Martin finished 0.586 seconds ahead of Greg Biffle for his first Nationwide victory in three years.
Martin hit the rear bumper of Edwards on lap 195 and it sent him spinning into Keselowski. The two leaders spun leaving Martin in the lead.
"I'd like to be really mad at Mark, but Mark's a heck of a guy, he's a guy we all look up to, I'm sure he just made a mistake," said Edwards.
On the restart, Martin got a three length lead on Biffle.
