Sadler's recovery to fifth puts him back into the lead of the Nationwide standings by 4pts over Ricky Stenhouse, while Dillon's victory puts him within 19pts of Sadler's tally. With six races remaining in the 2012 season, Sam Hornish is starting to lose touch in fourth place, 46pts off the lead.
"I messed up at Richmond and Ricky had some bad luck today, and I think it's going to go back and forth from now all the way to Homestead." said Sadler. "It's going to be a good battle all the way to the end. I don't see anyone stretching out a comfortable lead before we get to November.
"But we are four points ahead, so we're right in the middle of this thing," he added.
