As Brad Keselowski flaunted his fast car by leading session after session at New Hampshire Motor Speedway, Joey Logano took a good-natured swipe at his teammate by asking him via Twitter to slow down. Team Penske is hot - the hottest organization in NASCAR with four wins in the last five races - and Logano and Keselowski are ruthless right now about results. Just because we're in the next (round) doesn't mean we're going to take a week off next week.'' This 16-driver Chase under a new elimination format was supposed to pit Penske against mighty Hendrick Motorsports, but it's been all Penske through the first two races. Well, Kasey Kahne could be eliminated Sunday at Dover, six-time and defending champion Jimmie Johnson has been mediocre at best, and Jeff Gordon and Dale Earnhardt Jr. aren't yet on the same level as the two Penske teams.
