Denny Hamlin also got the jump on Edwards to take up the chase to the finish, leaving Edwards in third ahead of fellow Cup regulars Clint Bowyer and Brad Keselowski.
"Denny drove by and they just drove away from us," admitted Edwards, adding that it "made me feel a little bit better that they drove away and I didn't just give it up 100 percent on that pass."
After Bayne, the next-highest Nationwide Series regular was another Roush Fenway junior driver, Ricky Stenhouse Jr., who managed to keep his nose in front of Sam Hornish Jr. for sixth place while Joey Logano held off Elliott Sadler for eighth position.
In the Nationwide Series championship, that means Stenhouse has extended his lead over Sadler to 17pts with just two races remaining in the season. Justin Allgaier rises to third place after finishing in 14th in Texas, five spots ahead of Aric Almirola.
"That's good," declared a satisfied Stenhouse of his day's work. "That's better than where we were when we came in and that's really all we can ask for."
Danica Patrick, who will be competing in the Nationwide Series full time in 2012, came in a solid 11th place in her #7 car whose livery had special markings commemorating Dan Wheldon, who lost his life in the final IndyCar race of the season in Las Vegas in October. Patrick was also donating her specially designed helmet for the race to the memorial fund auction.
"She's definitely come a long way in my book," said Edwards of Patrick's growing confidence. "It took me a long time to get by her and finally, when I did get up right to the outside of her coming off the corner, I thought she did a great job of giving me just the right amount of room ... When I bumped her out of the way at Montreal, she went in the next corner and bumped me right back out of the way, so she's a good racer!"
