

Other drivers weren't so sure. Denny Hamlin said after the first practice that Keselowski "is smiling for sure. I don't think (Johnson) has the speed to run with those guys anyway. They're going to have to rely on something catastrophic happening to (Keselowski)."

But seven-time champion Richard Petty said the title would be awarded to the "guy who is the most lucky," and Keselowski subscribed to the same theory.

"I think we have enough speed," Keselowski said. "It'll come down to whether it's meant to be or not meant to be."
