Under overcast skies and with ambient temperatures around 40 degrees – a far cry from the mid-70s/sunny conditions expected for Sunday’s race – Keselowski posted a hot lap of 135.622 mph to pace the field.
“It’s really hard to get the tires up to temperature and get going,” Keselowski told Fox Sports. “Goodyear brings a great tire here that made the run in the heat, with all the brake heat and all those things, so when the track’s really cold like this, the first few laps are really dangerous.
“Everyone’s kind of fighting that, but temperatures will be up a little bit for tomorrow’s race and even for the next practice session, so that shouldn’t be an issue.”
Ryan Newman, seeking to pull himself into the Top 12 of the Chase Grid ahead of next week’s Challenger Round finale at Dover, was second-fastest at 134.920 mph.
“I think we learned a couple things, but in the end, it showed that we stacked up better than we did in qualifying, so we did at least some of our homework overnight,” said Newman.
Former New Hampshire winner Brian Vickers was third at 134.916 mph. Kevin Harvick (134.901) and Carl Edwards (134.853) completed the Top 5, with Kurt Busch, Clint Bowyer, Jeff Gordon, Jamie McMurray, and Kyle Busch following in Positions 6-10.
The Cup guys will have one more practice session later today at 11:30 a.m. ET.
Adam Cianciarulo (450) and Dylan Ferrandis (250) swept both motos of their divisions Saturday in the Lucas Oil Pro Motocross Championship event at Spring Creek MX Park in Millville, Minnesota, significantly impacting the points standings.
“Man, what a dream come true,” Cianciarulo said. “I really wanted to go 1-1 last round at RedBud and had that silly mistake. Today, we got the job done and made it happen. Two consecutive victories in the 450 Class just feels really good. I just want to keep the ball rolling.”
With three rounds remaining, Cianciarulo is ranked second in the standings at a 15-point deficit to Zach Osborne, who won three of the first five rounds.
In the 250 standings, Dylan Ferrandis jumped ahead of Jeremy Martin (who won three consecutive events earlier in the season) by three points (257-254).
Ferrandis beat third-ranked RJ Hampshire in the first moto and nipping Martin by 0.4 seconds in the second.
“That was a difficult race in the second moto and the pressure was on,” Ferrandis said. “It was really good for me to have that battle and come out on top in the second moto. The championship is really close and I think that we were able to put on a good show for everyone today. Jeremy [Martin] and I have a good relationship I think and we congratulated each other and talked about the battle after the race.”
